Building on Llama 2, it introduces key features like an enhanced tokenizer and Grouped-Query Attention (GQA). This article highlights Llama 3’s innovations, explores their real-world applications, and offers a guide to integrating Llama 3 with Novita AI’s LLM API.

Exploring the Core Concepts of Llama 3 Paper

The Llama 3 paper introduces advanced large language models by Meta AI, enhancing natural language processing in various languages. It features innovations like an enhanced tokenizer, the GQA mechanism, expanded training datasets, advanced filtering techniques, and a commitment to responsible development. These advancements redefine AI capabilities and set new standards for large language model utilization.

An Introduction to Llama 3’s Advanced Models

Llama 3 is a suite of language models supporting multilinguality, coding, reasoning, and tool usage. The largest model is a dense Transformer with 405 billion parameters and a context window of up to 128K tokens. Llama 3 matches the quality of leading language models like GPT-4 across various tasks. Meta AI is releasing Llama 3 publicly, featuring pre-trained and post-trained versions of the 405 billion parameter model, along with the input and output safety model, Llama Guard 3.

Goals for Llama 3

Meta AI’s Llama 3 aims to create top open models to rival proprietary options. By incorporating developer input, Meta AI enhances Llama 3’s usability and advocates for responsible practices in large language models (LLMs). The early release of these text-based models encourages community involvement. Llama 3 will expand with multilingual and multimodal features, longer context support, and improved core capabilities like reasoning and coding.

Llama 2 VS Llama 3: Key Differences Explained

Llama 3 introduces a new tokenizer, increasing the vocabulary size from 32K tokens to 128,256. This enhances text encoding efficiency for multilingual capabilities. However, this expands the input and output embedding matrices, raising the parameter count from 7 billion in Llama 2 to 8 billion in Llama 3.

Additionally, the 8 billion version of the model now incorporates Grouped-Query Attention (GQA), an efficient representation designed to improve handling of longer contexts.

How to Build with Llama 3?

Meta AI’s vision is to empower developers to customize Llama 3 for relevant use cases, facilitating the adoption of best practices and enhancing the open ecosystem. This release includes new trust and safety tools, such as updated components with Llama Guard 2, Cybersec Eval 2, and the introduction of Code Shield — a guardrail for filtering insecure code generated by LLMs.

Llama 3 has been co-developed with torchtune, a new PyTorch-native library designed for easy authoring, fine-tuning, and experimenting with LLMs. Torchtune offers memory-efficient training recipes fully implemented in PyTorch and integrates with platforms like Hugging Face, Weights & Biases, and EleutherAI. It also supports Executorch for efficient inference on mobile and edge devices. For guidance on prompt engineering and using Llama 3 with LangChain, Meta AI provides a comprehensive getting started guide that covers everything from downloading Llama 3 to large-scale deployment in generative AI applications.

Deploying Llama 3 at Scale

Llama 3 is now available on major platforms, including cloud providers and model API providers. For examples of how to utilize all these features, please refer to Llama Recipes, which includes all of Meta AI’s open-source code.

Understanding the Llama Model Family

Llama (Large Language Model Meta AI, previously stylized as LLaMA) is a series of autoregressive large language models (LLMs) developed by Meta AI, with its initial release in February 2023. The most recent version is Llama 3.2, which was launched in September 2024.

What are the models in the Llama series?

Below are the Llama family models available in Novita AI. If you’re interested in any model, feel free to click and try it out directly.

Comparison of models

The training cost column reflects only the cost for the largest model. For instance, ‘21,000’ represents the training cost of Llama 2 69B, measured in petaFLOP-days. To clarify, 1 petaFLOP-day is equivalent to 1 petaFLOP/sec multiplied by 1 day, which equals 8.64E19 FLOP.

Achieving State-of-the-Art Performance with Llama 3

Meta AI’s new 8B and 70B parameter Llama 3 models represent a significant advancement over Llama 2, setting a new benchmark for LLMs at these scales. With enhancements in pretraining and post-training, the pretrained and instruction-fine-tuned models are now the leading options available today at the 8B and 70B parameter levels. Improvements in post-training procedures have significantly reduced false refusal rates, enhanced alignment, and increased diversity in model responses. Additionally, Llama 3 demonstrates greatly improved capabilities in reasoning, code generation, and instruction following, making it more steerable than ever.

In developing Llama 3, Meta AI focused on model performance on standard benchmarks while also optimizing for real-world applications. To achieve this, a new high-quality human evaluation set was created, comprising 1,800 prompts that address 12 key use cases: seeking advice, brainstorming, classification, closed question answering, coding, creative writing, extraction, embodying a character or persona, open question answering, reasoning, rewriting, and summarization. To avoid unintentional overfitting, even the modeling teams at Meta AI do not have access to this evaluation set. The chart below displays the aggregated results of human evaluations across these categories and prompts, comparing Llama 3 to Claude Sonnet, Mistral Medium, and GPT-3.5.

Preference rankings from human annotators, based on this evaluation set, demonstrate the superior performance of Meta AI’s 70B instruction-following model compared to similar-sized competing models in real-world scenarios.

Llama 3 paper highlights Meta’s advancements in large language models. Implementing these innovations effectively in real-world scenarios is crucial. The LLM API on Novita AI offers developers a streamlined interface to access and utilize these powerful models based on the insights from the Llama 3 paper.
