- Open-Source Advantage: Unlike many of its competitors, Llama 3.1 is open-source, allowing for broader accessibility and potential improvements from the developer community.
- Performance Gains: Meta claims substantial performance enhancements over previous versions, bringing it closer to the capabilities of closed-source models.
- Focus on Safety: The model has been trained with a strong emphasis on safety, aiming to mitigate potential risks associated with AI.
- Potential for Innovation: By making the model accessible to a wider audience, Llama 3.1 could accelerate AI research and development, leading to breakthroughs in various fields.
What makes Meta’s latest offering so significant?
Meta has emphasized its commitment to open-source models, releasing everything from code to datasets.
Llama 3.1 is an unprecedented open-source language model boasting 405 billion parameters, nearly 2.5 times the size of GPT-3.5.
Alongside the flagship model, Meta also introduced two smaller variants, making Llama 3.1 one of the best multilingual and general-purpose LLMs available.
These models support native tool usage and feature an extensive context window. This article explores Llama 3.1 in detail and compares its performance to OpenAI’s latest GPT-4o mini.

Unboxing Llama 3.1 and Its Architecture
Meta’s new Llama 3.1 model has a staggering 405 billion parameters. According to Meta’s announcement, this model surpasses other LLMs in almost every benchmark.
It excels in general knowledge, steerability, mathematics, tool use, and multilingual translation. Llama 3.1 also supports synthetic data generation.
Meta has distilled this flagship model into two smaller variants: Llama 3.1 8B and 70B.

Training Methodology
All Llama 3.1 models are multilingual and feature a large context window of 128K tokens. These models are built for AI agents, supporting native tool use and function calling.
Llama 3.1 claims to be stronger in math, logic, and reasoning problems. It supports advanced use cases, including long-form text summarization, multilingual conversational agents, and coding assistants.
The models are also trained on images, audio, and video, making them multimodal. However, the multimodal variants are still under testing and have not been released as of July 24, 2024.
Comparison of the Llama 3 Family
Llama 3.1 is the first model in the Llama family with native support for tools, marking a shift towards Agentic AI systems. The development process includes two major stages:
Pre-training
Meta tokenizes a large, multilingual text corpus into discrete tokens and pre-trains the model on the resulting data.
This process involves performing next-token prediction, allowing the model to learn language structure and acquire vast amounts of world knowledge.
The pre-training stage involves processing 15.6 trillion tokens with an 8K token context window.
Meta then continues pre-training to increase the context window to 128K tokens.
Post-training
Post-training, also known as fine-tuning, aligns the model with human feedback. This stage includes supervised fine-tuning (SFT) on instruction tuning data and Direct Preference Optimization (DPO).
New capabilities like tool-use are integrated, and tasks such as coding and reasoning are enhanced. Safety mitigations are also incorporated at this stage.

Architecture Details
Llama 3.1 employs a standard, dense Transformer architecture. While its architecture is similar to Llama and Llama 2, Meta claims performance gains are primarily driven by improved training methods and optimizations.
Performance and Benchmarks
Meta claims that Llama 3.1 outperforms other LLMs in numerous benchmarks. Its superior capabilities in general knowledge, mathematical reasoning, and multilingual tasks set it apart. The model’s support for tool usage and its large context window are significant advantages.
Llama 3.1 vs. GPT-4o Mini
To assess Llama 3.1’s capabilities, it was tested against OpenAI’s GPT-4o mini. Llama 3.1’s performance in various benchmarks, including logic and reasoning problems, shows it as a formidable competitor.
The model’s native tool support and large context window offer significant benefits over GPT-4o mini.
Here’s a comparison of Llama 3.1 and GPT-4o Mini in tabular form:
