Qwen: Qwen3 Coder 480B A35B (free)

Qwen3 Coder 480B A35B is a text-only model from Qwen with a context window of just over one million tokens and a maximum completion length of 262,000 tokens, both unusually large figures. It accepts text input, supports tool use, and does not include a built-in reasoning mode. Structured output support is unconfirmed. The combination of long context and tool support makes it broadly suited to coding workflows, document analysis, and agentic tasks that require reading large codebases or files in a single pass. The model is currently free, with no input or output costs. That pricing alone makes it worth testing for teams managing inference budgets. The caveat is real, however: there is no independent benchmark coverage to anchor performance expectations, so any assessment of quality is currently anecdotal. Users who need a proven, scored model before committing should treat this as a trial candidate rather than a primary choice until benchmark data becomes available.
