    Very proud of us @xai after seeing the GPT5 release. With a much smaller team, we are ahead in many. Grok4 world’s first unified model, and crushing GPT5 in benchmarks like ARC-AGI. @OpenAI is a very respectful competitor and still the leader in many, but we’re fast and

    Kudos to our crew 👏 "we've got a truly marvelous group of people, which this margin is too narrow to tag them all" fun side note: happy to witness two launches in a week😆 photoed in @SpaceX launch site, Starbase.

    Strongly recommend Grok 4 planning + Grok Code Fast execution. We will also ship out new coding products based on this concept soon.

    Three components of Reasoning for AI: 1. Foundation (Pre-training) 2. Self-improvement (RL) 3. Test-time compute (planning). @xai will soon have the best foundation in the world - Grok3. Join us to advance reasoning to the next-level! 🔥🔥

    Retire BrowseComp and use FinSearchComp! - Align with real financial experts' everyday work, where score means value! - Grok 4 is unbelievable 🔥even approaching human experts! GPT5 is also super cool, slightly behind Grok 4. - Search engine/capability is the new infra to AGI,

    Euclidean geometry problems have been my favorite math puzzles since middle school. The most intriguing part of it is the creation of auxiliary lines, which opens a space for imagination and the freedom to explore various diagrams. Once a proof is found, these auxiliary lines

    Boris, check out our mini model numbers, it surpassed o3mini high in all AIME 2024, GPQA, and LCB for pass@1. Generally I also don’t think our current benchmarks capture enough of the model intelligence. Our big Grok3 is worse on pass@1, but in our testing we can feel a smarter

    Updates to ChatGPT: You can now choose between “Auto”, “Fast”, and “Thinking” for GPT-5. Most users will want Auto, but the additional control will be useful for some people. Rate limits are now 3,000 messages/week with GPT-5 Thinking, and then extra capacity on GPT-5 Thinking

    Replying to @bindureddy
    It seems we're doing very well on code gen - #1 on your benchmark. But much worse on code completion. Since the chat interface is not suitable for such tasks, we did not target at this for the chat model. But we will release the API model that handles that well. Stay tuned!
