# Cortex 2 chat preview
A small GPT model for conversational chat, trained completely from scratch (custom PyTorch architecture, no `transformers` library involved).
> ⚠️ **Note:** this is a **preview** release and may communicate worse than [Cortex 1 Chat](https://huggingface.co/VADRK155/Cortex-1-Chat).
- **Parameters**: 346m
- **Weights format**: fp16
- **Architecture**: Decoder-only Transformer (custom implementation)
- **Training**: from scratch, no pretrained weights used
> ⚠️ **Note:** the context window is only **256 tokens**, so the model will forget earlier parts of the conversation quickly.
## How to run
2. Install dependencies:
pip install -r requirements.txt
3. Run:
python chat.py
## Limitations
This is a small model, so it may lose coherence, mix up facts, or cut off mid-thought — expected behavior for this parameter count. |
