India is now our 2nd largest market after the US
weekly ChatGPT users have grown 4x in the last year, and India is now top 10 for API devs
later this year we’ll open an office in New Delhi, our first in India, to work more closely with Indian users, businesses, and partners!

mira is an amazing leader and equally great friend. i couldn't have asked for a better partner these last 6+ years, and am so grateful for her contributions to openai.
chief among those is the incredible technical team she's built, whose leadership will keep pushing the frontier. i'm excited to continue running at our mission with this world-class group.

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
New this AM: OpenAI tops 400 million users despite DeepSeek’s emergence
The company saw 400M weekly active users, up 33% in less than three months, according to OpenAI’s chief operating officer @bradlightcap

so much of work is what I like to call the “work around work” - switching between systems, chasing context, and stitching tools together to get things done
company knowledge in chatgpt now does this for you
it can reason across tools like slack, sharepoint, google drive, github, and more to get answers, do analysis, and take action using a version of gpt-5 that’s optimized for working with tools & providing citations
company knowledge has changed how i use chatgpt at work more than anything we have built so far - let us know what you think!

Announcing @OpenAI Pioneers, a new program for ambitious companies building with our API.
Selected teams will partner closely with us on domain-specific evals and custom fine-tuned models to advance AI product intelligence in their verticals.

we continue to see growth in every segment, from small startups and SMBs to fortune 500. we are working to make it easier for companies of any size to get to implementation and success quickly.
a shift we've seen lately is away from pilots and PoCs and toward wall-to-wall deployments. since introducing flexible credit-based pricing, customers are launching with 5x larger deployments.

We’re planning to release a very capable open language model in the coming months, our first since GPT-2.
Why are we doing this, and why now? More importantly – how can you help shape it? 🧵
TL;DR: we are excited to release a powerful new open-weight language model with reasoning in the coming months, and we want to talk to devs about how to make it maximally useful: openai.com/open-model-feedba…
we are excited to make this a very, very good model!
__
we are planning to release our first open-weigh language model since GPT-2.
we’ve been thinking about this for a long time but other priorities took precedence. now it feels important to do.
before release, we will evaluate this model according out our preparedness framework, like we would for any other model. and we will do extra work given that we know this model will be modified post-release.
we still have some decisions to make, so we are hosting developer events to gather feedback and later play with early prototypes. we’ll start in SF in a couple of weeks followed by sessions in europe and APAC. if you are interested in joining, please sign up at the link above.
we’re excited to see what developers build and how large companies and governments use it where they prefer to run a model themselves.

the commitment you’ve seen us show for our company is the same commitment we feel to our developers and users
So. About @OpenAI. I've been bombarded by sales calls from rival LLM companies seeking some opportunistic business wins. That's fair game and business is a contact sport so I get it. And we were already evaluating backup providers as a hedge before the drama. But the reason we're sticking with OpenAI beyond just the fact that their models are excellent is because they made a commitment to @BeMyEyes before that was a sexy thing to do. They prioritized accessibility when no one was looking. And they got in the trench with us to build a great product we call Be My AI™ even though it's close to meaningless for them from a revenue perspective. Thank you @sama, @bradlightcap, @JessicaShieh, and the many others that helped us along the way. I'm not going to opine on the Board drama except for one thing: We are 100% behind OpenAI because they and their people are phenomenal - both technically and personally.

built to run anywhere: locally, on-device, or through third-party inference providers. flexibility matters, especially in environments where cloud isn’t always an option. we’re excited to expand the action space for startups, enterprises, and governments.
thank you to early partners like AI Sweden, @orange, and @Snowflake, who have been testing these models in critical applications, from hosting on-prem for data security to fine-tuning them on specialized datasets.
open models are one way we make AI widely beneficial. we think giving more access (not less) is important.

there are many studies flying around and sure to be many more, but this one most reflects what we see on the ground at openai
ai is beyond the experimentation phase in enterprise - 95% of respondents here have used or intend to use chatgpt for work
over time, process will dominate productivity as ai shifts from accelerating one-off task steps like writing and analysis to entire processes within critical functions like eng, design, legal, sales, etc.
"improve this email to customer" will become "solve this customer's problem" will become "pls optimize CSAT"
we are just exiting the first phase, and starting to see glimpses of the second
👀New data on the corporate ROI from generative AI from a large-scale tracking survey by my colleagues at Wharton.
They found that 75% already have a positive return on investment from AI, less than 5% negative return. Also 46% of businesses leaders now use AI daily themselves.

learning is the most common chatgpt use case by far. we have heard a lot from students, parents, teachers, and industry about how to make it better.
study mode is an experiment to push learning even further:
- lessons are personalized to you based on questions that assess skill level and memory from previous chats
- it combines socratic questioning, hints, and self-reflection to make learning interactive
- it's fully multimodal and can use image generation to enhance learning

also odd that the new york times seems to be the only major news outlet silent about monday's landmark ruling protecting training as “exceedingly transformative” fair use 🤔
AI privacy is critically important as users rely on AI more and more.
the new york times claims to care about tech companies protecting user’s privacy and their reporters are committed to protecting their sources.
but they continue to ask a court to make us retain chatgpt users' conversations when a user doesn't want us to. this is not just unconscionable, but also overreaching and unnecessary to the case. we’ll continue to fight vigorously in court today.
i believe there should be some version of "AI privilege" to protect conversations with AI.

4.1 takes big steps forward in coding, instruction following, and context length up to 1M
it's 26% less expensive than 4o, and prompt caching discounts are now 75%; 4.1 mini rivals 4o on many intelligence benchmarks at 1/6th the cost
@windsurf_ai users will get unlimited 4.1 access for free for a week (!), with discounted access thereafter
@michpokrass and team did amazing work on this, we're excited to see what you build with it!
Thanks @openai for having me on the GPT-4.1 announcement livestream this morning!

As models improve, there is more and more demand to run them everywhere. Through conversations with startups and developers, it became clear how important it was to be able to support a spectrum of needs, such as custom fine-tuning for specialized tasks, more tunable latency, running on-prem, or deployments requiring full data control.
While we will continue to offer frontier models via our API and in ChatGPT, there are many scenarios where APIs alone won’t fully enable developers to build in the place, or in the way, in which they’d like.

with pro mode, you really can just ask chat to "solve for X" when it comes to analytical tasks.
