GLM 5.3 Flash now available on AI Gateway
GLM 5.3 Flash joins Vercel AI Gateway with text and vision input, a 1M-token context window, function calling, structured output, and streaming.
Z.ai’s **GLM-5.3 Flash** is available as **zai/glm-5.3-flash**. It accepts text and vision input, has a **1M-token context window**, and supports function calls, structured output, and streaming.
Builders can connect supported coding agents through AI Gateway and evaluate the model for screenshot-to-code or other visual tasks; requests may include multiple images by URL or Base64 data URL.

Builders can connect supported coding agents through AI Gateway and evaluate the model for screenshot-to-code or other visual tasks; requests may include multiple images by URL or Base64 data URL. The material supplies no benchmarks, prices, output limits, latency, or reliability measurements, so availability and interface support do not establish coding performance.
GLM-5.3 Flash expands the million-token visual-agent pool with concrete interface support for multiple images, function calls, structured output, and streaming. Those capabilities make screenshot-to-code integration testable, but do not show that the model outperforms adjacent multimodal routes. Selection still requires matched workload testing because cost, latency, output capacity, reliability, and benchmarks are absent.
