Common questions
Qwen3.8-Max
Answered from the verified figures on this page rather than general guidance.
How much does Qwen3.8-Max cost per million tokens?
Qwen3.8-Max is listed at $2 per million input tokens and $6 per million output tokens at standard rates. Output tokens usually dominate real bills, so weigh the output rate more heavily than the input rate.
What is Qwen3.8-Max's context window?
Qwen3.8-Max accepts about 1M tokens of context. That only matters if you routinely send very long documents, large codebases, or multi-turn histories that approach that limit.
What is Qwen3.8-Max best for?
Qwen3.8-Max is a frontier tier from Qwen. It suits agentic coding, multimodal knowledge work, long-context delivery. This row is the hosted Qwen3.8-Max API, not the downloadable checkpoint. The open-weight Qwen3.8-2.4T-A95B card is catalogued separately and does not include the API's vision, non-thinking, or built-in tool extras.
