Overview
Qwen3.5-9B is a compact 9B parameter reasoning model with a 262K token native context length, designed for strong reasoning performance while remaining extremely cost-efficient. Despite its small size, it performs remarkably well on complex tasks and in Qwen's benchmarks outperformed the, much larger, GPT-OSS-120 model.
Thinking Mode:
This model reasons step-by-step before responding by default.
This model does not support graduated thinking levels. Parameters such as reasoning_effort are not supported and will have no effect.
Reasoning efforts
- Supported:
none,minimal,low,medium,high,xhigh,max
