GLM 5.3 FlashX is the fast edition of Z.ai's GLM-5.3-Flash, generating up to about 200 tokens per second. It uses the same hybrid sparse and linear attention design, with 320B parameters of which 18B are active per token, takes images as well as text, and reasons on every request. It suits efficient coding, visual understanding and long agent tasks over a 1M-token context.

It accepts text, image and video 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 FlashX is commonly used for fast coding agents, image understanding, real-time assistants and long agent runs. 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: $0.37 per million input tokens and $1.25 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.
