P-Q-Image-2.1 is a set of LoRA adapters that let 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, 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. No custom nodes are needed. Update ComfyUI to a version with native Qwen-Image-2.1 support.

For prompting guides, benchmarking, and limitations, see the original repo 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. Use the base checkpoint, not the Turbo one.

Workflows

Drag a file from 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.
