Where Qwen3.8-Max fits
On a blended 3:1 basis Qwen3.8-Max costs $3.00 per 1M tokens, cheaper than 34% of the 80 priced models in this index. As Alibaba Qwen's flagship it is aimed at the hardest workloads — complex reasoning, agentic coding and multi-step tool use — where output quality dominates cost. Measured output speed of 39 tokens/sec is below the index median of 104 — typical of reasoning-heavy models, and worth checking against interactive latency budgets. Cached input is priced at $0.25 (88% below standard input), which rewards prompt structures with long stable prefixes — see our caching guide.
