Guide to Tool-Calling with Llama 3.1

Meta's Llama 3.1: A Deep Dive into Open-Source LLM Capabilities

Meta continues to lead the charge in open-source Large Language Models (LLMs). The Llama family, evolving from Llama to Llama 2, Llama 3, and now Llama 3.1, demonstrates a commitment to bridging the performance gap between open-source and closed-source models. Llama 3.1, particularly its 450B parameter variant, is a significant leap, achieving state-of-the-art (SOTA) results comparable to leading closed-source models. This article explores the capabilities of the smaller Llama 3.1 models, focusing on their impressive tool-calling functionality.

Introducing Llama 3.1:

Llama 3.1 comprises eight models: three base models (8B, 70B, and the groundbreaking 405B) and their corresponding instruction-tuned versions. Meta also introduced an enhanced Llama Guard (for detecting harmful outputs) and a Prompt Guard (a BERT-based model for identifying malicious prompts). Further details on Llama 3.1 are available [here](insert link if available).

Llama 3.1 vs. Llama 3:

Architecturally, Llama 3.1 and Llama 3 are identical. The key difference lies in the expanded training data (15 trillion tokens) and the resulting improvements. Llama 3.1 boasts a larger context window (128k tokens versus Llama 3's 8k) and enhanced multilingual capabilities. Critically, Llama 3.1 models were trained specifically for tool-calling, facilitating the creation of more sophisticated applications. The licensing has also been updated, allowing the use of Llama 3.1 outputs to improve other LLMs.

Performance Comparison: Llama 3.1 and SOTA Models:

Llama 3.1's 450B parameter model surpasses NVIDIA's Nemotron 4 340B Instruct model and rivals GPT-4 in various benchmarks (MMLU, MMLU PRO). While trailing GPT-4 Omni and Claude 3.5 Sonnet in certain areas (IFEval, coding), it excels in mathematical reasoning (GSM8K, ARC). Its competitive coding performance underscores the progress of open-source models.

Getting Started with Llama 3.1:

A Hugging Face account is required ([link]). Access to the gated repository necessitates accepting Meta's terms and conditions ([link]). An access token is needed for authentication ([link]).

Downloading Libraries:

!pip install -q -U transformers accelerate bitsandbytes huggingface

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("meta-llama/Meta-Llama-3.1-8B-Instruct", device_map="cuda")
model = AutoModelForCausalLM.from_pretrained("meta-llama/Meta-Llama-3.1-8B-Instruct", load_in_4bit=True, device_map="cuda")
