Qwen Max

qwenqwen/qwen-max

Previous-gen Qwen flagship — still strong on reasoning and tool use.

qwen-max is the previous-generation flagship in the Qwen series. Even after Qwen3 launched it remains a credible choice for reasoning-heavy chat, structured output, and function-calling workloads, with a 128K context window that comfortably handles long documents.

Use it when you want flagship-tier behaviour at a flat, predictable price and don't need Qwen3-level coding or the 256K context of qwen3-max. TheRouter routes between bailian-cn and bailian-sg per request based on cost.

Strong reasoning
Solid chain-of-thought, math, and multi-step tool-use performance from the previous-gen Qwen flagship.
128K context
Long-document analysis, large code reviews, and extended agent histories fit in a single call.
Function calling
Native tool/function calling with OpenAI-compatible schemas — no wrapper SDK needed.
Dual-region routing
Selector picks bailian-cn or bailian-sg per request based on cost — failover is automatic.
When to use
Reasoning, structured output, and tool-use workloads where you want a flagship-tier Qwen at a steady price and Qwen3-max's premium is not justified.
When not to use
If you need the absolute top of Qwen on coding or 256K context, upgrade to qwen3-max. For high-volume cheap chat, drop to qwen-plus / qwen-turbo.
Pricing: $2.00 input / $8.00 output per MTok. TheRouter picks the cheaper of bailian-cn / bailian-sg per request.
