GLM-5.3-Flash

Native multimodal coding at flash prices, with a 1M window.

GLM-5.3-Flash is the first natively multimodal model in the GLM-5 line: 320B parameters with 18B active, a hybrid sparse/linear attention stack that cuts attention compute 3x and KV cache 4.4x against GLM-5.3, and a 1M-token window. It reads interfaces and rendered output inside the coding loop rather than through a separate vision pass.
