GLM 5.3 Flash
AffordableZ.ai's efficient multimodal model for fast coding and long-horizon agent tasks.
1.3M-token context with text, image, and video input. The hybrid sparse and linear attention architecture keeps long-context behavior accurate while cutting compute overhead, at a fraction of GLM 5.3's price.
▼
GLM 5.3 Flash is somewhat expensive at $0.15/M tokens input and $0.50/M tokens output. Cached input reads are priced at $0.03/M tokens, making repeated context cheaper. The model supports vision/image input, extended reasoning, a 1M context window.
