An exciting moment for AI in complex algorithmic reasoning & coding. Our new Gemini Advanced model achieved Gold at the ICPC, a programming contest close to my heart! Also the beginning of an great journey in this space. So proud of the amazing team: https://t.co/Gy0Ix6oemx 1/4

We focused on a system that has potential to bring to all Gemini users. This is just the beginning. Tagging part of our incredible team: @zuza777 @stochasticlalit @JiemingMao @zichengxu42 (@magical on linkedIn) @HengTze 5/4 :)

❓Can I collect some feedbacks: Is fully open-source research necessary? Earlier, I released a family of 1-8B models (open data, code, weights): beating Llama3-8B with <10% pretrain time, beating most (all?) open-data models of this scale. 🔓No shortcuts: 10+ legal debates for
Phase 1 of Physics of Language Models code release ✅our Part 3.1 + 4.1 = all you need to pretrain strong 8B base model in 42k GPU-hours ✅Canon layers = strong, scalable gains ✅Real open-source (data/train/weights) ✅Apache 2.0 license (commercial ok!) 🔗 https://t.co/Nk3tOY2ICp

Now uploaded a 50-min video for Part 2.2, covering many technical details: https://t.co/2U1u1x37pm
(1/7) Physics of LM, Part 2.2 with 8 results on "LLM how to learn from mistakes" now on arxiv: https://t.co/3iFS1Z4IfU. We explore the possibility to enable models to correct errors immediately after they are made (no multi-round prompting). Check out the slides in this thread.

(1/2) Many asked for Part 2.2 and I'm sorry for the delay. Our author Zicheng Xu has been unexpectedly laid off. He has my strongest endorsement (see next post). If interested in this project or hiring him, contact him at zichengBxuB42@gmail.com (remove the capital 'B')
Incredibly honored and humbled by the overwhelming response to my tutorial, and thank you everyone who attended in person. Truly heartwarming to hear how much you enjoyed it. Many have been asking for a recording, and I prepared one with my own subtitles https://t.co/RjTm9ZHpId
