Description
GLM-5.3-Flash is the first natively multimodal model in Z.AI's GLM-5 series: a 320B-total / 18B-active MoE with hybrid sparse and linear attention (plus mHC), a 1M-token context window, and strong coding and long-horizon agent performance. MIT open weights are on Hugging Face. Launched 2026-08-26 after stealth testing as ox-alpha on OpenRouter and OpenCode. List pricing is $0.15/$0.50 per million input/output tokens (a temporary 50% promo ends 2026-09-09 16:00 UTC).
