Model Card

Expand Image is an image outpainting model from Bria AI that extends an image beyond its original borders by generating new pixels to fit a wider or taller composition. It takes an input image (JPEG, PNG, or WEBP, as base64 or a public URL) and returns a larger image with the original content kept in place.

The target shape can be set with a preset aspect ratio such as 1:1, 3:2, 4:5, 9:16, or 16:9, or with a custom ratio between 0.5 and 3.0. Typical uses are adapting creatives to different social media placements, turning a portrait image into a landscape banner, and adding background around a subject in product or marketing visuals.

Bria trains its models on licensed data and positions them for commercial use, which suits teams building design, brand, or ecommerce pipelines that need to reframe many assets without editing each one by hand.

FIBO

FIBO is a text-to-image model from Bria AI, launched in November 2025. Rather than encoding a prompt directly, an accompanying language model expands a short prompt into a structured JSON specification covering visual attributes such as lighting, camera angle, composition, and color, then generates the image from that specification and returns the JSON alongside it. FIBO has 8 billion parameters and is trained on structured JSON captions running to 1,000+ words, using licensed images from more than 20 content partners, including Getty Images and Envato. FIBO also supports a refine mode that changes only the attributes named in a follow-up instruction while holding the rest of the specification fixed, and an inspire mode that derives a JSON specification from a reference image. Bria reports it leads open alternatives on image-text alignment and aesthetics in PRISM-style evaluations, suited to teams that need reproducible output such as brand or product imagery.

Image 3.2

Image 3.2 is Bria AI's text-to-image model for commercial use, an update to Bria 3.1 in the company's Bria 3 series. It runs on a 4 billion parameter rectified-flow transformer with a T5 text encoder, about a third the size of the 12 billion parameter open-weight models it's compared against, while Bria reports aesthetics and prompt adherence on par with those larger models. The model is trained entirely on licensed image data, avoiding copyrighted characters, logos, trademarks, and public figures in its training set. Text rendering was a focus for this release. Bria's own benchmark shows OCR accuracy for short in-image text (one to six words) rising from 5% in version 3.1 to 70% in version 3.2. The smaller parameter count also brings faster fine-tuning, about 2x quicker on L40S and A100 GPUs, useful for teams adapting the model to a specific brand or product style.
