GLM 5.3 FlashX
StandardZ.ai's high-speed variant of GLM 5.3 Flash, generating up to 200 tokens per second.
Same hybrid sparse and linear attention architecture (320B total, 18B active) with a 1M-token context and text, image, and video input. Suited to efficient coding, visual understanding, and long-horizon agent tasks where generation speed is the bottleneck.
▼
GLM 5.3 FlashX is somewhat expensive at $0.37/M tokens input and $1.25/M tokens output. Cached input reads are priced at $0.09/M tokens, making repeated context cheaper. The model supports vision/image input, extended reasoning, a 1M context window.
