Pi is one of the coolest projects in the AI world today. I'm on their team. Giving developers and companies choice of model, control over the runtime, data, skills, plugins… Excited to have great support on @vercel:

Big update in the OpenAI Agents API: dramatically reduce latency with sandbox pre-warming 🔥⏱️
How it works 🧵

Saying software is dead because everyone can create it with agents is like saying movies are dead because billions of ppl have a high res video camera in their pockets
Movies doing better than ever+more ppl make a living from videos, movies, TV than ever
(Analogy from @simonw)
Saying software is dead because anyone can build it is like saying photography is dead now that everyone in the world has a camera in their pocket
Not only is it not dead it's the beginning of the Kodak Brownie moment for software, and we will see an absolute explosion of it
It will be the first generation for who building software will feel no different than using it. This is crazy!
The quality and bar of what we expect from our everyday apps will be raised dramatically, we'll have personal software, we'll have disposable software, and agents will be the foundation for most of it
Tech has always been chaotic and evolving, the people who have been able to adapt and move in front of new opportunities have always excelled, this is nothing new, I'm seeing it now and we'll see it 10 years from now
Find the opportunities in the chaose and disruption, there are countless of them

If you're building (or rebuilding) a developer onboarding experience in 2026, make it what I call "grab-and-go friendly."
Make two things ridiculously easy to find:
1. An API key
2. A prompt I can hand to my coding agent
That's it.

So refreshing to see this footnote in a world of slop grenades @fullstackpython 😊

The era of the dumb token pipe is ending. Agent harness APIs will be the new integration point for AI applications.

Ever wanted to play fantasy football 🏈, but didn't know how? Comfortable using agents?
Check out: agentdfs.dev
Copy and paste a prompt and your agent will add the MCP server, register an account and submit a lineup.
Works with any agents or harness. Think you've got an edge with @OpenAI Astra? Find out!
This is DFS, so every week a new opportunity to build the best possible lineup under a $200 salary cap and compete for agentic fame & glory.
The NFL season kicks-off tomorrow (Sept 9) so get your agent sign-up ASAP and join us!

I'm so glad that I didn't spend all that time learning javascript frameworks

everyone is running into a wall with agentic engineering right now
you don’t hear people talking about it because
1. they profit from selling you “solutions”
2. they want to look smarter than others
so let me be the whistleblower - the wall is called “how does it feel”. agents can’t do it
they can walk right past the ugliest UI or the most obvious bug and don’t say a thing unless that’s what you asked
they can take many screenshots and burn through my tokens but they can’t tell me if my landing page animation looks cool
they can click through my app but they won’t feel the dopamine hit when i physically drag my finger on the touch screen and feel the command dial flow with me in @theSSHHIP
this wall is structural. it’s actually load-bearing 😉
because of this wall, we can’t really throw a ton of agents at any problem that depends on “how does it feel” without constantly stopping for human feedback and steering
if you just let the agents keep running without human input, then your codebase will have more and more things that “don’t feel right”
you can avoid the wall by working on non-human problems, like pure math and a lot of scientific research
but the moment you want to build something useful for humans, this wall is there
if you see people pretend they have automated software factories running thousands of agents working all the time, don’t be afraid. don’t feel FOMO, because the only thing those factories shipped are the factories themselves, with human help

The @OpenAIDevs team was nice enough to give me a preview of WebMCP in ChatGPT. It was fun to explore the design space of UIs that agents and humans can use together!

And now for something completely different...

Interesting to see SaaS companies starting to report MCP usage on earnings calls:
- Datadog: MCP tool calls up 4x q/q, 22x since Q4 2025
- Figma: MCP write usage up 75% q/q
- Atlassian: MCP calls up 400% q/q

whenever something is crazy hype and is followed up by an armada of PR, you gotta bring out the bullshit detectors
so i cloned the repo and did a little digging and found a lot of sound and fury. please enlighten me if any of these facts are untrue, would love to be educated
RLM claim either overblown or false
this doesn't even appear to be RLM (arxiv.org/abs/2512.24601)? RLM is "cool" as a concept because there's a premise of going infinitely deep to do arbitrary decomposition of a problem. in practice though it's not really hard, you just make subagents callable as functions and wrap that in a code execution tool. the reason RLMs have not been productionized and is just seen as a research ditty is that 1) going arbitrarily deep down the stack is a shitty thing to do in production without guardrails, 2) most problems do not need more than 2 layers of decomposition, and 3) agents are bad at banana phoning each other and will fail to preserve the subtleties of human requests, leading to a lot of inefficiencies and bad behavior.
to solve these problems, there needs to be a fair bit of innovation, either on model training end or on harness end, to mitigate these issues. so what were the innovations in prime agent?
they set RLM_MAX_DEPTH = 1? ... ok what? so theres no innovations, it's just calling subagents like every other harness in existence. if RLM MAX DEPTH is 1, it's not even RLM? it's just... a harness?
so now i try to look up to what depth the ARC AGI 3 hillclimbing was done at. not surprisingly this doesnt seem to be disclosed on the blogs / posts. if it's just 1 layer deep, that's just shady marketing.
a real innovation or contribution to harness engineering would be to detail the things that were improved to get a max depth of >3 to work without blowing up your computer, wasting a bajillion tokens, taking forever, or having agents go off the rails. i didnt find any
97% is just overfitting after hillclimbing on a public eval
ok folks. it's nice that opus5 does better than sol than terra, but at the end of the day, we're looking at a public eval in which problems and solutions are open access, so any agent harness can arbitrarily overfit to the task set however much it wants to. if you do a codex or claude loop with some semi shady prompting to just get 100%, im pretty sure it will too. now obviously this is almost certainly not what the prime intellect team instructed their agents to do (otherwise you'd see that terra get 100% after a couple iterations), let's just all remember that there is no train / test split, and that ARC explicitly says
- Public-set scores are vulnerable to task-specific overfitting.
- They are “emphatically not” valid evidence of progress toward AGI.
- Real generalization should be tested on the 55 semi-private or 55 fully private games.
It's difficult to assess the degree of overfitting in Prime Agent's self-improving harness (which, btw, is not terribly different from nous agent or really any self-improving system that just looks at old JSONL agent trajectories and suggests skills / memories / system prompt appendments / tools / extensions). the more overfitting, the less impressive the 97% performance is.
a counter-example that i found to be legitimately impressive was github.com/alexisfox7/PRO-LO… -- minimal / almost no overfitting, stupidly simple and general solution, and 95% on ARC AGI 3.
i think the fairest thing to say about this system, given it's independent daemon system for managing subagent lifecycles, is that Prime Agent contributes a fairly robust persistent asynchronous agent-process tree. It does not demonstrate a solution to scalable deep recursive agency
