We swapped our coding agent onto the Qwen3 Coder Next API and multi-file refactors started landing green on the first pass far more often.
Qwen3 Coder Next is the next-generation coding model in the Alibaba Qwen3 Coder line, tuned for agentic coding, refactoring, debugging, and diff review. Served on RouterBase over an OpenAI-compatible endpoint at $0.17 / 1M input and $1.275 / 1M output, 15% below list.

Qwen3 Coder Next API - Next-Gen Agentic Coding
The Qwen3 Coder Next API runs Qwen3 Coder Next, the next-gen model in the Alibaba Qwen3 Coder line, built for agentic coding.
The Qwen3 Coder Next API serves Alibaba Qwen3 Coder Next, the newest generation of the Qwen3 Coder family. The model was tuned for the software loop itself: generating functions, refactoring modules, tracing bugs, reviewing diffs, and driving agentic workflows that plan, call tools, and edit code across a repository. You reach the Qwen3 Coder Next API through RouterBase over the OpenAI chat-completions protocol, so your existing client works unchanged and one key covers the whole catalog.
Under the hood, Qwen3 Coder Next was built for the work coding teams actually ship: IDE assistants, autonomous coding agents, review bots, and batch refactoring pipelines. Billing is $0.17 per 1M input tokens and $1.275 per 1M output tokens, 15% below the list rate of $0.20 in and $1.50 out, with no per-request fee. Tool calls come back in the standard OpenAI schema, so you can wire the Qwen3 Coder Next API into an agent loop or a CI job without provider-specific glue.
What the Qwen3 Coder Next API gives you
A coding model that ships real diffs.
Next-gen coder model
The Qwen3 Coder Next API runs the newest generation of the Qwen3 Coder line, tuned end to end for code generation, refactoring, and debugging on real repositories.
Agentic coding loops
Plan, call tools, edit, and re-test: the Qwen3 Coder Next API returns function calls in the standard OpenAI schema, so coding agents run multi-step tasks without custom parsing.
Long coding sessions
Large files, test suites, and tool traces stay in play across a session, so the Qwen3 Coder Next API keeps its bearings deep into a repository-scale task.
Review and refactor
Diff review, bug tracing, and batch refactoring are first-class jobs for the Qwen3 Coder Next API, which was tuned on the software loop rather than general chat alone.
Structured output
The Qwen3 Coder Next API returns reliable JSON and schema-bound responses, so codemods, extraction, and pipeline steps stay easy to parse.
Streaming, per token
The Qwen3 Coder Next API streams tokens as they generate and bills per token at $0.17 in and $1.275 out, 15% below list, with no request fee.
Get going
First call to the Qwen3 Coder Next API in three steps
Wire it once, then stream.
Create a key
One RouterBase key reaches the Qwen3 Coder Next API and every other model in the catalog, so there is nothing provider-specific to set up.
Point your client
Send any OpenAI client to routerbase.com/v1 with model=qwen/qwen3-coder-next and a messages array; the Qwen3 Coder Next API answers on the same chat-completions shape.
Stream and watch usage
The model streams tokens as they generate and returns token usage per response, so cost and latency stay visible on every call to the Qwen3 Coder Next API.
Pay only for what you use
RouterBase passes through partner-tier pricing. Compared against the model's official published API rate.

One run at the default settings (Input (per 1M)) costs $0.170.With $1 you can run this model approximately 5 times.
Official price = Alibaba Qwen list rate for Qwen3 Coder Next ($0.20 per 1M input, $1.50 per 1M output). RouterBase serves the Qwen3 Coder Next API at $0.17 / $1.275, 15% below list.
Teams building on the Qwen3 Coder Next API
Coding agents and review bots behind one call.
Tool calls come back in the standard schema, so our agent loop ran on the Qwen3 Coder Next API the same afternoon we created the key.
Review comments from the Qwen3 Coder Next API read like a careful senior engineer wrote them, and the diffs it proposes actually apply.
At $0.17 in and $1.275 out, the Qwen3 Coder Next API let us run agentic coding jobs nightly without the bill spiking.
Streaming from the Qwen3 Coder Next API is smooth, so our editor extension renders completions token by token with no buffering tricks.
We route codemods and JSON extraction through the Qwen3 Coder Next API and the structured output parses clean every run.
Long sessions hold together - the Qwen3 Coder Next API kept a whole service plus its tests in play through a two-hour refactor.
Moving from another provider to the Qwen3 Coder Next API was one string change; the OpenAI shape did not move at all.
Our PR bot standardized on the Qwen3 Coder Next API because the review quality held steady as we scaled it across repos.
