Z.ai has released GLM-5.2 as open weights under an MIT license, a 753B-parameter text-only mixture-of-experts model with a 1 million token context window. It leads open-weight models on Artificial Analysis’s Intelligence Index and ranks second on the Code Arena WebDev leaderboard, though benchmarks suggest it uses more output tokens per task than peers.
Chinese AI lab Z.ai released GLM-5.2, a 753 billion-parameter open-weight language model under an MIT license, positioning it as the most powerful text-only open model available. Benchmarks show it leads in performance but consumes more tokens than competitors, while early tests highlight strong coding and creative output, though some results lag behind its predecessor. The model is now accessible via multiple providers at competitive pricing.
