    That's using TTC rather than pass@1 to get 65.8 on SWE-Bench Verified. You don't even read the diagram you post.

    I was given early access to Grok 3 earlier today, making me I think one of the first few who could run a quick vibe check. Thinking ✅ First, Grok 3 clearly has an around state of the art thinking model ("Think" button) and did great out of the box on my Settler's of Catan

    Great to see that @RosalindPicard 's keynote at #NeurIPS2024 tackled the important issue of discrimination in the AI community — by embodying it. Truly a masterclass in irony. @NeurIPSConf @MIT

    Mitigating racial bias from LLMs is a lot easier than removing it from humans! Can’t believe this happened at the best AI conference @NeurIPSConf We have ethical reviews for authors, but missed it for invited speakers? 😡

    Did you remember the "help me write an email" example Sundar presented in #GoogleIO weeks ago? We just released Rewrite PaLM 2, an instruction-tuned LLM that empowers the amazing "help me (re)write" features for Gmail and Workspace. Check our paper: arxiv.org/abs/2305.15685

    This thread is truly a live example of "抛砖引玉" lol. It's delightful to see a trivial prompt spark such concise and artful decodings from Andrej.
