GLM‑5.2 eclipses open‑weight rivals with 1 M token context and lower costs
Z.ai dropped GLM-5.2, a 753B‑parameter text‑only model with a 1 M token context window, under an MIT license. It now tops the Artificial Analysis Intelligence Index for open‑weights LLMs, beating DeepSeek and MiniMax while costing far less per token than GPT‑5.5 or Claude Opus. The model’s token hunger and mixed creative results hint at both promise and trade‑offs.
