deepseek's r1 is an impressive model, particularly around what they're able to deliver for the price. we will obviously deliver much better models and also it's legit invigorating to have a new competitor! we will pull up some releases.

o3 and o4-mini are super good at coding, so we are releasing a new product, Codex CLI, to make them easier to use. this is a coding agent that runs on your computer. it is fully open source and available today; we expect it to rapidly improve.

a few times a year i wake up early and can't fall back asleep because we are launching a new feature ive been so excited about for so long. today is one of those days!

Opens with an observation

Sam Altman@sama

we have greatly improved memory in chatgpt--it can now reference all your past conversations! this is a surprisingly great feature imo, and it points at something we are excited about: ai systems that get to know you over your life, and become extremely useful and personalized.

astra is a powerful model and we are working to make it generally available. we do not think it is a good strategy to keep powerful models to a chosen few. given its cyber capabilities, we need a little big longer to do do this safely. but hopefully not too long!

the last couple of GPT-4o updates have made the personality too sycophant-y and annoying (even though there are some very good parts of it), and we are working on fixes asap, some today and some this week. at some point will share our learnings from this, it's been interesting.

o3-mini is out! smart, fast model. available in ChatGPT and API. it can search the web, and it shows its thinking. available to free-tier users! click the "reason" button. with ChatGPT plus, you can select "o3-mini-high", which thinks harder and gives better answers.

we just launched two things: o1, the smartest model in the world. smarter, faster, and more features (eg multimodality) than o1-preview. live in chatgpt now, coming to api soon. chatgpt pro. $200/month. unlimited usage and even-smarter mode for using o1. more benefits to come!

I am very excited about AI, but to go off-script for a minute: I built an app with Codex last week. It was very fun. Then I started asking it for ideas for new features and at least a couple of them were better than I was thinking of. I felt a little useless and it was sad.

this is a critically important moment for cyber defense with AI; there is not much time to act. we are happy if you want to work with us or any of our competitors or partners, but please take this moment seriously. only an urgent and intense collective response will work.

it is (relatively) easy to copy something that you know works. it is extremely hard to do something new, risky, and difficult when you don't know if it will work. individual researchers rightly get a lot of glory for that when they do it! it's the coolest thing in the world.

The companies that succeed in the future are going to make very heavy use of AI. People will manage teams of agents to do very complex things. Today we are launching Frontier, a new platform to enable these companies.

GPT-5.4 is launching, available now in the API and Codex and rolling out over the course of the day in ChatGPT. It's much better at knowledge work and web search, and it has native computer use capabilities. You can steer it mid-response, and it supports 1m tokens of context.

o3-mini-high is really good and it's cool to hear some people say it's their favorite model ever but it reminds me of when we used to have something internally called "the little big run" a top 2025 goal is to fix our naming problem

GPT-4.1 (and -mini and -nano) are now available in the API! these models are great at coding, instruction following, and long context (1 million tokens). benchmarks are strong, but we focused on real-world utility, and developers seem very happy. GPT-4.1 family is API-only.

wow so far DMs in a shockingly even dead heat between "you made a software engineer and didn't include unlimited use in the $20 plan? fuck you!" and "you made a software engineer and you're not charging $20k a month for it? what the fuck?"

we are launching sora today, and we made a new product to go with it. if you have an openai plus or pro account, you can generate videos. anyone can view them. it will take some time to roll out, but by the end of the day it should be available at t.co

but mostly we are excited to continue to execute on our research roadmap and believe more compute is more important now than ever before to succeed at our mission. the world is going to want to use a LOT of ai, and really be quite amazed by the next gen models coming.

openai usage has gone nuts over the past month. but a surprisingly cool thing is you can ask the internet "hey can we please get hundreds of thousands of more GPUs quickly" and...the internet will deliver. 🩵

first, sorry for the messy rollout. second, when we screw up, we try to make it right. third, we should be able to begin broad rollout to API customers and chatgpt subscribers in the near future. as usual we will start with pro subscribers.

it is amazing and exciting how much software one person is going to be able to create with tools like this. "you can just do things" is one of my favorite memes; i didn't think it would apply to AI itself, and its users, in such an important way so soon.

people are really starting to use voice to interact with AI, especially when they have a lot of context to dump. GPT-Realtime-2 comes to the API today; it is a pretty big step forward. (we are working on improvements to voice in chat.)

so excited that @fidjissimo is joining openai in a new role: ceo of applications, reporting to me. i'll remain ceo of openai, but in this new configuration i'll be able to increase my focus on research, compute, and safety. these are critical as we approach superintelligence.

it's very hard to get the math and ML right on a run as big as GPT-4.5, and requires difficult work at the intersection of ML and systems. @ColinWei11 , Yujia Jin, and @MikhailPavlov5 did excellent work to make this happen!

a general-purpose model solved a major open problem in mathematics. we'll be saying this a lot over the coming years, but this is a kinda big milestone. i'm very excited for AI to greatly extend our understanding of the world, but still, i have complicated feelings today.

customers are increasingly asking us for certainty on capacity. as models get better, we expect that the world will be capacity-constrained for some time. we are offering discounted tokens for 1-3 year commits. (it also helps us plan, so hopefully a big win-win.)

we have been thinking recently about the need for something like "AI privilege"; this really accelerates the need to have the conversation. imo talking to an AI should be like talking to a lawyer or a doctor. i hope society will figure this out soon.

we are introducing the Model Spec, which specifies how our models should behave. we will listen, debate, and adapt this over time, but i think it will be very useful to be clear when something is a bug vs. a decision. t.co

I love building with this model; it feels like more of a step forward than the benchmarks suggest. Also you can choose "pragmatic" or "friendly" for its personality; people have strong preferences one way or the other!

a few things are different about the api version than the chatgpt version: you can control moderation sensitivity with the 'moderation' parameter you can also control things like quality vs generation speed, background, output format, etc.

Last week, a security researcher using our previous model found and disclosed a vulnerability in React that could lead to source code exposure. I believe these models will be a net win for cybersecurity, but we are in the 'real impact phase' as they improve.
