Text-to-image and image editing
**P-Q-Image-2.1** is a set of LoRA adapters that let
[`Qwen/Qwen-Image-2.1`](https://huggingface.co/Qwen/Qwen-Image-2.1) generate
and edit images in only 6 steps (v0.2), or 5 or 8 steps (v0.1). The adapters load
on top of the base model, so the pipeline, text encoder, and VAE stay unchanged.
This repository is the ComfyUI export of the original repo
[`PrunaAI/P-Q-Image-2.1`](https://huggingface.co/PrunaAI/P-Q-Image-2.1),
plus example workflows for text-to-image and image editing.
The adapters load with the native `LoraLoaderModelOnly` node on top of the
Qwen-Image-2.1 base checkpoint from
[Comfy-Org/Qwen-Image-2.1](https://huggingface.co/Comfy-Org/Qwen-Image-2.1).
No custom nodes are needed. Update ComfyUI to a version with native Qwen-Image-2.1 support.
## Versions
| Version | Variant | File | Steps |
|---|---|---|:---:|

For prompting guides, benchmarking, and limitations, see the original repo
[`PrunaAI/P-Q-Image-2.1`](https://huggingface.co/PrunaAI/P-Q-Image-2.1).
## Setup
Place the files in the following folders:
```
ComfyUI/
└── models/
├── diffusion_models/
│ └── qwen_image_2.1_int8_convrot.safetensors (or qwen_image_2.1_bf16.safetensors)
├── loras/
│ └── p_q_image_2.1_6_steps_v0.2_comfyui_bf16.safetensors
├── text_encoders/
│ └── qwen3vl_8b_int8_convrot.safetensors
└── vae/
└── qwen_image_2.1_vae_bf16.safetensors
```
The base model, text encoder and VAE come from
[Comfy-Org/Qwen-Image-2.1](https://huggingface.co/Comfy-Org/Qwen-Image-2.1).
Use the base checkpoint, not the Turbo one.
## Workflows
Drag a file from [`workflows/`](workflows) into ComfyUI.
| Workflow | Adapter |
|---|---|
| `pruna_q_image_2.1_v0.2_6step_t2i.json` | v0.2 `6-steps` (switch `lora_name` to `6-steps-upsampled`) |
| `pruna_q_image_2.1_v0.2_6step_image_edit.json` | v0.2 `6-steps` (switch `lora_name` to `6-steps-upsampled`) |
| `pruna_q_image_2.1_v0.1_8step_t2i.json` | v0.1 `8-steps` |
| `pruna_q_image_2.1_v0.1_8step_image_edit.json` | v0.1 `8-steps` |
| `pruna_q_image_2.1_v0.1_5step_t2i.json` | v0.1 `5-steps` |
| `pruna_q_image_2.1_v0.1_5step_image_edit.json` | v0.1 `5-steps` |
Each workflow loads one adapter at strength **1.0** and samples with `euler`,
cfg **1**, and the matching `ManualSigmas` schedule.
## Sampling settings
Use the sigma schedule that matches the adapter. Do not mix v0.1 and v0.2
schedules.
| Adapter | ManualSigmas |
|---|---|
| v0.2, 6 steps | `1.0, 0.961054, 0.918949, 0.769302, 0.545554, 0.222292, 0` |
| v0.1, 8 steps | `1.0, 0.933333, 0.857143, 0.769231, 0.666667, 0.545455, 0.4, 0.222222, 0` |
| v0.1, 5 steps | `1.0, 0.94, 0.857143, 0.666667, 0.4, 0` |
- **cfg 1**, no negative prompt, sampler `euler`, LoRA strength **1.0**.
- The adapters were trained at 1K resolution only.
