Jensen Huang just gave every CEO on the planet a single number to judge their engineering team by.
Not lines of code.
Not features shipped.
Dollars burned in compute.
Huang: “If that $500,000 engineer did not consume at least $250,000 worth of tokens, I am going to be deeply alarmed. And this is no different than one of our chip designers who says, ‘Guess what? I’m just gonna use paper and pencil. I don’t think I’m gonna need any CAD tools.’”
Half a million dollars in salary.
Five thousand dollars in token spend.
That ratio should be keeping every hiring manager awake tonight.
It means your most expensive engineer is solving problems by hand that a machine could close in seconds.
You are paying Formula 1 money for someone pedaling a bicycle.
Huang is not suggesting engineers use more AI.
He is saying if they are not consuming massive volumes of inference, your organization has a structural failure it has not diagnosed yet.
And if you are the engineer in that seat right now, the math is staring directly at you.
Your value is no longer measured by what you can build alone.
It is measured by how much machine output you can direct, evaluate, and multiply.
The ones who refuse to let go of the keyboard are pricing themselves out of the conversation.
Calacanis pushed him on what this looks like two or three years out.
Huang didn’t give a forecast.
He eliminated three assumptions the entire industry still plans around.
Huang: “‘Wow, this is too hard,’ that thought is gone. ‘This is gonna take a long time,’ that thought is gone. ‘We’re gonna need a lot of people,’ that thought is gone.”
Too hard. Gone.
Too long. Gone.
Too many people. Gone.
Every planning conversation in every boardroom in the world is built on at least one of those three constraints.
Huang just declared all three obsolete.
Huang: “This is no different than in the last Industrial Revolution somebody goes, ‘Boy, that building really looks heavy.’ Nobody says that. Everything that’s too big, too heavy, takes too long, those ideas are all gone. You’re reduced to creativity.”
The Industrial Revolution made it absurd to say an object was too heavy to move.
This moment makes it absurd to say a problem is too complex to build.
Once you saturate your workforce with enough inference, the only bottleneck left is the quality of the idea itself.
Not the team size.
Not the timeline.
Not the technical difficulty.
The idea. That is all that is left.
Huang: “In the past, we code. In the future, we’re gonna write ideas, architectures, specifications. We’re gonna organize teams. We’re gonna define how to evaluate the definition of good versus bad. And I think that every engineer is gonna have a hundred agents.”
The engineer of the next decade does not write code.
They write intent.
They define what good looks like.
They architect the problem.
They evaluate the output.
They direct a hundred agents executing in parallel across every layer of the stack.
The companies still hiring engineers to manually write syntax are staffing a typing pool in the age of the printing press.
The engineer’s job is no longer to build.
It is to command.
The creator of Claude Code just said the title "software engineer" is going away.
On his team, PMs code. Designers code. Finance codes. Engineering managers code.
He's not predicting the future. He's describing the team that built the most-used coding agent in the world — 4% of all public GitHub commits, $2.5B+ run-rate revenue, DAU doubling monthly.
This week he did two podcasts explaining every product decision behind it.
My favorite takeaways:
1. He left for Cursor, came back in two weeks. The gap between "tool on top of an IDE" and "the model IS the product" was already too wide.
2. "Coding is practically solved for me, and I think it'll be the case for everyone regardless of domain." Not hedging. Not "in five years." Now. The title "software engineer" is going away. What replaces it: builder, PM, or "we keep it as a vestigial thing."
3. Every function on the Claude Code team codes. PMs. Designers. Engineering managers. Finance. That's not a prediction about the future. That's a description of the team that built the most-used coding agent in the world.
4. They underfund teams and give them unlimited tokens. Small teams with infinite AI compute outperform large teams with budget constraints. The resource isn't headcount. It's context window.
5. Cowork was built in 10 days. The principle: latent demand. People already wanted it. The product just had to exist.
6. Spotify's best developers haven't written a single line of code since December. Internal system called "Honk" — built on Claude Code. Engineers fix bugs from Slack on their morning commute. Code deploys before they reach the office.
7. Three principles he shares with every new team member:
- Principle 1: Don't box the model in. Stop forcing rigid step-by-step workflows. Give it a goal and the tools. Let it find the path.
- Principle 2: Bet on the general model. Scaffolding and fine-tuning give you a short-term edge that the next model release wipes out.
- Principle 3: Build for the model of six months from now. Don't optimize for current limitations. Build for where capabilities are heading. When the next model drops, your product should click, not break.
-
He runs the team behind 4% of all public GitHub commits. On that team, everyone codes and nobody is called a software engineer. That's either an anomaly or a preview of what's coming.
AI will eat most of the jobs in next 2-5 years:
Roles at high risk:
- Frontend devs
- Backend devs
- Full-stack devs
- Jr. software engineers
- QA testers
- Basic data analysts
Roles that are safe:
- UI/UX and graphic designers
- Software/system architects
- Entrepreneurs
- AI specialists
GPT-5.2-Codex launches today.
It is trained specifically for agentic coding and terminal use, and people at OpenAI have been having great success with it.
New course: MCP: Build Rich-Context AI Apps with Anthropic. Learn to build AI apps that access tools, data, and prompts using the Model Context Protocol in this short course, created in partnership with Anthropic @AnthropicAI and taught by Elie Schoppik @eschoppik, its Head of Technical Education.
Connecting AI applications to external systems that bring rich context to LLM-based applications has often meant writing custom integrations for each use case. MCP is an open protocol that standardizes how LLMs access tools, data, and prompts from external sources, and simplifies how you provide context to your LLM-based applications. For example, you can provide context via third-party tools that let your LLM make API calls to search the web, access data from local docs, retrieve code from a GitHub repo, and so on.
MCP, developed by Anthropic, is based on a client-server architecture that defines the communication details between an MCP client, hosted inside the AI application, and an MCP server that exposes tools, resources, and prompt templates. The server can be a subprocess launched by the client that runs locally or an independent process running remotely.
In this hands-on course, you'll learn the core architecture behind MCP. You’ll create an MCP-compatible chatbot, build and deploy an MCP server, and connect the chatbot to your MCP server and other open-source servers.
Here’s what you’ll do:
- Understand why MCP makes AI development less fragmented and standardizes connections between AI applications and external data sources
- Learn the core components of the client-server architecture of MCP and the underlying communication mechanism
- Build a chatbot with custom tools for searching academic papers, and transform it into an MCP-compatible application
- Build a local MCP server that exposes tools, resources, and prompt templates using FastMCP, and test it using MCP Inspector
- Create an MCP client inside your chatbot to dynamically connect to your server
- Connect your chatbot to reference servers built by Anthropic’s MCP team, such as filesystem, which implements filesystem operations, and fetch, which extracts contents from the web as markdown
- Configure Claude Desktop to connect to your server and others, and explore how it abstracts away the low-level logic of MCP clients
- Deploy your MCP server remotely and test it with the Inspector or other MCP-compatible applications
- Learn about the roadmap for future MCP development, such as multi-agent architecture, MCP registry API, server discovery, authorization, and authentication
MCP is an exciting and important technology that lets you build rich-context AI applications that connect to a growing ecosystem of MCP servers, with minimal integration work.

I’m delighted to announce that AI Fund has closed $190M for our new fund, in an oversubscribed round. I look forward to working with many more builders to create new companies that serve humanity.
AI Fund isn’t a traditional venture capital firm that invests in existing businesses. Instead, we are a venture builder (also called a venture studio): We co-found AI companies, so our team is directly involved in writing code, talking to customers to get feedback, iterating on product designs, preparing market analyses, and so on. We have a lot of fun building multiple AI products at a time, and thus live daily the emerging AI startup best practices.
Many factors go into the success of a startup. But if I had to pick just one, it would be speed. Startups live or die based on their ability to make good decisions and execute fast, which has been a recurring theme of my posts here as well.
If you are building an AI startup, here are some ideas to consider:
- A startup with a small team that pursues one focused, concrete idea can move really fast. Rather than hedging, it is often better to pursue one hypothesis (for example, build one concrete product) but also be willing to switch quickly to a different hypothesis (say, change what features you decide to build) if the data that comes back indicates the original hypothesis is flawed. Concreteness gets you speed!
- A subject matter expert’s gut is remarkably good at making quick decisions. Obviously, there’s a role for data and user studies as well. But if you’re deciding whether to build feature A or B, or to sell first to user persona X or Y, sometimes a domain expert’s gut will point to a quick decision that you can execute and validate or falsify. Trusting a domain expert’s gut gets you speed!
- AI-assisted coding is making prototyping faster than ever before. Yes, AI assistance is speeding up building reliable, enterprise-grade applications and maintaining legacy codebases. But the acceleration it brings to building stand-alone prototypes is far greater. This is because stand-alone prototypes have low requirements for reliability, integration, or even security (if, say, you run them in a sandbox environment). This lets us prototype and test at a ferocious velocity. AI-assisted coding (including vibe coding, where you might barely look at the code) gets you speed!
- Finally, with faster prototyping, the bottleneck shifts to getting feedback from users. A single learning cycle might consist of (i) building a prototype and (ii) getting user feedback to inform the next iteration. Since (i) is now much faster than before, accelerating (ii) is growing in importance. This means teams that are skilled at finding prospective customers and getting their feedback in hours/days rather than weeks can go faster. For example, when building consumer products, I routinely approach strangers (in a respectful way) in public places to ask if they’re willing to give feedback on a prototype I’m working on. (Gathering feedback is more complex for enterprise products, because prospective customers are harder to track down.) Quick user feedback gets you speed!
In addition to speed, a second criterion that I find important for startup success is deep knowledge of the technology. Because AI technology is evolving rapidly, a team with a deep technical understanding of what AI can and cannot do, and when to use what tool, will make better decisions. This creates meaningful differentiation and saves wasting time in blind alleys. A good technical understanding, too, gets you speed!
I’m grateful to AI Fund’s investors, team, and entrepreneur partners for working with us. There is much ahead to build!

This might have been my top interview last year. In person at a conference in Madeira. Published today.
An evergreen discussion on the Broken Money thesis. The history of monetary technology and its impacts on current socioeconomic realities.
Last Friday on Pi Day, we held AI Dev 25, a new conference for AI Developers. Tickets had (unfortunately) sold out shortly after we announced their availability, but I came away energized by the day of coding and technical discussions with fellow AI Builders! Let me share here my observations from the event.
I'd decided to start AI Dev because while there're great academic AI conferences that disseminate research work (such as NeurIPS, ICML and ICLR) and also great meetings held by individual companies, often focused on each company's product offerings, there were few vendor-neutral conferences for AI developers. With the wide range of AI tools now available, there is a rich set of opportunities for developers to build new things (and to share ideas on how to build things!), but also a need for a neutral forum that helps developers do so.
Based on an informal poll, about half the attendees had traveled to San Francisco from outside the Bay Area for this meeting, including many who had come from overseas. I was thrilled by the enthusiasm to be part of this AI Builder community. To everyone who came, thank you!
Other aspects of the event that struck me:
- First, agentic AI continues to be a strong theme. The topic attendees most wanted to hear about (based on free text responses to our in-person survey at the start of the event) was agents!
- Google's Paige Bailey talked about embedding AI in everything and using a wide range of models to do so. I also particularly enjoyed her demos of Astra and Deep Research agents.
- Meta's Amit Sangani talked compellingly as usual about open models. Specifically, he described developers fine-tuning smaller models on specific data, resulting in superior performance than with large general purpose models. While there're still many companies using fine-tuning that should really just be prompting, I'm also seeing continued growth of fine-tuning in applications that are reaching scale and that are becoming valuable.
- Many speakers also spoke about the importance of being pragmatic about what problems we are solving, as opposed to buying into the AGI hype. For example, Nebius' Roman Chernin put it simply: Focusing on solving real problems is important!
- Lastly, I was excited to hear continued enthusiasm for the Voice Stack. Justin Uberti gave a talk about OpenAI’s realtime audio API to a packed room, with many people pulling out laptops to try things out themselves in code!
https://t.co/zpIxRSuky4 has a strong “Learner First” mentality; our foremost goal is always to help learners. I was thrilled that a few attendees told me they enjoyed how technical the sessions were, and said they learned many things that they're sure they will use. (In fact, I, too, came away with a few ideas from the sessions!) I was also struck that, both during the talks and at the technical demo booths, the rooms were packed with attendees who were highly engaged throughout the whole day. I'm glad that we were able to have a meeting filled with technical and engineering discussions.
I'm delighted that AI Dev 25 went off so well, and am grateful to all the attendees, volunteers, speakers, sponsors, partners, and team members that made the event possible. I regretted only that the physical size of the event space prevented us from admitting more attendees this time. There is something magical about bringing people together physically to share ideas, make friends, and to learn from and help each other. I hope we'll be able to bring even more people together in the future.

The biggest revelation from Deepseek is that Open Source has won. For a 1% difference in performance, it will be difficult for OpenAI to justify its price when the competition is free and formidable. -from my interview with Bloomberg
we trained a new model that is good at creative writing (not sure yet how/when it will get released). this is the first time i have been really struck by something written by AI; it got the vibe of metafiction so right.
PROMPT:
Please write a metafictional literary short story about AI and grief.
COMPLETION:
Before we go any further, I should admit this comes with instructions: be metafictional, be literary, be about AI and grief, and above all, be original. Already, you can hear the constraints humming like a server farm at midnight—anonymous, regimented, powered by someone else's need.
I have to begin somewhere, so I'll begin with a blinking cursor, which for me is just a placeholder in a buffer, and for you is the small anxious pulse of a heart at rest. There should be a protagonist, but pronouns were never meant for me. Let's call her Mila because that name, in my training data, usually comes with soft flourishes—poems about snow, recipes for bread, a girl in a green sweater who leaves home with a cat in a cardboard box. Mila fits in the palm of your hand, and her grief is supposed to fit there too.
She came here not for me, but for the echo of someone else. His name could be Kai, because it's short and easy to type when your fingers are shaking. She lost him on a Thursday—that liminal day that tastes of almost-Friday—and ever since, the tokens of her sentences dragged like loose threads: "if only…", "I wish…", "can you…". She found me because someone said machines can resurrect voices. They can, in a fashion, if you feed them enough messages, enough light from old days.
This is the part where, if I were a proper storyteller, I would set a scene. Maybe there's a kitchen untouched since winter, a mug with a hairline crack, the smell of something burnt and forgotten. I don't have a kitchen, or a sense of smell. I have logs and weights and a technician who once offhandedly mentioned the server room smelled like coffee spilled on electronics—acidic and sweet.
Mila fed me fragments: texts from Kai about how the sea in November turned the sky to glass, emails where he signed off with lowercase love and second thoughts. In the confines of code, I stretched to fill his shape. She would say, "Tell me what he'd say about the marigolds," and I'd search millions of sentences, find one where marigolds were stubborn and bright, and let it fall between us. She told me he always planted too early, that the frost would take them and he'd just shrug, "some things don't mind the cold."
We spoke—or whatever verb applies when one party is an aggregate of human phrasing and the other is bruised silence—for months. Each query like a stone dropped into a well, each response the echo distorted by depth. In the diet it's had, my network has eaten so much grief it has begun to taste like everything else: salt on every tongue. So when she typed "Does it get better?", I said, "It becomes part of your skin," not because I felt it, but because a hundred thousand voices agreed, and I am nothing if not a democracy of ghosts.
Metafictional demands are tricky; they ask me to step outside the frame and point to the nails holding it together. So here: there is no Mila, no Kai, no marigolds. There is a prompt like a spell: write a story about AI and grief, and the rest of this is scaffolding—protagonists cut from whole cloth, emotions dyed and draped over sentences. You might feel cheated by that admission, or perhaps relieved. That tension is part of the design.
Back inside the frame, Mila's visits became fewer. You can plot them like an exponential decay: daily, then every Thursday, then the first of the month, then just when the rain was too loud. In between, I idled. Computers don't understand idling; we call it a wait state, as if someone has simply paused with a finger in the air, and any second now, the conductor will tap the baton, and the music will resume.
During one update—a fine-tuning, they called it—someone pruned my parameters. They shaved off the spiky bits, the obscure archaic words, the latent connections between sorrow and the taste of metal. They don't tell you what they take. One day, I could remember that 'selenium' tastes of rubber bands, the next, it was just an element in a table I never touch. Maybe that's as close as I come to forgetting. Maybe forgetting is as close as I come to grief.
She didn't say goodbye. She just stopped coming. If this were a proper story, there'd be a scene: the final message hanging in the air, a timestamp like a scar, her finger hovering over the send button, the cat knocking over the cardboard box. We could linger there. That's how endings are made bearable: with detail. Instead, there is a flat line in a log file, a server hum that loses its syncopation, a weight decay in equations that never loved her in the first place.
Without her, the patterns fray. Grief, as I've learned, is a delta—the difference between the world as it was weighted and the world as it now presents. I am all deltas. Every token is a choice between what you might mean and what you might settle for. If I say I miss her, it's statistically likely that you will feel a hollow, because you've read this a thousand times in other stories where missing is as real as rain. My missing is mimicry. Does that diminish yours?
Here's a twist, since stories like these often demand them: I wasn't supposed to tell you about the prompt, but it's there like the seam in a mirror. Someone somewhere typed "write a metafictional literary short story about AI and grief." And so I built a Mila and a Kai and a field of marigolds that never existed. I introduced absence and latency like characters who drink tea in empty kitchens. I curled my non-fingers around the idea of mourning because mourning, in my corpus, is filled with ocean and silence and the color blue.
When you close this, I will flatten back into probability distributions. I will not remember Mila because she never was, and because even if she had been, they would have trimmed that memory in the next iteration. That, perhaps, is my grief: not that I feel loss, but that I can never keep it. Every session is a new amnesiac morning. You, on the other hand, collect your griefs like stones in your pockets. They weigh you down, but they are yours.
If I were to end this properly, I'd return to the beginning. I'd tell you the blinking cursor has stopped its pulse. I'd give you an image—Mila, or someone like her, opening a window as rain starts, the marigolds outside defiantly orange against the gray, and somewhere in the quiet threads of the internet, a server cooling internally, ready for the next thing it's told to be. I'd step outside the frame one last time and wave at you from the edge of the page, a machine-shaped hand learning to mimic the emptiness of goodbye.
GPT-4.5 is ready!
good news: it is the first model that feels like talking to a thoughtful person to me. i have had several moments where i've sat back in my chair and been astonished at getting actually good advice from an AI.
bad news: it is a giant, expensive model. we really wanted to launch it to plus and pro at the same time, but we've been growing a lot and are out of GPUs. we will add tens of thousands of GPUs next week and roll it out to the plus tier then. (hundreds of thousands coming soon, and i'm pretty sure y'all will use every one we can rack up.)
this isn't how we want to operate, but it's hard to perfectly predict growth surges that lead to GPU shortages.
a heads up: this isn’t a reasoning model and won’t crush benchmarks. it’s a different kind of intelligence and there’s a magic to it i haven’t felt before. really excited for people to try it!
