BFS-Best-Face-Swap is an open-weight image model from Alissonerdx, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
🧬 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: Head/Face Swap Workflow — Qwen Image Edit 2509 (Civitai) 🔹 Versions Overview 🧠 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 bfsheadswapv1krea2.safetensors. Trigger prompt: 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: To also change the background, append this below the trigger prompt: 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.

Using it via the API
Once AxForge deploys bfs-best-face-swap for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (bfs-best-face-swap below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/images/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"bfs-best-face-swap","prompt":"a red bicycle","size":"1024x1024"}'
