# Bria Fibo Text-to-image models have mastered imagination - but not control. FIBO changes that. FIBO is trained on structured JSON captions up to 1,000+ words and designed to understand and control different visual parameters such as lighting, composition, color, and camera settings, enabling precise and reproducible outputs. With only 8 billion parameters, FIBO provides a new level of image quality, prompt adherence and proffesional control. FIBO is trained exclusively on a structured prompt and will not work with freeform text prompts. you can use the [FIBO-VLM-prompt-to-JSON](https://huggingface.co/briaai/FIBO-VLM-prompt-to-JSON) model or the [FIBO-gemini-prompt-to-JSON](https://huggingface.co/briaai/FIBO-gemini-prompt-to-JSON) to convert your freeform text prompt to a structured JSON prompt. > [!NOTE] > Avoid using freeform text prompts directly with FIBO because it does not produce the best results. Refer to the Bria Fibo Hugging Face [page](https://huggingface.co/briaai/FIBO) to learn more. ## Usage _As the model is gated, before using it with diffusers you first need to go to the [Bria Fibo Hugging Face page](https://huggingface.co/briaai/FIBO), fill in the form and accept the gate. Once you are in, you need to login so that your system knows you’ve accepted the gate._ Use the command below to log in: ```bash hf auth login ``` ## BriaFiboPipeline [[autodoc]] BriaFiboPipeline - all - __call__
