Qwen: Qwen3.8 Max Prime

alibaba/qwen3.8-max-prime

Qwen3.8 Max Prime is the Fast mode (Prime) serving option for Alibaba's Qwen3.8 Max: the same model with the same vision input and reasoning, delivered at higher output speed. Alibaba states Fast mode raises tokens per second to about 1.5 to 2 times the standard API, aimed at latency-sensitive uses such as AI coding assistants, multi-step agent reasoning and real-time conversation. Pick it over standard Qwen3.8 Max when response speed matters; it adds no new capabilities.
