# TBAC-UniImage-3B

[Arxiv](https://arxiv.org/abs/2508.08098) | [Github](https://github.com/DruryXu/TBAC-UniImage)

## Overview
This repository contains the official model checkpoints of **TBAC-UniImage-3B**, an unified understanding and generation model developed by Basic Algorithm Center, Platform and Content Group, Tencent.

Our model is composed of two components: the [Qwen2.5-VL-3B-Instruct](https://huggingface.co/Qwen/Qwen2.5-VL-3B-Instruct) serves as the understanding module, while the [SANA-1600M](https://huggingface.co/Efficient-Large-Model/Sana_1600M_512px_diffusers) acts as the generation module. The conditions for generation are originate from representations of different Qwen2.5-VL-3B-Instruct layers.

### Few Prompts Used in Teaser

- A serene photoaraph of a ainder and white cat sittina in a sunlit arassy field. The catis positioned sliahtiv to the riaht. aazing upwards with a calm expression. Its fur is a soft orande with distinct white patches on its chest and face. The foreground features out-of-focus blades of grass, creating a dreamy bokeh effect. The background is a blurred mix of soft greens and browns, suggesting a natural outdoor setting. The lighting is warm and golden, highlighting the cat's fur and casting gentle shadows. The image has a shallow depth of field, emphasizing the cat while the background remains softly blurred. Photorealistic, tranquil, natural lighting, warm color palette, high contrast, intimate, peaceful atmosphere.
- a chinese rabbit made of white ceramic with blue ink, stunning intricate designs, (geometric and floral patterns, fine art))
- nighttime view of a gothic horror castle with vivid colors and a wood press style, dark fantasy
- few palm tree and an old car, simple background, pop art style
- Steampunk architecture in the forest, reactor, rusty green color scheme with Studio Ghibli style, lots of details, mechanical, green, forest, trees, moss, 8K, Unreal Engine, C4D rendering, Ultra HD details
- An astronaut holding a stop sign on the moon.

## Limitations
For a better experience, please use the text-to-image mode. The image-text-to-image capability is currently weaker (but you can still try it).
