Qwen3 Coder Next
VerifiedOpen-weight LLM built for large-scale code tasks.
About Qwen3 Coder Next
Qwen3 Coder Next follows a transformer architecture optimized for long-context text processing. Its open-weight release allows developers to run and fine-tune the model locally or on private infrastructure without usage restrictions.
The 262k token context enables the model to ingest entire repositories or lengthy technical documents in a single pass. This design supports coherent reasoning across multiple files and extended code histories.
Typical usage includes code completion, refactoring, documentation generation, and debugging within integrated development environments. Teams also deploy it for automated code review and migration projects where large context retention is essential.

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-next",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: qwen/qwen3-coder-next
Editor's verdict
Qwen3 Coder Next is Alibaba Qwen's open-weight language models with a 262K-token context window.
At $0.80 per 1M output tokens, it is very cost-efficient for its class.
As an open-weight model you can self-host it or call it through a hosted API.
Best suited to strong coding specialization and very large context window for codebases.
