Zhipu launches GLM-5.2 with 1M-token context window, MIT open-source next week

GLM 5.2 Is Out

Zhipu's GLM-5.2 targets coding and long-horizon agent tasks with a 1M-token context window, available now to GLM Coding Plan subscribers. API access and MIT-licensed open weights are promised next week. The post doesn't disclose benchmark scores or parameter count. I'd hold off until weights actually land and third-party evals appear.

Why it matters: Zhipu drops GLM-5.2 with a 1M-token window, targeting code and agent use cases, with API and MIT-licensed weights promised next week. No benchmarks or param count in the post, so the score stays conservative until third-party evals land.
