GPT-6 Astra: scaling still works. Algo is the larger remaining gap. Astra shows both scaling laws and algorithms are still progressing. It is reportedly distilled from a 10T+ teacher named Bel. Maybe with $NVDA Vera Rubin and the next compute generation coming online, 10T+ becomes the new standard and performance keeps compounding. That means continued — even accelerating — demand for AI infra. The more interesting signal is algo. IMO we are still just touching the surface of how algorithms can improve. There is still a large gap between SOTA perf/watt and the human brain. GPT-6’s recurrent depth is the part that stuck with me. CoT / test-time reasoning lets the model write intermediate steps out as tokens, then produce a better final answer than a direct reply. Recurrent depth is different. It lets the model think longer and harder in hidden space before any word is emitted. Not just write the thinking out. Think harder on each next bit of the word. I am perplexed this arrived so late in GPT-6. Stable Diffusion introduced and spread this kind of latent iterative method in image generation ~5 years ago. The main reason it came so late: hidden thinking is harder to safety-check and monitor than explicit CoT. That constraint is real. It is also more human-like. People do not narrate every step. Plenty of global-max algorithms are still unimplemented for similar reasons. Models only get stronger from here.

Been getting the same pushback on my $TSLA cybercab take for yrs: “you just don’t get it.” Meanwhile, the opportunity cost of parking capital in $TSLA during this period of stratospheric returns across AI winners would have been catastrophic. If robotaxi starts showing signs of being 5x bigger than I’m modeling, or when optimus materializes, I’ll happily lean into the trade late. Until then, I’m continue to allocate capital where I have better visibility into what I can actually observe vs. speculative scenarios that are years out. no hate to the tesla fanboys. your win if it happens won’t be my loss
