Z.ai's GLM 5.3 Flash is now available on Vercel's AI Gateway as zai/glm-5.3-flash. It's a multimodal coding model with a 1M-token context window, accepting both text and image inputs, and supporting function calling, structured output, and streaming.
Images can be sent alongside text in a single message, using URLs, Base64 data URLs, or binary data. To use the model with a coding agent, run vercel ai-gateway coding-agents setup and select zai/glm-5.3-flash. It can also be tried in the model playground.
