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.
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…
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…
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 …
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.

Some more detail on the ROIC Intelligence App I built yesterday and mentioned on today's earnings call. I took the PDF that Brian Nowak at Morgan Stanley put together for Hyperscale ROIC this week and used Copilot code (coming in our new superapp) with a single prompt + skill (…

Today, we are releasing Inkling-Small. Inkling-Small achieves comparable performance to Inkling at a quarter of its size. It features 276B total parameters, 12B active. We are making the full weights available. https://t.co/BtYNcpkDRA Fine-tune it on Tinker today, or chat wit…
Launching Copper, a Mac app for capturing things you want to keep and prompts you want to try next while working with AI. The more I use AI, the more I find myself collecting little things I don't want to lose. You're in ChatGPT and think, "I'll need this later," but you don't…

New blog post on what would be true about the world if trendline continues and leading lab hits $1T in revenue by the end of next year. In other words, why compute might get 10x+ more expensive in coming years https://t.co/7PvniDC2jN https://t.co/qJ1yhSkdyd
People keep on telling me that my message about AI is undercutting my own books. Those people do not understand how agents work and who actually controls them. You can't tell an agent to be clean. You have to measure the cleanliness that they produce and have them correct fai…
What's gone wrong with AI & labor — a thought experiment A thought experiment that I think helps explain much of what’s gone wrong with AI and labor: Imagine an alternate universe in which — for whatever reason — no one ever published source code online. The open source moveme…
"Lab compute 3x-es year over year. For a lab to 10x revenue while continuing to only 3x compute, some combination of the following 3 things has to happen: 1. Lab margins have to increase, 2. The price of compute has to increase, 3. Labs have to spend a greater fraction of …
