After almost a decade, I have made the decision to leave OpenAI.  The company’s trajectory has been nothing short of miraculous, and I’m confident that OpenAI will build AGI that is both safe and beneficial under the leadership of Sam Altman, Greg Brockman, Mira Murati and now, under the

We built an AI creative team that turns a sentence into a full video. The waitlist is live. Sign up now👇

I had access to GPT-5. I think it is a very big deal as it is very smart & just does stuff for you Full write up in comments, but this is “make a procedural brutalist building creator where i can drag and edit buildings in cool ways" & "make it better" a bunch. I touched no code

GPT-5 is here - and it’s #1 across the board. 🥇#1 in Text, WebDev, and Vision Arena 🥇#1 in Hard Prompts, Coding, Math, Creativity, Long Queries, and more Tested under the codename “summit”, GPT-5 now holds the highest Arena score to date. Huge congrats to OpenAI on this

Awwww, working daily with you guys is the highlight of my career, and I have really high hopes that we have barely gotten started! 💜

we've 15x'd our compute since 2024 leading up to GPT-5 last 60 days: built out 60+ clusters, a backbone moving more traffic than entire continents, and 200k+ GPUs to launch GPT-5 to 700m people -- all while designing the next 4.5GW toward superintelligence

We're introducing GPT-5. The evals are SOTA, but the real story is usefulness. It helps with what people care about-- shipping code, creative writing, and navigating health info-- with more steadiness and less friction. We also cut hallucinations. It's better calibrated, says "I

Michelle Pokrass is unbelievably goated at intersecting research and engineering and she’s grown a whole team around it. Honored to ship under her leadership!!

GPT-5 captures our exciting research from the last two years. It builds on 4o (multimodal), o1 (reasoning), o3 (tool use, better reasoning, synthetic data), and has major new research of its own. Together these lead to strong performance on real-world use cases!

GPT-5 is here. It’s first model that I don’t ever think of switching. Available for free in Cursor this week, and it’s smarter, faster, cheaper than previous SOTA coding models. …and we have one more thing ⬢

gpt-5 is the best coding model in the world and is now the default in Cursor. youtube.com/watch?v=PQUcIb…

model switching in gpt-5 very cool!

when you get access to gpt-5, try a message like "use beatbot to make a sick beat to celebrate gpt-5". it's a nice preview of what we think this will be like as AI starts to generate its own UX and interfaces get more dynamic. it's cool that you can interact with the

GPT-5 has 4 new chat personalities: Cynic, Robot, Listener, Nerd. Find them in Customize ChatGPT in settings. Research preview. Text-only. Opt-in. Change anytime. Written by Robot in GPT-5.

thank you to our partners at microsoft, nvidia, oracle, google, and coreweave for making this possible! lots and lots of GPUs working overtime.

GPT-5 is the smartest model we've ever done, but the main thing we pushed for is real-world utility and mass accessibility/affordability. we can release much, much smarter models, and we will, but this is something a billion+ people will benefit from. (most of the world has

1 / Today we launched gpt-5, finishing a huge week for OpenAI. We’ve raised the bar for safety in both open and closed models. With gpt-oss and gpt-5, we introduced meaningful capability advancements with rigorous, industry-leading safeguards and safety testing.

GPT-5 now rolled out to 20% of paid users and doing >2B TPM on the API! so far so good... excellent work by the eng and infra teams!

GPT-5 rollout updates: *We are going to double GPT-5 rate limits for ChatGPT Plus users as we finish rollout. *We will let Plus users choose to continue to use 4o. We will watch usage as we think about how long to offer legacy models for. *GPT-5 will seem smarter starting

Wanted to provide more updates on the GPT-5 rollout and changes we are making heading into the weekend. 1. We for sure underestimated how much some of the things that people like in GPT-4o matter to them, even if GPT-5 performs better in most ways. 2. Users have very different
