# i3 Model - Ultra-Efficient Pretraining Language Model

## Model Description

The **i3 Model** is designed to optimize **pretraining efficiency** while retaining core language modeling capabilities.  
Its architecture allows training on **memory-constrained hardware**, including CPU-only setups, without sacrificing sequence modeling performance.  

> [!Note]  
> The i3 architecture is present within the model for highly efficient pretraining. It is designed to **reduce memory usage**, **speed up training**, and allow pretraining from scratch on tiny hardware. Internal details are abstracted for simplicity.

## Use

```python
from transformers import pipeline

pipe = pipeline("text-generation", model="FlameF0X/i3-12m")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)
````

## i3 Architecture (Abstract Overview)

### Design Philosophy

The i3 model targets **CPU-friendly, memory-constrained pretraining**, emphasizing:

* Long-range sequence modeling
* Low-rank weight updates for memory savings
* Efficient factorized attention
* 4-bit weights and microbatching for minimal memory footprint

## Technologies used in the i3 Architecture that are open-sourced by me:

* [Low-Rank Pre-training](https://github.com/FlameF0X/Low-Rank-Pretraining) - LoRa for pre-training.
