FIBO-Edit brings the power of structured prompt generation to image editing.
Built on Fibo's foundation and of JSON-native control, FIBO-Edit delivers precise, deterministic, and fully controllable edits. No ambiguity, no surprises.
Most image editing models rely on loose, ambiguous text prompts, but not FIBO-Edit. FIBO-Edit introduces a new paradigm of structured control, operating on structured JSON inputs paired with a source image (and optionally a mask). This enables explicit, interpretable, and repeatable editing workflows optimized for professional production environments.
Developed by Bria AI, FIBO-Edit prioritizes transparency, legal safety, and granular control: ranking among the top models in open benchmarks for prompt adherence and quality.
📄 Technical report coming soon. For architecture details, see FIBO.
FIBO-Edit is natively built on Visual GenAI Language (VGL). VGL standardizes image generation by replacing vague natural language descriptions with explicit, human-machine-readable JSON. By disentangling visual elements—such as lighting, composition, style, and camera parameters—VGL transforms editing from a probabilistic guessing game into a deterministic engineering task. Fibo-Edit reads these structured blueprints to perform precise updates without prompt drift, ensuring the output matches your exact specifications.
Fibo Edit is available everywhere you build, either as source-code and weights, ComfyUI nodes or API endpoints.

The repository supports two modes for generating structured JSON prompts:
API Mode (default): Uses Gemini as the VLM. Set your API key:
export GEMINI_API_KEY="your-api-key"
Local Mode: Uses a local VLM model (briaai/FIBO-edit-prompt-to-JSON) via diffusers ModularPipelineBlocks. Runs locally on your GPU.
Note: Local VLM mode does not support mask-based editing. Use API mode for masked edits.
```python
import torch
from diffusers import BriaFiboEditPipeline
from PIL import Image
from src.edit_promptify import get_prompt
# Generate structured JSON using API mode
image = Image.open("photo.jpg")
mask_image = Image.open("mask.jpg").convert("L")
edit_json = get_prompt(image=image, instruction="make it look vintage", mask_image=mask_image)
# Use with Fibo Edit
pipe = BriaFiboEditPipeline.from_pretrained(
"briaai/Fibo-Edit",
torch_dtype=torch.bfloat16,
)
pipe.to("cuda")
result = pipe(
image=image,
mask=mask,
prompt=edit_json,
num_inference_steps=50,
guidance_scale=5
).images[0]
result.save("edited.png")
```
```python

from diffusers import BriaFiboEditPipeline

result.save("edited.png")

FIBO supports multiple VLM options for generating structured JSON prompts:
To use Gemini as VLM backbone for FIBO, follow these instructions:
Obtain a Gemini API Key
Sign up for the Google AI Studio (Gemini) and create an API key.
Set the API Key as an Environment Variable
Store your Gemini API key in the GEMINI_API_KEY environment variable:
export GEMINI_API_KEY=your_gemini_api_key
You can add the above line to your .bashrc, .zshrc, or similar shell profile for persistence.
# API mode is the default
edit_json = get_prompt(image=image, instruction="your edit instruction")
# Or explicitly specify
edit_json = get_prompt(
image=image,
instruction="your edit instruction",
vlm_mode="api",
model="gemini/gemini-2.5-flash"
)
Use the briaai/FIBO-edit-prompt-to-JSON model locally.
edit_json = get_prompt(
image=image,
instruction="your edit instruction",
vlm_mode="local",
model="briaai/FIBO-edit-prompt-to-JSON"
)
Note: Local mode does not support mask-based editing.
