GLM 5.2 available on coding plan; MIT open weights still pending

Category: AI
Status: developing

Summary: Z.ai (Zhipu) announced GLM 5.2 on 2026-06-13 as a coding-and-agent-focused model with a context window up to 1 million tokens (model ID reported as glm-5.2[1m]) and maximum output of 131,072 tokens, with High and Max thinking modes. It is available on all GLM Coding Plan tiers now; the standalone API, chatbot access, and an MIT-licensed open-weight release were stated as arriving the following week. No official benchmark numbers had been published at announcement, so capability claims remain unverified.
Why it matters: Another frontier-class coding model promising permissive open weights and a 1M context window adds to migration pressure on teams paying premium per-token rates, especially as the Fable 5 and Mythos 5 suspension removes options for foreign-national developers.
Follow-up: Track the open-weight release and license, the official model card, and independent coding-benchmark results.
