Feldman: Nvidia CUDA lost 70% of frontier AI model training market share
“I think two years ago every state of the art model was trained in a Cuda flow. And right now, Gemini is trained without Cuda. Anthropical is trained without Cuda. Open AI as strange as could. So in a one or two year period, they lost 70% share. Of training mod…”

Izmailov: AI industry excels at execution but lacks bandwidth for exploration
“Industry is really great at executing on ideas and it's maybe not as good at, like, exploring diverse ideas. Even at the scale of Anthropic OpenAI there is a lot of focus in the companies, and there isn't a lot of bandwidth to do exploration, and that has been…”

“And so quad code actually doesn't use this technique called rag. Instead, what it does is it just searches files the same way that a human would.”
Cherny: Code is the primary path for AI to reach AGI
