# BRIA 2.3 T5: Text-to-Image Model for Commercial Licensing

Bria AI 2.3 T5 is an alternative text-to-image model for specific commercial applications. It exclusively uses T5 for text embedding, enabling support for text prompts of unlimited length. This model matches 2.3's photorealism, with a 4% decrease in prompt alignment and 7% decrease in aesthetics. Like all Bria models, 2.3 T5 upholds ethical standards, excludes copyrighted and harmful content, and comes with full legal liability coverage. While 2.3 T5 is preferable when T5 embedding or support for longer prompts is specifically required, our recommended model for most use cases remains [Bria 2.3](https://huggingface.co/briaai/BRIA-2.3), especially given its compatibility with Bria's ControlNets and Adapters.

# What's New

Bria AI 2.3 T5 supports text prompts of unlimited length. Additionally, unlike BRIA 2.3, it exclusively uses T5 for text embedding, eliminating biases associated with CLIP.

### Code example using Diffusers 


```
pip install diffusers, torch, huggingface_hub
```


```py
from diffusers import DiffusionPipeline
from huggingface_hub import snapshot_download
import torch
import os, sys

pipeline_path = snapshot_download(repo_id='briaai/BRIA-2.3 T5')    
sys.path.append(pipeline_path)
from ella_xl_pipeline import EllaXLPipeline
    
pipe = DiffusionPipeline.from_pretrained("briaai/BRIA-2.3", torch_dtype=torch.float16, use_safetensors=True)
pipe.load_lora_weights(f'{pipeline_path}/pytorch_lora_weights.safetensors')
pipe.fuse_lora()
pipe.unload_lora_weights()
pipe.to("cuda")
pipe = EllaXLPipeline(pipe,f'{pipeline_path}/pytorch_model.bin')

prompt = "A portrait of a Beautiful and playful ethereal singer, golden designs, highly detailed, blurry background"
negative_prompt = "Logo,Watermark,Text,Ugly,Morbid,Extra fingers,Poorly drawn hands,Mutation,Blurry,Extra limbs,Gross proportions,Missing arms,Mutated hands,Long neck,Duplicate,Mutilated,Mutilated hands,Poorly drawn face,Deformed,Bad anatomy,Cloned face,Malformed limbs,Missing legs,Too many fingers"

images = pipe(prompt=prompt, negative_prompt=negative_prompt, height=1024, width=1024).images[0]
```


### Some tips for using our text-to-image model at inference: 


1. You must set `pipe.force_zeros_for_empty_prompt = False`
2. Using negative prompt is recommended.
3. We support multiple aspect ratios, yet resolution should overall consists approximately `1024*1024=1M` pixels, for example:
`(1024,1024), (1280, 768), (1344, 768), (832, 1216), (1152, 832), (1216, 832), (960,1088)`
4. If you need speed - try the BRIA 2.3 Fast which achieve 75% reduced inference time 
5. For 2.3 T5, use 30-50 steps (higher is better)
6. For 2.3 T5, use `guidance_scale` of 5.0 or 7.5
