GLM 5.2 is a large-scale reasoning model from Z.ai. It takes text input and output, offers a context window of up to 1M tokens, and suits long-horizon agent workflows, project-level software engineering and complex multi-step automation.
Reasoning-effort levels "high" and "xhigh" are supported, with "xhigh" mapping to max reasoning. It is particularly strong at coding and tool use across long-running tasks, able to maintain engineering context through a full development workflow. From requirements to multi-platform deployment. In a single task. Hormouz exposes an OpenAI-compatible API. Point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs unchanged.
Pricing is usage-based: $3/M in · $10.25/M out. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
