Information from the OpenRouter platform indicates that Z.ai (Zhipu AI) has introduced the GLM 5.2, a large-scale reasoning model. The model supports text input and output and features a massive 1 million token context window.

Pricing is set at $0.36/$0.75 per million tokens for input/output. GLM 5.2 supports high and xhigh reasoning efforts and is specifically optimized for coding and tool use across long-running tasks. It is designed to maintain engineering context throughout a full development workflow—from requirements to multi-platform deployment—making it highly suitable for long-horizon agentic workflows.
