Thinking levels: Always thinks · max · high · low
GLM 5.3 Prime has the full abilities of Z.ai's GLM-5.3 but is served with inference acceleration that roughly doubles output speed. It reads up to 1M tokens of text, writes up to 128K tokens in one reply, and always reasons before answering, with low, high and max effort levels. It targets coding and agent orchestration, where faster output shortens every step of a long run.
It accepts text input and returns text, and supports tool calling, structured JSON output and streaming. It always reasons before answering, and you choose how hard it thinks with the reasoning effort setting. GLM 5.3 Prime is commonly used for coding agents, long multi-turn agent orchestration, real-time chat and streaming code generation. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.
Pricing is usage-based: $2.8 per million input tokens and $8.8 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
GLM-5.3-Prime is the high-speed variant of Z.ai's GLM-5.3, inheriting its full capabilities while delivering 1.5–2× the output throughput through inference acceleration. It supports text input and output with a 1M-token...
