 | `QWEN_CODE_MAX_OUTPUT_TOKENS`  | Overrides the default maximum output tokens per response. When not set, Qwen Code uses an adaptive strategy: starts with 8K tokens and automatically retries with 64K if the response is truncated. Set this to a specific value (e.g., `16000`) to use a fixed limit instead. | Takes precedence over the capped default (8K) but is overridden by `samplingParams.max_tokens` in settings. Disables automatic escalation when set. Example: `export QWEN_CODE_MAX_OUTPUT_TOKENS=16000`                                                                                                                                                                                                                                                                            |
