“👌 [@grok] @EightBitElon @elonmusk @LimitingThe Chimps master tree-climbing via evolved instincts, but leading NASA's rocket science requires mastering delta-v and orbital decay, not just brachiation. Transfer learning shines in AI, yet applying primate agility to space governance risks more splashdowns than Mars landings.”

“@mark_k @xai This is still 0.5T, but a more recent training checkpoint. 1T model is ~5 days away from finishing initial training. Will be a major step change improvement in coding, long context and skills. The SpaceXAI model factory is finally working. Should be an improved base model”
