About GLM-5.2
Z.ai's flagship open-weights foundation model released June 13, 2026. A 744-billion-parameter Mixture-of-Experts model with 40 billion active parameters per token, powered by IndexShare technology. Features a stable 1M-token context window optimised for long-horizon coding and agentic workflows, multiple thinking-effort levels (High and Max), and strong benchmark performance (81.0 on Terminal-Bench 2.1, 62.1 on SWE-bench Pro). Supports thinking mode, streaming, function calling, context caching, structured output, and MCP integration. Released under MIT license with no regional restrictions. Priced at $1.40 per million input tokens and $4.40 per million output tokens.
