QwQ Plus

qwenqwen/qwq-plus

Reasoning-focused Qwen — full thinking traces in every response.

qwq-plus is a reasoning-first model in the Qwen line. Unlike chat-tuned models, it always runs in thinking mode and returns its `reasoning_content` trace alongside the final answer — useful when you want to inspect or audit how the model arrived at a conclusion.

Use it on problems where reasoning quality is the deciding factor: math, multi-step planning, complex tool selection, and structured analytical tasks. TheRouter routes between bailian-cn and bailian-sg per request based on cost; `reasoning_content` passes through verbatim.

Always-on thinking
Returns `reasoning_content` on every response — no `enable_thinking` toggle required.
Reasoning specialist
Tuned for math, logic, planning, and multi-step tool selection over conversational chit-chat.
128K context
Enough context for full problem statements, prior reasoning traces, and tool results.
Dual-region routing
Selector picks bailian-cn or bailian-sg per request based on cost.
When to use
Math problems, multi-step planning, audit-friendly reasoning, complex tool selection, and analytical tasks where the thinking trace itself has value.
When not to use
Latency-critical chat, autocomplete, or any UX where the user does not benefit from the thinking trace — pick qwen-plus with thinking off, or qwen-turbo / qwen-flash.
Pricing: $1.00 input / $3.00 output per MTok. The `reasoning_content` tokens count toward output billing. TheRouter routes to the cheaper of bailian-cn / bailian-sg per request.
