TokenGo
Z.ai shipped GLM-5.3-Flash on August 26, 2026, as a distinct 320B-parameter mixture-of-experts model that activates only 18B parameters per token, runs natively in FP8, and supports a 1,048,576-token (1M) context window. Per the model card, it starts from a newly trained base model with a redesigned architecture and tr The flash variant beats GLM-5.2 across six coding/agentic benchmarks at roughly one-tenth the price, with API pricing set at $0.15 per million input tokens and $0.50 per million output tokens, and the vLLM inference recipe is already public. It approaches Claude Opus 4.8 on long-horizon agent tasks. Notably, the flagsh
