Resumen de investigación

▶ La oportunidad y el coste de escalar agentes

El narrador plantea que los agentes mejoran, pero pueden elevar la factura. Cuenta que preguntó en Dreamforce cómo ampliar la adopción de IA y participó después en un panel sobre el coste de desplegar agentes a escala. Quiere que las empresas puedan usar agentes para tareas más ambiciosas sin afrontar una incertidumbre financiera excesiva. Propone reconsiderar cómo se hace el trabajo y partir del resultado de negocio deseado para mantener el valor y hacer asequible esa capacidad para empresas de distintos tamaños.

▶ Adopción al integrar agentes en el trabajo cotidiano

El narrador sostiene que las decisiones sobre cambios, modelos y gasto deben partir del valor de negocio. Resume que en la conferencia se habló de seguridad, crecimiento, modelos y adopción, y describe su pregunta a Mark sobre cómo conseguir que distintos grupos usen Agentforce: desde quienes adoptan pronto hasta quienes apenas usan IA o se resisten a ella. Destaca la respuesta sobre integrar agentes en interfaces y herramientas que la gente ya usa, como Slack, para ayudarles dentro del trabajo existente y reducir la barrera de probarlos. Según su planteamiento, una experiencia útil puede animar a repetir el uso y a pedir más, facilitar el interés de colegas y responsables, y extender la adopción más allá del grupo inicial. Aclara que tener Slack no significa que una empresa ya haya resuelto la adopción; el reto es que los agentes pasen de ser una novedad a ser fiables y dignos de confianza.

▶ Más capacidad puede multiplicar el consumo

El narrador pregunta cómo hacer fiables los agentes, conectarlos con información real de la empresa y pagar su uso si un experimento exitoso se vuelve cotidiano. En un panel con la participación de personas de Salesforce, PwC y Pepsi, atribuye el cambio a modelos que, según él, desde enero pueden usar herramientas, trabajar con información y completar tareas más largas sin dividirlas en pequeñas preguntas y copiar resultados entre sistemas. El mayor alcance de una solicitud puede implicar varias llamadas al modelo, más lectura y más uso de herramientas. Como ilustración, plantea diez veces más ejecuciones y cien veces más tokens por ejecución, que juntos equivaldrían a mil veces el consumo; aclara que esos números son aproximados, aunque afirma que grandes aumentos pueden aparecer sin usos inusuales. Menciona modelos de frontera que cobran 50 dólares por millón de tokens de salida y señala que entrada y entrada en caché tienen otros precios. Opina que enviar cada decisión al modelo más caro dificulta controlar costes a largo plazo. Rechaza atribuir el aumento solo a usuarios que consumen demasiados tokens: también influyen las decisiones de diseño del sistema, del entorno del modelo y de la infraestructura.

▶ Rediseñar el proceso desde el valor de negocio

El narrador reconoce que elegir modelos más baratos puede aportar valor, pero propone primero preguntar por qué se hace el trabajo. Compara los procesos heredados con un sobre interdepartamental que viajaba de persona en persona y cuya portada registraba el recorrido. El sobre pasó a ser correo electrónico y luego un ticket, pero todavía puede exigir resumir, reformatear y explicar información para el siguiente equipo. Algunos pasos pueden tener motivos válidos; otros surgieron porque las personas o los sistemas no podían compartir información de otra manera. Añadir agentes en cada parada puede acelerar el recorrido sin eliminarlo. Recomienda empezar por unos cinco a ocho grandes flujos de valor desde la perspectiva de dirección —la cantidad y división dependen del negocio— y trazar la ruta necesaria para ganar un cliente, entregar lo vendido, conservarlo o cobrar. Partir de los procesos existentes puede hacer que cada equipo presente sus pasos heredados como requisitos; entonces se contratarían agentes para reproducir el trabajo tal como se recibió.

▶ El ejemplo de una cotización y los pasos prescindibles

El narrador presenta como ejemplo imaginado, aunque dice haberlo vivido y que otras personas también, una solicitud de cotización: alguien la resume para operaciones de ventas, otra persona revisa la cuenta, alguien traduce la solicitud a una configuración de producto, se usa el sistema de precios y la cotización pasa por las revisiones necesarias antes de responder al cliente. Identifica los resultados necesarios: una cotización correcta y autorizada, un registro de que se generó y una pregunta para lo que no pudo resolverse. En cambio, un resumen que solo existe porque un equipo no puede leer el sistema del otro podría dejar de ser necesario. Recomienda diseñar la ruta hacia la cotización con el mínimo de traspasos, pues eliminar pasos que ya no tienen razón también evita consumir tokens en ellos. Una ruta más corta puede reducir fallos, versiones divergentes y trabajo de reconstrucción, y permitir que el modelo considere el problema completo. Los responsables del resultado de negocio deben participar en el diseño porque quizá un ingeniero no tenga autoridad para eliminar un documento interdepartamental. Aun así, ciertos requisitos, como aprobar descuentos y registrar ofertas, permanecen. El tiempo que recupera el equipo podría destinarse a más ventas, mejor servicio o menor sobrecarga, según la decisión de la empresa; no implica automáticamente reducir la plantilla.

▶ Elegir modelos según el trabajo y dirigir los casos difíciles

El narrador cuenta que habló con Rohan Kumar, a quien identifica como presidente y responsable de plataforma e ingeniería de Salesforce, sobre despliegues de agentes con clientes. Tras el uso de asistentes para redactar correos, propone trabajar con clientes en tareas concretas, observar qué funciona y cómo escalarlo. También señala que acelerar la escritura de código no acelera por sí sola la revisión, integración y puesta en producción; conviene seguir el trabajo hasta encontrar dónde se atasca. Para escoger modelos, distingue entre cálculos regidos por reglas, interpretación del lenguaje del cliente y excepciones con datos en conflicto que requieren investigación. Sostiene que no todas las tareas necesitan la misma inteligencia y que un modelo puede equivocarse si no dispone de los datos adecuados. Para trabajo ya resuelto, propone usar software convencional, como un CRM o una herramienta de precios, y reservar el modelo para interpretar la solicitud, detectar datos ausentes y explicar resultados. Afirma que modelos de pesos abiertos o servicios alojados más económicos pueden bastar para muchos casos si están bien configurados, pero advierte que los pesos abiertos no son automáticamente más baratos de operar y que un modelo pequeño no siempre es el adecuado. Recomienda preguntar qué modelo puede hacer bien cada trabajo, en vez de cuál gana en general. Describe clasificadores que derivan solicitudes rutinarias a modelos de pesos abiertos y casos excepcionales o delicados a modelos más capaces. Reservar estos últimos para los problemas más difíciles es su propuesta; identificar de forma fiable el trabajo rutinario es un reto y requiere pruebas. Según él, cuando funciona, puede ampliar el acceso a capacidades útiles a un coste distinto, manteniendo disponible el modelo caro cuando la tarea lo requiera.

▶ Adaptar el entorno al modelo

El narrador advierte que al cambiar de modelo también puede ser necesario cambiar el entorno que lo acompaña. Define ese entorno de forma amplia: instrucciones, herramientas, información, verificaciones y el recorrido de la tarea. Según su explicación, un modelo menos capaz puede necesitar más estructura para trabajar de manera predecible. En el ejemplo de cotización, podría encargarse de identificar producto y cantidad y detectar qué información falta, mientras el software verifica campos del CRM, consulta precios y aplica aprobaciones. Para modelos de frontera usados en excepciones difíciles, el narrador prefiere un entorno más flexible que presente el problema del cliente, las pruebas, herramientas generales y el resultado esperado, sin imponer cada paso de razonamiento; afirma que demasiadas restricciones pueden entorpecer el uso de su capacidad. Así, propone más estructura para modelos de pesos abiertos que ejecutan procesos a escala y menos para el trabajo investigativo de modelos más capaces, ajustando el sistema a cada tarea. Menciona que preparó una guía de ahorro de tokens con 15 cambios, que incluye conservar resultados aceptados y seleccionar la información necesaria, y vuelve a preguntar cuánto trabajo se mantiene solo porque lo exigía el sistema anterior.

▶ Evaluar si el agente hizo bien su trabajo

El narrador sostiene que no basta con que un agente parezca satisfecho, una persona esté contenta o el resultado del modelo barato parezca aproximadamente correcto: hay que comprobar si el proceso funciona. Compara la evaluación de agentes con las evaluaciones laborales humanas y señala que un agente con responsabilidades requiere retroalimentación con más frecuencia que una vez al año. En el caso de la cotización, propone verificar el precio contra el sistema de precios, confirmar que hubo aprobación y que se actualizó el registro, y reconocer cuándo preguntar algo al cliente es la acción correcta aunque la cotización aún no esté terminada. También puede hacer falta juicio humano para evaluar si la explicación responde a la preocupación del cliente y si un documento formalmente válido contiene la respuesta correcta. Por eso considera que diseñar evaluaciones es una habilidad humana además de una capacidad del agente, y propone enseñarla. Las comprobaciones deberían ayudar al agente a detectar información faltante, reconocer que el trabajo terminó y corregir lo que falló; de lo contrario, advierte, puede haber una ejecución larga y costosa sin saber si aporta valor.

▶ Balancear coste, valor y rediseño del trabajo

Al recapitular Dreamforce, el narrador conecta la mayor adopción y capacidad de los modelos con la posibilidad de eliminar trabajo y rediseñar el camino hacia un resultado de negocio. El consumo puede crecer porque hay más usuarios y más tokens por agente, pero acortar procesos y asignar cada tarea al modelo apropiado también puede reducir lo que se paga. No ofrece un porcentaje universal de ahorro: dice que cada negocio debe comprobarlo. Sugiere mirar más allá del coste del modelo y valorar si el equipo atiende a más clientes, da respuestas correctas antes o dedica menos tiempo a reparar traspasos. Una factura mayor puede ser razonable si acompaña a más valor; cita como caso diferente seis agentes que redactan informes que nadie lee. Por eso recomienda no juzgar solo por el consumo de tokens. Quiere que la IA esté disponible en las herramientas cotidianas sin que cada consulta parezca un error financiero, y asigna a quienes diseñan los sistemas la responsabilidad de hacer ese uso sensato y asequible. Invita a revisar el flujo completo hasta la persona que espera el resultado y preguntar por qué hace falta cada paso. Según su expectativa, algunos problemas pueden necesitar modelos más capaces, pero muchos podrían resolverse con modelos más baratos y buenas herramientas; también podrían desaparecer tramos enteros del proceso. Cierra invitando a comentar cómo se ahorran tokens y procesos sin reducir el uso de IA.

Transcripción completa
[0:00] agents keep getting better and better and better, but they can still make your bill go up. At Dreamforce, I got to ask Mark Beni off a question about how we get more people to adopt AI. And later that day, I was on a panel talking about the cost that we're all facing when we roll out agents of scale. By the end, you're going to know how to look at your own workflows and ask which work should still exist before you end up effectively paying rent for all of these agents. I'm excited about this one because I want people to be able to use
[0:32] agents that are bigger. I want them to be able to do more ambitious work without feeling like they're carrying the burden of a massive financial question mark when they set up AI. We're finally getting to the point where we have that capability. Now, we have a chance right now to rethink how jobs get done, how work gets done, and ultimately we have a chance to make the capability to do that kind of ambitious work with AI affordable for companies of all sizes. So stay with me because the most interesting part of the Dreamforce
[1:02] conversation, at least to me, was what happens when you go back to the business outcome, when you wipe the whiteboard clean and give yourself permission to change how work gets done to get to the same business value you've been looking to achieve all along. >> The changes that you build, the model that you need, what you're paying for, all of that comes back and reasons back from the business value. This year, Dario Amade, Sam Alman, Jensen Hong, and others all shared the keynote stage and they talked about AI safety. They talked
[1:33] about growth, they talked about models, they talked about adoption, they talked about how to get AI in more people's hands safely. So, let me start with that adoption question. I was at the media Q&A and I asked Mark how he thought about getting different kinds of people to use Agent Force and really the question on a lot of our minds which is how do we help broad swaths of companies actually get excited about get passionate about and start adopting AI in ways that are useful. You have the early adopters already, right? You've got the people in the middle who will
[2:03] probably use Chad GPT a bit here and there and then you've got people who would really frankly prefer not to be using AI or don't understand why it's valuable or maybe they're going to fight changing the software. Every company of any reasonable size has these three kinds of people. So when Mark answered the question, the part of his answer that really interested me was how he pivoted back to the interface and how interfaces are changing in the age of AI. When you get agents into a tool like Slack, for instance, you're getting it
[2:33] into the places where people already work. And I thought that was really perceptive because we spend a ton of time in AI assuming that the person on the other side is excited to discover a new product. But most of us have a job. We have a customer waiting. We have something we need to get out the door. We have no time left. If the AI can help get us where we need to go, right in the moment, where we are inside the work that we're already doing, then you've
[3:04] removed a giant reason to not try AI. Now, that does sound like a product detail. I get that it sounds small, but follow it through. Someone tries an agent because it's already there. Maybe it's living in Slack. It handles something useful. Well, now why don't you try it again? It kept a small promise for you. Try it again. And this time, you might ask for a little bit more. You might get a little bit bolder. Your colleague sees it. Your manager wants to know whether the whole team is going to be able to use it. And this is
[3:35] how you start to change. This is how you start to move beyond a little group of people who are going to find every new model anyway, right? the 5% and this is how you get into the whole company and that was the larger shift I was trying to understand at Dreamforce. I don't mean that every enterprise has immediately figured this out because they have Slack. We're all going on this journey together. But in the conversations I've been having, we're getting into what happens when people start to go from agents are a novelty to
[4:07] agents are reliable. Agents are trustworthy. Agents are something you can depend on. [clears throat] How do you make that work reliable? How do you connect it into the company's actual information? How do you pay for it when a successful experiment becomes something a ton of people now want to use every day? So after the Q&A, I was on a panel hosted by Jes, the EVP of Agent Force at Salesforce, and we were talking together. There were folks from PWC and Pepsi there as well talking about AI implementation. My job was just to talk set macro context and the
[4:38] context I gave starts back in January. That's the point I keep coming back to this year when I think about how models have become so much more capable. Capable enough that a whole bunch of product work has suddenly looked really practical. A whole bunch of business work has suddenly looked really practical. You can give a model tools and it can use them extremely reliably. You can give it information. it can do something with it. Notice it needs another piece. Keep going. And unlike
[5:09] 2025, 2024, you don't have to break everything into tiny questions. You don't have to sit there kind of lugging the answer, copy paste hell from one place to another. And once that begins to work, of course, people use it more. That's natural, right? So, continuing the story, we wanted adoption. useful models give people a reason to adopt. But that same capability that unlocked for all of us in January changes the size of the job. You used to ask for an
[5:40] answer. Now you're asking the agent to investigate a customer problem, to look through an account, to find relevant history, to check product information, and to come back with something that you can act on. The agent may make a whole series of model calls along the way, right? It's not going to be just one thing. It reads more. It uses more tools. It follows up on what it finds. There's way more work inside that one request. Now, 100x a,000x more tokens. So, you have more agents running and now
[6:11] you have way, way more tokens per run. And those things double multiply, don't they? Just to make the relationship really obvious, imagine 10 times as many runs with, you know, 100 times as many tokens per run. you're you're already at a thousandx just there. [clears throat] >> And those are kind of madeup numbers, but they're kind of not when you look at actual token consumption. You can get to a very large increase very quickly without anyone doing anything particularly strange in the middle of 2026. So, we're using a system that got
[6:44] better and the costs add up, right? There are frontier models right now that are charging $50 per million output tokens. output specifically just getting the tokens out input cached input those are all more prices over the top right but even if we don't dive into the pricing table and get lost there you can see that the problem with sending every little decision to the most expensive intelligence you can buy is that you can't control your costs long term and this is where to be very honest with you
[7:14] I start to get a little bit frustrated with where the conversation goes sometimes um because people will often paint it as oh the greedy engineers are using all the tokens. The greedy creators are using all the tokens. Okay, but what models are we giving them? How are we enabling them? If you want people to use AI, you want them to find better bigger things they can tackle and bigger things they can go after. Well, then we need to equip them with a system that sets them up to do that. Because if every ordinary request takes a really
[7:44] expensive route through a really complicated system, that's a decision. That's a design decision that someone made about the AI harness and infrastructure. So you can't hand that large decision, that giant design, that setting to a person and then act surprised when they adopt AI and it suddenly costs you the company money. And I want to stay with that for a minute because the obvious response is to go shopping for a cheaper model. And there's a ton of value in that. We talked about that a lot on the panel actually. But before you decide which
[8:17] model should do the work, I want to know why we're doing the work in the first place. This was a point I made on the panel. And that's where the conversation got a lot more interesting. Think about the old inter office envelope. Maybe for some of you, you've never seen an interoffice envelope. The white hairs are showing here. Uh but there was a little interoffice envelope. It had brown uh sort of a brown envelope with a little bit of string that wraps around two little circles. Someone puts a document in it. They write their name on the front. They send it to another department. This really happened, guys,
[8:47] for those of you who are younger. Uh the person opens it. They do their part of the document processing. They cross out their name and they send it down to the next department. By the time it gets back to you, the front of the envelope is like a history of process in the company. Now, picture that same process on the screen. The envelope became an email, then it became a ticket. Somebody still has to summarize what the previous person said, put it into the format the next team expects and explain why it
[9:17] matters. Now, there may be very, very good reasons why those steps exist, but some of them exist because at the time that the process was designed, the people or the systems couldn't share what they needed any other way. Now, fast forward to 2026. You can put an agent in every one of those places. An agent can read the request. An agent can reformat the request. An agent can
[9:47] prepare the handoff. An agent can check the handoff. And it looks incredibly modern, doesn't it? There's AI everywhere in your company all of a sudden. But here's the kicker. You still may be passing the same envelope around the building. You're just doing it with agents. You've made each stop faster without asking why the envelope has to visit all of those desks along the way. This is what I was getting at in the panel when I talked about starting with a blank sheet of paper. That's what I
[10:18] meant. If you run a business, your job is to go back to the handful of things that actually create value. I tend to think in terms of like five to eight major value streams at the CEO level. And your business might divide them up differently. But what I'm looking at is what is the complete path by which you win a customer or deliver what you sold or keep that customer or collect the money. Right? Ring the cash register. Start there and ask what has to happen
[10:48] for that result to be extraordinary, really good. And give yourself permission to start with that great result you want and draw the right path to get there. And it may be a very different path from where you're at today. Because if you start with every department's existing process, every old handoff is going to show up from one of your teams as, "Oh, it's a new requirement." And in that situation, nobody's going to argue to delete it. It's already on the page and everyone's going to be talking about the wrong thing, which is hiring
[11:19] the agent to perform the job as it was inherited. So, let's make this concrete with a customer asking for a quote. now is an imagined example, but it's one I've certainly lived and a lot of other folks have lived. The request comes in, somebody summarizes it for sales ops, somebody checks the account, somebody translates it into a product configuration, somebody puts that information into the pricing system. Then the quote goes back through all those people who need to see it, right? And maybe product eventually signs off
[11:49] on it. That's where I was. And the customer eventually gets an answer. Well, what did we need at the end? We needed the customer to get an accurate quote that we're authorized to offer. We needed the company to have a record that that quote was generated. And we needed to ask about anything that we could not resolve along the way. And those are real requirements. But the summary that only existed because one team couldn't read the other team's system, that kind of work doesn't have a job anymore. So
[12:20] if you go through that process, the challenge is to ask yourself what does that final quote look like and then how can we get to that final quote tackling the complexity we need to tackle with a minimum of handoffs. You can drop traditional enterprise steps out entirely because the reason for those steps has gone. You never spend the tokens on them at all. Zero is the best cost, isn't it? And notice what else changes. The agent
[12:52] doesn't have to read a summary that we didn't produce. It doesn't have to ask another agent what that summary meant. Like there's so many fewer points of failure here. It doesn't have to reconcile multiple versions of the same request that drifted as they moved through different departments with all these different agent interactions. So the workflow itself can get shorter. You get to use the model's ability to understand the whole problem instead of asking it to reenact every single handoff people used to make like a bunch
[13:23] of theater kind of going along. And that this is why we need business people involved in agent design systems. An engineer can make the step cheaper absolutely and they can build a really great agent to perform whatever work is needed. But the engineer may not have the authority to say that sales ops no longer needs that particular document. Somebody who owns the business result has to be able to have that conversation across departments and say I want
[13:53] simplicity. I want this to be easier. >> Otherwise, every department gets a faster version of its own process and the customer is still waiting for the envelope to come back and we're just passing it around the building, right? But we're doing it with agents and calling it progress. Of course, the discount approval doesn't disappear just because the AI is smart. The price still has to be right, right? You still need a record of what you offered. Looking at the whole process lets you separate out all of those particular requirements
[14:24] from the admin work that kind of grew up like coral kind of accumulating and growing into a reef around the actual value. And when you remove some of that admin work, you know what's great about it? It's good for us as people. The team gets time back. Whether that becomes more sales or or better service or a less overloaded team, it's going to depend on what you do with the time. But it's worth trying for. It doesn't mean it's an automatic reduction in payroll or anything dramatic like that. In fact, I had another conversation at Dreamforce
[14:54] that helped connect the dots on this for me. I spoke with Rohan Kumar, Salesforce's president and chief platform and engineering officer about what he's been seeing as he's actually been rolling out agents with customers, talking about a lot of what we've just been talking about in this video. One of the things we both really resonated with was the idea that what do you do with AI once you're past the AI can do my email stage? People have tried the email assistant. They've had the experience of
[15:24] getting to draft faster with whatever tool they have, co-pilot. Right now, they want to know what comes next. And his emphasis is really been around building with specific customers and the work that they actually need to get done. How do we embed with them, right? How can Salesforce dig in with them, figure out what's working, and figure out how to scale? He's also been thinking a lot about how you debottleneck product and technical work, which I love nerding out on. Um because think about it, if you run an
[15:54] engineering org, if AI helps you produce code faster, you're still going to have to merge it. You're still going to have to check it. You're still going to have to get it deployed in ways that yes, customers can use. And speeding up one of those activities doesn't mean that your whole org can suddenly move at that speed. You have to be really thoughtful and logical about getting faster. You have to follow the work far enough to see where it gets stuck next. The value of an agent isn't exhausted by making the existing activity faster. If it
[16:27] changes what one system can understand and do, it should give you a reason to reconsider the rest of your process, which is exactly kind of where Rohan and I were talking back and forth. And I think that's a much more serious conversation. It's a much more demanding conversation for companies than just buying access to a better model. But it's also a much more fruitful conversation. It means looking at work that people are used to doing and asking whether that work is just busy work now. And once you've done that, thinking
[16:58] through your model choice starts to make a lot more sense because the remaining work is not all equally difficult. Some of it is a calculation with a known rule. Some of it is interpreting what the customer meant. And some of it is a messy exception, right? where the information conflicts and somebody needs to investigate. There's an edge case involved. Why? Why would we expect all of the different use cases I just described to need the same amount of
[17:28] intelligence? They don't. They don't. And this came up in my conversation with the head of agent forces engineering JSH as well. There's this continuum of work between where the answer follows a rule, where it's relatively deterministic and where the work may need interpretation, where it might be more probabilistic. When people first get excited about AI, they tend to push everything into the model and hey, it's amazing. It's miraculous. It's fantastic. It generates
[17:59] tokens. Let's have it do all the things, right? But a model can do all of those things and it can actually be incorrect if you're not basing it on the right data. A model can be more correct cheaper with an open-source open weights option if it's calling the right data. If you're able to just use the model to coordinate work to call ordinary software like a CRM to do all of the parts that are already settled, you can
[18:29] save tokens. you can get more predictable work at the same time. And in the quote example we talked about, a pricing tool could apply pricing rules and you wouldn't have to use an LLM to get probabilistic pricing. The model doesn't need to rediscover arithmetic in that case, right? And all the model may need to do is understand the customer's language well enough to identify the product, recognize what's missing, and explain the answer that was derived from a tool call back to the to the CRM. And
[19:00] for a lot of routine enterprise work, the amount of intelligence required to do that kind of job, you don't need to worry about the frontier models anymore. We're we're so far past that. If you can solve a, you know, millennium prize problem like Navier Stokes, you are well past the intelligence level you need to update your CRM. you are well past needing to figure out which model to use to figure out what products someone mentioned in an email.
[19:30] You need a model that does that job reliably with the right information, the right tools around it. And I'm so excited. I'm I'm excited about the fancy models, right? I'm excited about models that can help with extraordinary scientific problems. I believe we are early on the intelligence curve. There's a lot of good intelligent work to be discovered up ahead. I just don't need to pay for that level of capability every time a customer asks an ordinary business question. That's why good openweight models are so interesting to
[20:00] me along with cheaper hosted models because there's a lot of work where a less expensive model set up well is just frankly enough. Open weights aren't automatically cheaper to operate and a small model isn't automatically the right one, but often times that's the case. the opportunity is there to fit the system to a task whose requirements you actually understand. And so I think we need to stop asking ourselves which
[20:30] model wins everything. I think that's the wrong question. That's a 2025 question. We need to start asking which model can do this job well. On the panel, JS responded to the blank sheet and the model routing ideas by talking about classifiers and evals. Everyone's favorite subject, right? A classifier is the part of the system that recognizes what kind of request has arrived and sends it to the appropriate place. This is how you actually make the distinction
[21:00] I'm talking about. We just talked about making this useful in practice. The standard customer request would be classified and sent to an open weights model. the unusual case, the edge case where the facts don't fit or the consequences require more care. That goes to a fancier model, doesn't it? My ambition here is to reserve the frontier model for the hardest problems. That's where a lot of us think this is going. And and in that situation, we want workflows and classifiers that allow us
[21:31] to support that reliably. In fact, we may put the smart model in the classifier just to do that. And that's something to work on. That's something to test on. It's not like finding 99% of the enterprise work is easy. It's actually quite challenging because it has to be the right 99%. But if you can identify the ordinary work reliably, you can give a lot of people access to super useful intelligence at a very very different cost than we assume AI costs. It becomes
[22:02] transformative. And then the expensive model is absolutely there when the job calls for it. There there is a catch here though and this is a big part of what we discussed. You can't assume that the setup around the model should stay the same when you change the model. We were talking about thin harnesses and thick harnesses on the panel. Now the harness is and Jo advocated for this. I I fully agree. It's the whole arrangement around the model. It's not it's not a narrow
[22:33] definition of harness. It's a rich definition of harness. The instructions, the tools, the information it can use, the checks, the way it moves through a job. A less capable model often needs more of that harness structure to do its job predictably. And when you think about the quote example, you may end up giving that entire model a very specific job. Identify the product, the quantity, what the customer hasn't told us. The software is able to deterministically check what fields in the CRM are present. It's able to call a pricing
[23:03] tool. It's able to enforce an approval requirement. The model has useful work to do there, but the surrounding system has to have a harness that makes the path to that data really really clear. It frankly it implies a thicker harness >> and the thickness comes from structure. It doesn't have to mean a gigantic pro. Whereas if you're going on that difficult exception, that 5% that 1% of cases, I want to give the frontier model freedom. And I found this by experience
[23:33] working with frontier models myself. If you have a challenging problem for it, you don't want to limit it. You want to be able to say, "Here's the customer problem. Here's the evidence. Here are a few tools, general purpose tools. Here's what a good result has to satisfy. Now, please work through it. Figure it out." And that's a thin harness, right? If I force the model to follow every little reasoning step I wrote for a weaker model, I get in the way of the IQ points I'm paying for. So, I want a thinner
[24:03] harness around the smart model doing investigative work, while I want lots of like structure, a good thick harness around the open weights model that I'm using at scale to run my business process. Ultimately, the setup needs to evolve with the model, just as the business process needs to evolve with what the system can do. Today, if you want to get into the everyday token waste inside a setup like that, I've put together 15 different changes and a token saver skill guide on the Substack
[24:35] going with this video. And it goes beyond what I can cover here. It covers things like carrying forward the accepted result and selecting the information the model needs. uh and really the dream force conversation pushed me to think about the same problem at the scale of the business process. How much work are we carrying forward simply because it's what the old system needed. And this is where eval becomes a part of the larger story. You can't you can't tell whether a redesigned process works just because
[25:05] the agent sounds pleased with itself. Really, you can't always tell just because the human is happy. You can't tell when the cheaper model's worth it because it produced something that looked approximately right. You have to actually know. You have to actually know. And one of the metaphors I loved about EVELs, it came out of the panel discussion was this idea that we as humans all have annual evaluations at work, right? We evaluate people. We ask whether they've done their job well. Why
[25:35] would we give an agent real responsibility in the company and never evaluate it? We would, right? Obviously, an agent doing thousands of jobs needs feedback much more often than once a year. But regardless of the metaphor you use, that idea, the idea of evaluating an agent needs to become familiar to you. It's an important part of what we're talking about here. The agent has a job and we need to find a way to know whether it did that job well. And with the quote example, we've been following
[26:06] through. That means checking that the actual price is correct against the pricing system, checking that the approval happened, checking that the record changed. It also means recognizing when asking the customer a question was the right next action even though the quote wasn't finished yet, which is a little bit more of a complicated use case. And yes, some parts will need judgment, too. Did the explanation actually address what the customer was worried about? someone who knows the work has to help define the
[26:36] eval in that situation. That's super normal. A a technically valid document, does that actually contain the right answer or is it technically valid and still incorrect? And this is why I keep saying eval are a human skill as much as an agent skill. In fact, I think one of the most important things that we can do is teach people how to write evals. It's such a scalable skill in 2026
[27:06] because the agent has to be able to use those checks, those eval to learn when something didn't work to make a useful correction. If it's missing information, it needs to know what's missing. If the work is complete, it should know it's complete. Otherwise, you end up paying for a very long run and you don't even know what's worth it, right? You don't know if it's valuable. So wrapping it all up, by the time I was putting my notes together, you know, after the first day or so of Dreamforce, the cost conversation ended up being connected to a much larger story for me. Ultimately,
[27:38] models have gotten useful enough that more of us have wanted to start using them. They've gotten capable enough that they can run longer and do more. That's one of the big themes of the conference here this year. And now that same capability is giving us the chance to remove work and to redraw the path to a business result. So the consumption is growing in a two-fold way. More people, more agent tokens, but our response to it can compound as well. A shorter process leaves less work to pay for and
[28:10] matching the remaining work to the right model gives us that double savings and we can make the work cheaper. Again, I don't have a universal percentage to promise you because frankly, your business is going to have to figure this out for itself, but what I would suggest is look beyond the model build. Ultimately, if your team can serve more customers, if you can get them a correct answer sooner, if you can spend less time repairing handoffs, and those are pieces of real business value, right? Well, in that case, even if the AI bill ends up growing a bit because you're using AI so much, still perfectly
[28:41] reasonable, a ton of value there. Now, if the AI bill grew because six agents were writing reports nobody was reading, different situation. So, I want you to look beyond the token leaderboard. Both of the examples I just gave to you can look like lots of tokens on the dashboard. And this takes me all the way back to the beginning and to Mark's answer in Q&A about getting AI into the places that people already work. I want that to succeed. I want ordinary people to have access to these systems without feeling like every question is a
[29:11] financial mistake. But once we make agents easy to use, the people designing the systems have a responsibility to make that use sensible for the business. Give people tools that let them complete the job and then don't risk slap them when they use them. Give ordinary work an affordable path. Let the model spend its intelligence where understanding is actually required. That's the part of Dreamforce I want you to take back to your own work. The conversations I had were getting into what comes after that
[29:42] first useful experience, that aha moment with AI, after the email draft, right? After somebody tries an agent and says, "Okay, wow, this could actually help." That's when the old process becomes a choice you have to look at again. So, if you've got a workflow in front of you right now, I'm challenging you to look at it. Look all the way through to the person waiting for the results. Ask why each piece of work has to happen for that person to get what they need. You may find that the problem deserves a much more capable model, but I'm betting
[30:13] you, you're more likely to find that a cheaper model with good tools can handle it. And you may find that a whole stretch of work that you thought was essential to get the envelope onto the desk. Maybe it's maybe it's actually not. And now you have the ability to stop a bunch of those processes. So those are my takeaways from the first day or so of Dreamforce here. I'm excited to go back into it, continue having conversations, and I'd love to hear from you in the comments. What are you seeing at work with agents that
[30:44] allows you to save tokens, you to save process? How are you cutting your token bills, but still using AI more often? I'll see you next time.
