# curated_nunchaku_qwen_lightning_txt2img_gpt5_nano_prompt

Curated workflow skill generated from `Nunchaku Qwen Lightning txt2img + GPT5 Nano Prompt.json`.

## Capability Family

- `txt2img`

## Inputs

- Optional runtime overrides supported by `run(...)`:
  - `prompt`
  - `negative_prompt`
  - `width`, `height`
  - `seed`, `steps`, `cfg`
  - `sampler_name`, `scheduler`, `denoise`
  - `server`, `headers`, `api_prefix`

## Outputs

- Returns JSON with:
  - `status`
  - `prompt_id`
  - `output_images` (includes image/video entries reported by Comfy history)

## Model Requirements

- `clip`: `qwen_2.5_vl_7b_fp8_scaled.safetensors` -> `models/clip`
- `vae`: `qwen_image_vae.safetensors` -> `models/vae`

## Custom Node Requirements

- `comfyui-nunchaku`
