Prompt Enhancer (Flux2)<div style="font-size: 0.8em"><div id="Y7_shortdesc" style="margin-bottom: 15px;">Takes a basic prompt and enhances (upsamples) it for Flux.2</div></div><div style="font-size: 0.8em"><div style="margin-bottom: 8px; margin-left: 0px; font-size: 12px;">ComfyUI's Flux.2 workflows do not implement any prompt upsampling that is seen and used in some of Black Forest Lab demos, so what you write is what you get. This uses the Qwen3-8B model to enhance prompts with support for thinking mode.</div></div><div style="font-size: 0.8em"><div style="margin-bottom: 8px; margin-left: 0px; font-size: 12px;">Inputs:</div></div><div style="font-size: 0.8em"><div style="margin-bottom: 8px; margin-left: 20px; font-size: 12px;">- <code style="border: 1px solid #666; border-radius: 3px; padding: 0px 1px; font-family: monospace; display: inline-block;">prompt</code>: Your basic text prompt to enhance</div></div><div style="font-size: 0.8em"><div style="margin-bottom: 8px; margin-left: 20px; font-size: 12px;">- <code style="border: 1px solid #666; border-radius: 3px; padding: 0px 1px; font-family: monospace; display: inline-block;">llm_name</code>: LLM model to use (currently only Qwen3-8B, more to be added)</div></div><div style="font-size: 0.8em"><div style="margin-bottom: 8px; margin-left: 20px; font-size: 12px;">- <code style="border: 1px solid #666; border-radius: 3px; padding: 0px 1px; font-family: monospace; display: inline-block;">quantization</code>: Model precision.
