Uploaded model

• Developed by: tomasonjo
• License: apache-2.0
• Finetuned from model : unsloth/llama-3-8b-Instruct

This llama model was trained 2x faster with Unsloth and Huggingface's TRL library.

For more information visit this link

Example usage:

Install dependencies. Check Unsloth documentation for specific installation for other environments.

%%capture
# Installs Unsloth, Xformers (Flash Attention) and all other packages!
!pip install "unsloth[colab-new] @ git+https://github.com/unslothai/unsloth.git"
!pip install --no-deps "xformers<0.0.26" trl peft accelerate bitsandbytes

Then you can load the model and use it as inference

from unsloth.chat_templates import get_chat_template

tokenizer = get_chat_template(
    tokenizer,
    chat_template = "llama-3", 
    map_eos_token = True, 
)

FastLanguageModel.for_inference(model) # Enable native 2x faster inference
