Configuring Thinking Levels and Reasoning Modes in Qwen Models

Users are discussing how to configure the "thinking" (reasoning) levels and budgets for Qwen models, which support modes like Hybrid (toggled per request) and Thinking-only. These configurations can be adjusted dynamically per request using parameters like `enable_thinking` and `reasoning_effort`. Allowing users to control reasoning effort helps balance computational cost and response quality for local LLM deployments. This flexibility makes Qwen models highly adaptable for tasks ranging from quick conversational replies to complex, multi-step problem solving. The thinking level can be sent per request in `chat_template_kwargs` using parameters such as `enable_thinking`, `reasoning_effort`, and `preserve_thinking` without requiring a server restart. Depending on the model, thinking is either always active (Thinking-only) or toggleable (Hybrid).
