I agree putting as much as possible on chain would be a great thing. A GPU subnet, 64bit wasm and some other protocol enhancements will enable more and more things to run fully on chain. We should already try, because the IC is more powerful than most people think, and LLMs already run remarkably well on the current architecture.

No timelines for the upgrades, but much discussion on going, also within the DeAI Working group. Node providers are very involved in driving next Gen ICP nodes that are optimized for AI.
