Llama 3.1 vs Llama 3: Which is Better?

Introduction

On July 23rd, 2024, Meta released its latest flagship model, Llama 3.1 405B, along with smaller variants: Llama 3.1 70B and Llama 3.1 8B. This release came just three months after the introduction of Llama 3. While Llama 3.1 405B outperforms GPT-4 and Claude 3 Opus in most benchmarks, making it the most powerful open-source model available, it may not be the optimal choice for many real-world applications due to its slow generation time and high Time to First Token (TTFT).

For developers looking to integrate these models into production or self-host them, Llama 3.1 70B emerges as a more practical alternative. But how does it compare to its predecessor, Llama 3 70B? Is it worth upgrading if you’re already using Llama 3 70B in production?

In this blog post, we’ll conduct a detailed comparison between Llama 3.1 70B and Llama 3 70B, examining their performance, efficiency, and suitability for various use cases. Our goal is to help you make an informed decision about which model best fits your needs.
