简介

BFS Best Face Swap 是一款基于 MIT 协议的开源换脸模型，专注于高保真度的面部特征迁移。与传统的简单滤镜不同，它在保持目标人物面部结构的同时，能更自然地融合光影与皮肤纹理，有效降低了换脸后常见的“违和感”。该模型上手门槛极低，非常适合需要快速生成高质量人像素材的创作者。如果你在使用 Stable Diffusion 等工具时觉得内置的换脸插件效果不够细腻，BFS 提供了一个更轻量且精准的替代方案，适用于电商模特替换、虚拟角色创作等实际场景。

核心亮点

  • 高保真面部迁移，光影融合自然不违和
  • MIT 开源协议，开发者可自由集成与商用
  • 操作门槛低，快速生成高质量人像素材
  • 完美适配虚拟角色创作与电商模特替换

🧬 BFS — Best Face Swap (Qwen Image Edit, Flux 2 Klein, Krea 2)

The BFS (Best Face Swap) LoRA series was created for Qwen Image Edit 2509/2511, Flux 2 Klein 4b/9b, and Krea 2, designed to perform high-fidelity face, head, and full-person swaps with natural tone blending and consistent lighting.

Each version focuses on a different level of replacement, from subtle face swaps to full head transfers.
Use each LoRA with its matching base model and workflow. Krea 2 head/body workflows are included in the workflows folder.

👉 Workflows for all BFS versions can be downloaded here:

🔹 Versions Overview

| Version | File(s) | Description |
|---|---|---|
| BFS Face V1 – 2509 | bfs_face_v1_qwen_image_edit_2509.safetensors | Swaps only the face. Preserves target hair, lighting, and background. |
| BFS Head V1 – 2509 | bfs_head_v1_qwen_image_edit_2509.safetensors | Full head swap with natural blending between head/hair and target body. |
| BFS Head V2 – 2509 | bfs_head_v2_qwen_image_edit_2509.safetensors | Improved skin tone matching, pose alignment, and anatomical consistency. |
| BFS Head V3 – 2509 (Recommended) | bfs_head_v3_qwen_image_edit_2509.safetensors | Stable and accurate. Input order is inverted (body first, then face). |
| BFS Head V4 – 2509/2511 | bfs_head_v4_qwen_image_edit_2509.safetensors | Stronger expression transfer and robustness. Inverted input order. |
| BFS Head V5 – 2511 (Recommended) | bfs_head_v5_2511_original.safetensors<br>bfs_head_v5_2511_merged_version_rank_16_fp16.safetensors<br>bfs_head_v5_2511_merged_version_rank_32_fp32.safetensors | Latest release for 2511 workflows. Inverted input order. See details below. |
| BFS Head V1 – Flux 2 Klein 4/9b (Recommended) | bfs_head_v1_flux-klein_4b.safetensors<br>bfs_head_v1_flux-klein_9b_step3500_rank128.safetensors<br>bfs_head_v1_flux-klein_9b_step3750_rank64.safetensors | Inverted input order. See details below. |
| BFS Head Swap V1.1 – Krea 2 | bfs_head_swap_v1.1_krea2.safetensors | Updated Krea 2 head swap release. Replaces the previous V1 file. |
| BFS Body Swap V1 – Krea 2 (Experimental) | bfs_body_swap_v1_krea2.safetensors | Replaces the person with the reference person. Pose transfer may not always match exactly. |

🧠 BFS Head V5 details (2511)

This release includes multiple variants:

  • 100% original: direct result of training for 5,500+ steps on model 2511
  • Merged versions: a merge of BFS Head V4 (2509) into the 2511-trained original

In my evaluation, the merged version performs better, especially at reproducing a wider range of expressions.
It is not perfect yet, but it indicates we are moving in the right direction.

🧪 Krea 2 Head and Body Swap

BFS Head Swap V1.1

This is the updated Krea 2 head swap release and replaces bfs_head_swap_v1_krea2.safetensors.

Trigger prompt:

code
head_swap: replace the head with the reference head.

Workflow: workflows/Head Swap Krea 2 - V1 Simple Workflow.json

BFS Body Swap V1 (Experimental)

This is an experimental version. The pose will not always be copied exactly from the original image.

Trigger prompt:

code
body_swap: replace the person with the reference person.

To also change the background, append this below the trigger prompt:

code
BG: [describe the new background]

You can combine the body swap LoRA with the Krea 2 head swap LoRA to improve head identity. As a starting point, use both LoRAs at 0.5 strength, then adjust based on your own tests.

Workflow: workflows/Body Swap Krea 2 - V1 Simple Workflow.json

Feel free to experiment and post your results.

💬 Prompts

🧠 BFS Face V1

Base prompt:

code
face swap face from Image 1 to Image 2.

Alternative:

code
face swap face from Image 1 to Image 2. swap only the face (not the hair), match the skin tone to Image 2, keep Image 2 pose and lighting.

---

🧩 BFS Head V1 – 2509 (Likely works with 2511)

Base prompt:

code
head swap from Image 1 to Image 2

Alternatives:

code
head swap from Image 1 to Image 2 with perfect skin match
Head swap from Image 1 to Image 2, keep all facial details and hair from Image 1, blend naturally with Image 2’s body.
head swap face from Image 1 to Image 2, keep all facial details and hair from Image 1, blend naturally with Image 2’s body, remove all hair of Image 2 and replace by hair from Image 1 and keep the same expression and head proportion as in Image 2

---

🧬 BFS Head V2 – 2509 (Likely works with 2511)

code
head swap, transfer head from Image 1 to Image 2

---

⚡ BFS Head V3 – 2509 (Recommended) (Likely works with 2511)

code
head_swap: start with Picture 1 as the base image, keeping its lighting, environment, and background. remove the head from Picture 1 completely and replace it with the head from Picture 2. ensure the head and body have correct anatomical proportions, and blend the skin tones, shadows, and lighting naturally so the final result appears as one coherent, realistic person.

---

⚡ BFS Head V4 – 2509 (Likely works with 2511)

code
h34d_sw4p: replace the head of Picture 1 by the head from Picture 2, strictly preserving the identity, facial features (eyes, nose, mouth), and skin texture of Picture 2. ensure the new head mimics the identical expression, angle, and rotation found in Picture 1.

---

⚡ BFS Head V5 – 2511 (Recommended)

code
head_swap: start with Picture 1 as the base image, keeping its lighting, environment, and background. remove the head from Picture 1 completely and replace it with the head from Picture 2, strictly preserving the hair, eye color, and nose structure of Picture 2. copy the eye direction, head rotation, and micro-expressions from Picture 1. high quality, sharp details, 4k
