I never felt good about Dario Amodei, but I still tried to give him the benefit of the doubt & even declared him as one of my AI heroes. It seems my original intuition was correct. But, due to my intense AI optimism, I didn't think he would end up being this damaging. I was wrong

There's a big misconception about how GLM 5.2 was trained. Yes, they distilled Claude and GPT 5.5 — but distillation is not how they matched Opus quality. Distillation only fixed the cold start problem in RL. RLing an agentic coding model isn't rocket science. In simplified

How good is GLM-5.2? GLM-5.2 (Max) ranks higher than Claude Opus 4.8 (Thinking) on Code Arena, where Frontend coding tasks are being voted on by the community. Below in thread are 10 examples of the same prompts given to both models and completed in a single shot.

With the new ARC-AGI results from GLM 5.2, together with the WeirdML results, we now have 8 private benchmark datapoints on the gaps closed by GLM 5.2, for an average of 8.1 months. This is consistent with the trend in my (pre GLM 5.2) analysis, but is some evidence against the […

Supposedly, “a new model from” from zAI is said to be at least as strong as Fable5 in cybersecurity-related aspects. I did some research and only came across a Wall Street Journal article, which, however, does not refer to a new model, but to GLM 5.2 as a relatively new model [im…

The #1 article on the Wall Street Journal claims that GLM-5.2 matches Mythos at finding security bugs. This is almost certainly completely incorrect. I am willing to put up $100 for $1 that GLM-5.2 will score below Mythos and GPT-5.5 at UK AISI's cyber range. WSJ has been... [ima…
