About GLM 5.2
zai-org/GLM-5.2 is a large Mixture-of-Experts language model from Z AI built for long-horizon coding and agentic tasks. It introduces a 1M-token context window and multi-effort coding capabilities that improve sustained performance across long, multi-step workflows.
Its IndexShare architecture and improved MTP layer reduce per-token FLOPs while increasing speculative decoding lengths, boosting efficiency without sacrificing quality. GLM-5.2 supports function calling and is well suited for agentic engineering, code assistance, and tasks that require reasoning over very long contexts.
