Brief

Z.ai announced GLM-5.2, an MIT-open checkpoint intended for unrestricted technical access. The model emphasizes long-horizon reasoning with a 1M-token context window, improved coding and agentic capabilities, and two operating modes (max and high). Weights are available on Hugging Face and the API keeps GLM-5.1 pricing, with blog, docs, and subscription links provided.

Why it matters

Z.ai released GLM-5.2 on 2026-06-16 with MIT-licensed open weights and no regional restrictions (weights hosted on Hugging Face).

Key details

  • GLM-5.2 adds a 1,000,000-token context window, claims significant gains on coding and agentic tasks, and offers two reasoning modes: GLM-5.2 (max) for top performance and GLM-5.2 (high) for token efficiency; API pricing remains the same as GLM-5.1.
