Qwen3 Coder Plus
VerifiedOpen-weight coder built for million-token codebases and complex tasks.
About Qwen3 Coder Plus
Qwen3 Coder Plus follows the standard transformer architecture used across the Qwen series. Its open-weight release allows full local deployment and fine-tuning. The 1,000,000-token context window enables the model to ingest entire large projects in a single pass.
The model is optimized for code-related tasks including generation, completion, refactoring, and analysis. Its text modality supports direct handling of source files, documentation, and technical specifications without additional modalities.
Typical usage includes automated code review, large-scale codebase migration, and interactive debugging sessions. Developers commonly integrate it into IDEs or custom pipelines where long-context understanding improves accuracy on repository-level problems.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "qwen/qwen3-coder-plus",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: qwen/qwen3-coder-plus
