Qwen3 Coder Plus

qwenqwen/qwen3-coder-plus

Repo-aware Qwen3 coder — tools, function calling, 256K context.

qwen3-coder-plus is the coding-specialised flagship of the Qwen3 generation. It is tuned for repo-aware tasks — multi-file refactors, function calling, agentic loops with shell / fs tools, and producing structured patch-style output — with a 256K context window that holds a small repo in a single call.

Bailian publishes tiered pricing for this model based on prompt length; the rate exposed to customers here is the standard short-prompt tier. TheRouter routes between bailian-cn and bailian-sg per request based on cost.

Repo-aware coding
Trained specifically for multi-file editing, refactors, and codebase understanding rather than single-snippet generation.
Function calling
Strong tool / function calling — fits naturally into agent loops with shell, fs, and HTTP tools.
256K context
Hold a small repo plus prior diffs in a single request — no manual chunking.
Dual-region routing
Selector picks bailian-cn or bailian-sg per request based on cost.
When to use
Coding agents, multi-file refactors, codebase Q&A, patch generation, and any pipeline where Qwen3-class coding behaviour and function calling matter.
When not to use
Non-coding tasks, broad chit-chat, or workloads where general reasoning matters more than code understanding — use qwen-plus or qwen3-max instead.
Pricing: $1.20 input / $6.00 output per MTok on the standard tier. Long-prompt tiers may price higher per Bailian's published schedule. TheRouter routes to the cheaper of bailian-cn / bailian-sg per request.
