    Check out Muse Spark, our first milestone in the quest for personal superintelligence! Scaling this with the team has been a total blast. Give it a spin and let us know what you think! 🥑

    o3-mini is here! Together with @shengjia_zhao, @_kevinlu, @max_a_schwarzer, @ericmitchellai, @brian_zq, @sandersted and many others, we trained this efficient reasoning model, maximally compressing the intelligence from big brothers o1 / o3. The model is very good in hard

    We released o3-mini today! Everyone can use it for free. It reasons hard, reasons fast, searches the web, and most importantly, knows research. Ask the model hard questions and brainstorm with it!

    thank you to the external safety researchers who tested o3-mini. we have now finalized a version and are beginning the release process; planning to ship in ~a couple of weeks. also, we heard the feedback: will launch api and chatgpt at the same time! (it's very good.)

    Excited to present o3-mini today at @OpenAI 12 days with @sama, @markchen90 and @GregKamradt! Check out the live demo where I asked the model to write a script to automatically evaluate itself on GPQA dataset from an interactive code generation/execution UI created by itself.

    Replying to @OpenAI
    We also shared evals on Open AI o3-mini — a faster, distilled version of o3 which is optimized for coding, and the first version of o3 we expect to make available for use in early 2025.

    Check out the latest open models. Absolutely no competitor of the same scale. Towards intelligence too cheap to meter.

    we are going to take a little more time with our open-weights model, i.e. expect it later this summer but not june. our research team did something unexpected and quite amazing and we think it will be very very worth the wait, but needs a bit longer.

    Thrilled to release o1-mini, a model near and dear to my heart 💙. o1-mini is an efficient model in the o1 series that’s super performant in STEM reasoning, especially math and coding. I can’t wait to see what you all build with o1-mini!!
    The image features the text "o1-mini" in white, centered on a background with swirling gradients of yellow and light blue. The colors blend smoothly in a circular pattern, creating a soft, dynamic effect.

    change of plans: we are going to release o3 and o4-mini after all, probably in a couple of weeks, and then do GPT-5 in a few months. there are a bunch of reasons for this, but the most exciting one is that we are going to be able to make GPT-5 much better than we originally

    Very excited to finally share OpenAI's "deep research" model, which achieves twice the score of o3-mini on Humanity's Last Exam, and can even perform some tasks that would take PhD experts 10+ hours to do! A few thoughts on the implications: Deep research can be seen as a new
