GLM 5 is Z.ai's flagship open-source foundation model, engineered for complex systems design and long-horizon agent workflows. Built for expert developers, it delivers production-grade performance on large-scale programming tasks.
With advanced agentic planning, deep backend reasoning and iterative self-correction, GLM 5 moves beyond code generation to full-system construction and autonomous execution. Its roughly 200K-token context window suits large codebases and multi-step tasks. 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: $1.2/M in · $3.5/M out. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
