QwenVL-F Prompt Enhancer is a ComfyUI node in the QwenVL-F category from ComfyUI-QwenVL-F. Inputs: model_name, quantization, attention_mode, use_torch_compile…

Fork of ComfyUI-QwenVL: Qwen-VL nodes (Qwen2.5-VL / Qwen3-VL, Transformers and GGUF backends) for text generation, image understanding, and video analysis. Adds local-only model discovery — models are picked from models/text_encoders and models/LLM with no automatic downloading — plus explicit mmproj selection, up to 3 image inputs on the Advanced

QwenVL-F Prompt Enhancer

Name	Type	Default	Description
model_name	COMBO	(no models found — see console)	Pick a Transformers checkpoint already present under models/text_encoders or models/LLM. Nothing is downloaded automatically — copy the model folder in yourself, then reload ComfyUI.
quantization	COMBO	None (FP16)	Precision vs VRAM. FP16 gives the best quality if memory allows; 8-bit suits 8–16 GB GPUs; 4-bit fits 6 GB or lower but is slower.
attention_mode	COMBO	auto	auto tries flash-attn v2 when installed and falls back to SDPA. Only override when debugging attention backends.
use_torch_compile	BOOLEAN	false	Enable torch.compile('reduce-overhead') on supported CUDA/Torch 2.1+ builds for extra throughput after the first compile.
device	COMBO	auto	Choose where to run the model: auto, cpu, mps, or cuda:x for multi-GPU systems.
prompt_text	STRING		Prompt text to enhance. Leave blank to just emit the preset instruction.
enhancement_style	COMBO	📝 Enhance	6 options: 📝 Enhance, 📝 Refine, 📝 Creative Rewrite, 📝 Detailed Visual, 📝 Artistic Style, 📝 Technical Specs
custom_system_prompt	STRING		—
max_tokens	INT	25632–1024	—
temperature	FLOAT	0.700.1–1	—
top_p	FLOAT	0.900–1	—
repetition_penalty	FLOAT	1.100.5–2	—
keep_model_loaded	BOOLEAN	true	—
