   Gavin Baker's approach to processing AI model releases like Gemini 3

   • Gavin emphasizes the importance of personally using the highest tier of AI models, as free tiers are like dealing with a 10-year-old and can't extrapolate to the full capabilities.
   • He follows key AI researchers and labs on X (Twitter), where much of the AI discourse happens, and uses AI tools to help keep up with the constant stream of information.
   • He notes that many investors make definitive conclusions about AI based on free tiers, which is a mistake.

   The state of frontier model progress and scaling laws

   • Gemini 3 confirmed that scaling laws for pre-training are intact, which is crucial because no one fully understands why they work, but they've held empirically.
   • Progress in AI stalled from mid-2024 to Gemini 3 due to the delay in Blackwell chips, but reasoning models bridged the gap with new scaling laws like reinforcement learning with verified rewards and test-time compute.
   • Google's TPU v6 and v7 are like F4 Phantoms compared to Blackwell's F-35, giving Google a temporary advantage in pre-training.

   The competitive dynamics between Google, Nvidia, and other chip players

   • Google has been the low-cost producer of tokens, which is a new phenomenon in tech where being low-cost matters for the first time.
   • Nvidia's Blackwell chips were delayed due to complexity, but once deployed, they will make Blackwell models amazing, with XAI likely to have the first model trained on them.
   • The GB300 chip is drop-in compatible with GB200 racks, making it easier to deploy and potentially shifting the low-cost producer status away from Google.

Ключевые понятия

• scaling laws— Central to understanding AI progress; Gemini 3 confirmed they hold.
• TPU vs GPU— Key competitive dynamic between Google and Nvidia.
• ASIC— Custom chips like TPU and Trainium are challenging Nvidia's dominance.

Знаковые цитаты

• The free tier is like you're dealing with a 10-year-old and you're making conclusions about the 10-year-old's capabilities as an adult.

  💡

  — Highlights the mistake of judging AI capabilities based on free versions, which are severely limited.

• Everything in AI is just downstream of those people.

  🔥

  — Emphasizes the importance of following top AI researchers for insights, rather than relying on general media.
