# TIPO: Text to Image with text presampling for Prompt Optimization
500M LLaMA arch model trained for TIPO.<br>
Tech Report: https://arxiv.org/abs/2411.08127
## Introduction
In this project, we introduce "TIPO" (**T**ext to **I**mage with text presampling for **P**rompt **O**ptimization), an innovative framework designed to significantly enhance the quality and usability of Text-to-Image (T2I) generative models. TIPO utilizes the Large Language Models (LLMs) to perform "Text Presampling" within the inference pipeline of text-to-image generative modeling. By refining and extending user input prompts, TIPO enables generative models to produce superior results with minimal user effort, making T2I systems more accessible and effective for a wider range of users.
## Usage
Use updated version of DTG extension (renamed to z-tipo-extension), current version of z-tipo-extension support stable-diffusion-webui, stable-diffusion-webui-forge and ComfyUI. SD-Next haven't been tested.

## Model arch and Training
This model is LLaMA arch with 200M parameters, the training data is combined version of Danbooru2023, Coyo-HD-11M. <br>
The total token seen is around 50B tokens. <br>
For more information please refer to the tech report and following table.
| | TIPO-200M | TIPO-200M-ft | TIPO-500M |
| ----------------- | ------------------------------------------------------------------------------ | ---------------------------------- | ------------------------------------------------------------------------------ |
| Arch | LLaMA | LLaMA | LLaMA |
| Max ctx length | 1024 | 1024 | 1024 |
| Batch Size | 2048 | 2048 | 3584 |
| Training dataset | Danbooru, GBC10M, 5epoch<br />Danbooru, GBC10M, Coyo11M, 3epoch | Danbooru(pixtral), Coyo11M, 2epoch | Danbooru, GBC10M, Coyo11M, 5epoch |
| Real Token Seen* | 40B token | 50B (10B more from TIPO-200M) | 30B token |
| Training Hardware | RTX 3090 x 4 | RTX 3090 x 4 | H100 x 8 |
| Training Time | 420 hour` | 120 hour` | 100 hour` |

*: We only count "non-padding token" in the token seen, since all the training data have very large length range. <br>
`: Since the training data is pretty short, it cost more time to reach same token seen than general LLM pretraining. <br>
As reference, with 4096 as max ctx length and almost all the data have reach that length, you may only need 2days to reach 10B token seen on RTX 3090 x 4 with 200M model.
### Evaluation
**Evaluation are done on TIPO-200M model** <br>
We have tested TIPO compared to other Model in several test and metrics:
#### Scenery tag test
In this test we use single "scenery" tag as input. (With some certain meta) <br>
To test each prompt gen method to see if they can obtain the desired distribution of outputs while maintain the quality of images.
| Scenery Tag Test | Original | GPT4o-mini | Prompt DB | Promptis | TIPO(ours) |

| AI Corrupt ↑ | 0.4257 | *0.7490* | 0.5024 | 0.5669 | **0.9195** |
#### Short/Truncated Long test
In this test we use short caption or manually truncated caption from GBC10M and CoyoHD11M. <br>
This test examine the ability of prompt gen method on handling almostly completed prompts.
