Model ID: zai-org-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.

Metric	Value
Parameter Count	743 billion
Mixture of Experts	Yes
Context Length	1,040,000 tokens
Multilingual	Yes
Quantized*	Unknown

*Quantization is specific to the inference provider and the model may be offered with different quantization levels by other providers.
