TBAC-UniImage-3B
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 serves as the understanding module, while the SANA-1600M acts as the generation module. The conditions for generation are originate from representations of different Qwen2.5-VL-3B-Instruct layers.

| BILP-3o | Qwen2.5-VL-3B-Instruct | 0.81 | 79.36 |
| Qwen2.5-VL-7B-Instruct | 0.83 | 80.73 | |
| BAGEL | MoT-7B | 0.82 | - |
| Show-o2 | Qwen2.5-1.5B-Instruct | 0.73 | 85.02 |
| Qwen2.5-7B-Instruct | 0.76 | 86.14 | |
| Tar | Qwen2.5-1.5B-Instruct | 0.76 | 82.96 |

TIIF-Bench
Image Editing Performance
The input image is processed by the Qwen2.5-VL image encoder and then fed into the MLLM along with text and learnable queries. We use only the learnable queries, which have fused the multimodal information, as the generative condition, without directly incorporating any image VAE representations like other works. Despite this, the model still achieves promising multimodal understanding and consistency performance in Image Editing tasks.

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.
