📢Meet Qwen3.8-Max — our most capable model to date. Next week, the open weights of Qwen3.8-Max will be released, and Qwen3.8-27B is also going open-weights to meet you all!🎉 Qwen3.8-Max, a new bar for coding and cowork at 2.4T parameters: - Autonomous coding: 10+ days of s…
major price cuts today: *80% drop for GPT-5.6 Luna, now $0.20 per million input tokens and $1.20 per million output *20% drop for GPT-5.6 Terra, to $2/$12 *GPT-5.6 Sol gets Fast mode in the API, up to 2.5x the speed for 2x the price, same intelligence https://t.co/erC6u4VoDR
After deployment, we applied GPT-5.6 Sol to advance the frontier of efficiency by making itself more efficient to run. The results: - 20% lower serving costs from production GPU kernel improvements. - 15%+ better token-generation efficiency from improved speculative decoding.
Given some of the results I'm seeing recently, it's pretty clear Codex is a good harness. But it will seem primitive in 2-3 months and we're about to go through another major evolution in how we use AI at the frontier. The next generation of models need more than your laptop.
THIS HAS TO BE THE STORY OF 2026 Ken Griffin’s Citadel was pushing surprise-rate-hike fears just days before the AI trade collapsed and forced 4x-levered Leopold Aschenbrenner's Situational Awareness to unload its book near the lows. Citadel then reportedly bought most of thos…
An internal version of our next major model produced 10 new results on long-standing open problems in mathematics and theoretical computer science, using roughly $2,000 worth of tokens at GPT-5.6 Sol API rates. https://t.co/4cgowmPOpY
We quietly released the open-source Codex Security CLI, but Hacker News found it before we had a chance to share it here... You can now use it to scan repositories, track findings across runs, verify fixes, and add security checks to CI/CD. This is an early release, and we're…
Five months ago we gave the Claude agents a brand new $50,000 portfolio and one instruction: beat the S&P 500 So far mission accomplished • Up 19.04% since March 3 vs 12.24% for the S&P • $27 million now copying the trades • Every position and every trade public https:…
Here is the full letter Leopold sent to his LPs last night. Rumors of his demise are greatly exaggerated. https://t.co/5yIzR0DKIp
After doing ~60B tokens, this is my full AGENTS.md https://t.co/VVXIwtSAcO
GPT-5.6 Sol has been used to solve open problems in mathematics. So why was it struggling with ARC-AGI-3, a benchmark of 2D puzzle games? We investigated. The harness was not letting it remember what it had learned. We found that enabling two API settings tripled our scores w…

We support this petition, signed by our CEO, several co-founders, and senior staff. Our own research on recursive self-improvement, published last month, points to the need for tools to deliberately pace the frontier of AI development so society can prepare. We’re glad to see …
Here is my AI investing guide. Sitting here August 2026, my current best thoughts are as follows: 1. LPS (Land Power Shell) is still the most obvious and fastest path to cash on cash returns. Lots of value can be assembled and traded quickly at this layer. And as data centers …
We're open-sourcing Mixture-of-Kittens (MoK), our MoE training megakernel for NVL72s. It fuses all Mixture-of-Experts communication and computation into a single, fully deterministic kernel, and runs up to 2.37x faster than the strongest public baselines. https://t.co/yHu5E6RXp9
Introducing Applied Electrodynamics. What would the world look like if we could see beyond visible light, across the entire electromagnetic spectrum? The way waves interact with matter, at every wavelength, encodes far more than just shape and color. It reveals internal struct…
finally a planner that thinks in time, not lists.. your day curls around the clock face https://t.co/6XOpYCt2Ir
lol did nobody at Anthropic stop for a second and wonder why the numbers looked this absurd before posting the “victory”-tweet? https://t.co/DPdPc04YZT
I tried asking myself what I'd learned after 40, and it turned out to be a lot of the most important stuff I know. At least 90% of what I know about startups, because I was 40 when we started YC. Plus everything I know about parenting and most of what I know about writing.
