GLM-5.3 Flash is live on xKiro: 1M-token context, vision and agentic coding

GLM-5.3 Flash — Z.ai's natively multimodal 320B-A18B MoE model — is now available on xKiro through the same OpenAI-compatible API you already use. It brings a 1M-token context window, image input and flagship-class agentic coding at a fraction of the GLM-5.3 price. Call it as z-ai/glm-5.3-flash on /v1/chat/completions with no new setup.
