Tess-2.0-Llama-3-70B

Tess, short for Tesoro (Treasure in Italian), is a general purpose Large Language Model series. Tess-2.0-Llama-3-70B was trained on the meta-llama/Meta-Llama-3-70B base.

Compute for Tess-2.0-Llama-3-70B was sponsored by KindoAI.

Prompt Format

Prompt format used for this fine-tune is Llama-3

<|begin_of_text|><|start_header_id|>system<|end_header_id|>

You are a helpful assistant.<|eot_id|><|start_header_id|>user<|end_header_id|>

Who are you?<|eot_id|><|start_header_id|>assistant<|end_header_id|>

I am an AI<|eot_id|><|start_header_id|>user<|end_header_id|>

What's your name?<|eot_id|><|start_header_id|>assistant<|end_header_id|>

Training Methodology

Tess-2.0-Llama-3 was trained on the (still curating) Tess-2.0 dataset. Tess-2.0 dataset and the training methodology follows LIMA (Less-Is-More) principles, and contains ~100K high-quality code and general training samples. The dataset is highly uncensored, hence the model will almost always follow instructions.

The model was only fine-tuned for 2-epochs with a low learning rate to try and preserve its entropy as much as possible.

Sample code to run inference

python

Limitations & Biases:

While this model aims for accuracy, it can occasionally produce inaccurate or misleading results.

Despite diligent efforts in refining the pretraining data, there remains a possibility for the generation of inappropriate, biased, or offensive content.

Exercise caution and cross-check information when necessary. This is an uncensored model.
