Summary

The article refutes the idea that AI development is slowing down, highlighting that Grok4.8, a 2.5T parameter model, has finished training and that major tech companies are still actively training AI models.

That ghost story about AI development slowing down—read it, have a laugh, and move on; don't fool even yourself. Grok4.8 with 2.5T parameters finished training this week. From what I've heard around this week, all the big Silicon Valley firms are still training away like mad, no change whatsoever. Wall Street can't see that? Impossible. It's true that AI self-iteration needs stronger Post-Training and Alignment, but it's been maliciously twisted into "AI development slowing down," and through non-experts' interpretations, it's snowballed. The more the market hypes up that AI slowdown ghost story, the better my opportunities get—in every sense of the word.
