Qwen 3 Coder API: coding-specialized model at an ultra-low price

Qwen 3 Coder is Alibaba's coding-specialized large language model, built for code generation, debugging, and day-to-day software engineering. With a 262K-token context window and pricing of $0.17 per 1M input tokens and $1.05 per 1M output tokens, it gives teams a budget-friendly way to add an AI coding assistant to editors, CI pipelines, and developer tools.

Through YepAPI you call Qwen 3 Coder with a single OpenAI-compatible API key. That same key also reaches dozens of other models plus SEO, SERP, and web-scraping endpoints, so you can pair code generation with data collection in one account.

What is Qwen 3 Coder?

Qwen 3 Coder is a code-focused model from Alibaba's Qwen family, optimized for software engineering rather than open-ended conversation. It handles code generation, multi-language refactoring, bug fixing, and code review, and its 262,144-token context window lets it reason over large repositories, long diffs, and entire modules at once. With a maximum output of 8,192 tokens per response, it is well suited to producing complete functions, test files, and focused fixes. Its standout trait is price: at $0.17 input and $1.05 output per 1M tokens, it makes high-volume automated coding workflows affordable.

Build with Qwen 3 Coder via YepAPI

Send requests to the OpenAI-compatible /v1/ai/chat endpoint with your YepAPI key. Because the schema matches the OpenAI Chat Completions format, existing SDKs and agent frameworks work by changing only the base URL and model name. Stream completions into your IDE, wire it into code-review bots, or run it inside autonomous coding agents. One key also unlocks other models and YepAPI's SEO, SERP, and scraping APIs, so a single integration can generate code and gather data side by side.

Qwen 3 Coder API pricing — $0.17 / $1.05 per 1M tokens

Qwen 3 Coder costs $0.17 per 1M input tokens and $1.05 per 1M output tokens. That low rate is the model's defining feature: you can review thousands of files, run continuous code-generation jobs, or power high-volume developer tooling without large bills. Usage is billed per token, so quick fixes cost a fraction of a cent and you only pay for what you process.

Qwen 3 Coder for automated code generation

The model fits CI/CD and developer-tooling workloads where cost-per-call matters: generating boilerplate, scaffolding services, writing unit tests, and reviewing pull requests at scale. The 262K context lets it ingest a whole module plus its tests before suggesting changes, while the low price makes it practical to run on every commit. It is a strong default for coding agents that loop many times per task.
