Tess, short for Tesoro (Treasure in Italian), is a general purpose Large Language Model series created by Migel Tissera.

The compute for this model was generously sponsored by KindoAI.

Sample Inference Python Script:

python

import torch, json
from transformers import AutoModelForCausalLM, AutoTokenizer

model_path = "migtissera/Tess-3-Llama-3.1-70B"

model = AutoModelForCausalLM.from_pretrained(
    model_path,

    device_map="auto",
    load_in_4bit=True,
    trust_remote_code=False,
)

tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=False)

terminators = [
    tokenizer.convert_tokens_to_ids("<|end_of_text|>"),
    tokenizer.convert_tokens_to_ids("<|eot_id|>"),
]

    tokens = tokenizer.encode(instruction)
    tokens = torch.LongTensor(tokens).unsqueeze(0)
