Our latest model advances bring stronger capabilities for building and migrating software in low-resource programming languages such as COBOL, Fortran, and Visual Basic.
These languages power software that banks, governments, and businesses depend on. Progress here means understanding decades of business logic and helping developers modernize those systems while preserving what works.
We’re building these capabilities around the challenges developers and enterprise customers bring us. If your team is working on these systems, tell us which languages and workflows we should tackle next.

we're now cooking with heat - congrats richard & team!

Usage share of OpenAI grew vs Anthropic yesterday despite Mythos 5 / Fable 5 launch
Multiple power users at SemiAnalysis tried Mythos / Fable
Got refusals for nonsensical reasons
Got pissed off at Anthropic
Gave Codex a legitimate try
Now they actually prefer it to 4.8 Opus – at San Francisco, CA
sign up for your install today!
I’ve had access to Codex2 and GPT 5.5 for about 2 weeks now
OpenAI just collison-installed all of NVIDIA lol
They set up a lab like a Genius Bar so everyone could get set up w Codex 2
With the CLIs we’ve been building, non-technical coworkers seemed to have the biggest unlock
Our stack:
• We rolled out cloud VMs for every employee. Simple rule, agents get their own computers just like employees. If something goes wrong we can freeze it and get a stack trace.
• Codex team has been super responsive. Codex 2 now supports any cloud vm, quickly picks up ssh config. Non-technical users just paste a prompt we gave them to edit ssh config
• Internally built CLIs + those vetted by security get automatically loaded in cloud VMs. Teams wake up to new capabilities daily now.
NVIDIA already moved fast now we’re rippin 🤙

an exciting result from the team! so much left to do
At @OpenAI, we believe that AI can accelerate science and drug discovery. An exciting example is our work with @RetroBiosciences, where a custom model designed improved variants of the Nobel-prize winning Yamanaka proteins. Today we published a closer look at the breakthrough. ⬇️

this tweet made me realize that choosing AI models kinda feels more like hiring people than evaluating a technology...
- hard to quantify strengths / weaknesses
- you learn a lot from a week working together
- references from trusted people are helpful
- trust builds slowly
vibe coding gets most of the airtime around ai’s impact in software engineering
but the real prize is simplifying gnarly slogs like migrations

the best is yet to come
chatgpt recently crossed 400M WAU, we feel very fortunate to serve 5% of the world every week
2M+ business users now use chatgpt at work, and reasoning model API use is up 5x since o3 mini launch
we'll bring GPT-4.5 and GPT-5 to chat and the API soon, with unlimited GPT-5 for free users (plus and users can run at even higher intelligence)
GPT-5 will unify our GPT and o-series models into a single powerful model -- we think even low-taste testers will love it
more agent capabilities coming this year as well, and a few other things

deep research has meaningfully changed the way i work and learn. excited for folks to try it in chatgpt later today

even though i've been using this for some time, it's still consistently delightful and magical - excited for more folks to try it
Advanced Voice is rolling out to all Plus and Team users in the ChatGPT app over the course of the week.
While you’ve been patiently waiting, we’ve added Custom Instructions, Memory, five new voices, and improved accents.
It can also say “Sorry I’m late” in over 50 languages.

hypothesis: o1 excels in business domains requiring deductive thinking, concrete or "correct" answers, and thoroughness over speed
Yesterday, OpenAI dropped a preview of a new model, o1.
Our initial observations are that the o1-preview model is more autonomous in generating steps to solve problems, more precise, and handles complex tasks with higher consistency. The more digestible formatting of outputs and its increased sense of ‘confidence’ relative to 4o help too. o1-preview will unlock new use cases & accelerate time to deployment for existing use cases in healthcare. Here are several healthcare examples. 1/6
