Tess, short for Tesoro (Treasure in Italian), is a general purpose Large Language Model series created by [Migel Tissera](https://x.com/migtissera).
The compute for this model was generously sponsored by [KindoAI](https://kindo.ai).
# Sample Inference Python Script:
```python
import torch, json
from transformers import AutoModelForCausalLM, AutoTokenizer
model_path = "migtissera/Tess-3-Llama-3.1-405B"
model = AutoModelForCausalLM.from_pretrained(
model_path,

load_in_4bit=True,
trust_remote_code=False,
