## Goals of Meta Llama3
Meta AI developers embarked on the development of Llama 3 with the aim of creating top-tier open models comparable to the best proprietary ones currently available. Their focus has been on incorporating developer feedback to enhance the overall utility of Llama 3, all while maintaining a leading role in promoting the responsible use and deployment of large language models. Following the open source ethos, they are committed to frequent releases, allowing the community to access these models during their developmental stages. The text-based models unveiled today represent the initial offerings in the Llama 3 lineup. Looking ahead, their objective is to expand Llama 3 to support multiple languages and modalities, extend context capabilities, and continually enhance performance across essential LLM functions like reasoning and coding.

## Key Features That Set Llama 3 Apart
Llama 3 possesses several key features that set it apart from other language models in the market

**Model architecture**
In accordance with their design philosophy, a relatively standard decoder-only transformer architecture was chosen for Llama 3. Several key enhancements were implemented compared to Llama 2. Llama 3 utilizes a tokenizer with a vocabulary of 128K tokens, resulting in more efficient language encoding and significantly improved model performance. To enhance the inference efficiency of Llama 3 models, grouped query attention (GQA) was adopted across both the 8B and 70B sizes. Models were trained on sequences of 8,192 tokens, with masking applied to ensure self-attention does not extend beyond document boundaries.

**Training Data**
Regarding training data, the team recognized the importance of a large, high-quality dataset. Consequently, substantial investment was made in pretraining data curation. Llama 3 is pretrained on over 15 trillion tokens sourced from publicly available data, seven times larger than the dataset used for Llama 2, and includes four times more code. In preparation for multilingual applications, over 5% of the pretraining dataset consists of high-quality non-English data spanning more than 30 languages.

To maintain data quality, a series of data-filtering pipelines were developed, incorporating heuristic filters, NSFW filters, semantic deduplication methods, and text classifiers. 
Interestingly, previous iterations of Llama proved effective in identifying high-quality data, with Llama 2 utilized to generate training data for text-quality classifiers powering Llama 3.

Extensive experimentation was conducted to optimize data mixing from various sources for the final pretraining dataset, ensuring robust performance across diverse use cases such as trivia questions, STEM, coding, and historical knowledge.

**Scale up**
To effectively harness the pretraining data for Llama 3 models, significant efforts were directed towards scaling up the pretraining process. A comprehensive set of scaling laws was meticulously developed to guide downstream benchmark evaluations. These laws empowered the team to select an optimal data mix and make well-informed decisions regarding the utilization of training compute resources. Notably, the scaling laws enabled the prediction of the performance of the largest models on key tasks, such as code generation, before the actual training commenced. This proactive approach ensured robust performance across various use cases and capabilities.

Throughout the development of Llama 3, novel observations regarding scaling behavior were made. For instance, while the optimal amount of training compute for an 8B parameter model corresponds to approximately 200B tokens, it was discovered that model performance continued to improve even after training on significantly larger datasets. Both the 8B and 70B parameter models exhibited log-linear improvements even after being trained on up to 15 trillion tokens. Although larger models can match the performance of smaller ones with less training compute, smaller models are generally preferred due to their increased efficiency during inference.

To train the largest Llama 3 models, a combination of three parallelization techniques was employed: data parallelization, model parallelization, and pipeline parallelization. This approach achieved a remarkable compute utilization of over 400 TFLOPS per GPU when trained on 16K GPUs simultaneously. Training runs were conducted on two custom-built 24K GPU clusters. To maximize GPU uptime, an advanced training stack was developed to automate error detection, handling, and maintenance tasks. Additionally, significant improvements were made to hardware reliability and detection mechanisms for silent data corruption, and scalable storage systems were developed to reduce the overheads of checkpointing and rollback. These collective enhancements resulted in an overall effective training time of over 95%. In summary, these improvements boosted the efficiency of Llama 3 training by approximately threefold compared to Llama 2.

**Fine-Tuned**
To fully unleash the potential of their pretrained models in chat use cases, they pioneered a novel approach to instruction-tuning. Their post-training methodology combines supervised fine-tuning (SFT), rejection sampling, proximal policy optimization (PPO), and direct preference optimization (DPO). The quality of prompts used in SFT and the preference rankings utilized in PPO and DPO significantly influence the performance of aligned models. Substantial improvements in model quality were achieved through meticulous curation of data prompts and multiple rounds of quality assurance on annotations provided by human annotators.

Leveraging preference rankings via PPO and DPO notably enhanced Llama 3's performance on reasoning and coding tasks. They discovered that when a model encounters a reasoning question it struggles to answer, it sometimes produces the correct reasoning trace; the model knows how to generate the correct answer but lacks the ability to select it. Training on preference rankings allows the model to learn this selection process.

## Benchmarks: Llama 3 vs Other Models
The introduction of the new 8B and 70B parameter Llama 3 models represents a significant advancement over Llama 2, setting a new benchmark for large language models at these scales. Through enhancements in both pretraining and post-training methodologies, the pretrained and instruction-fine-tuned models now stand as the leading options in their respective parameter ranges. Refinements in post-training processes have notably diminished false refusal rates, enhanced alignment, and diversified model responses. Moreover, substantial improvements have been observed in critical capabilities such as reasoning, code generation, and instruction comprehension, rendering Llama 3 more adaptable and responsive.

In the development of Llama 3, the team focused on assessing model performance on standard benchmarks while also prioritizing optimization for real-world scenarios. To achieve this objective, they created a new high-quality human evaluation set comprising 1,800 prompts covering 12 key use cases, including asking for advice, brainstorming, classification, closed question answering, coding, creative writing, extraction, inhabiting a character/persona, open question answering, reasoning, rewriting, and summarization. To prevent accidental overfitting of their models on this evaluation set, even their own modeling teams do not have access to it. The aggregated results of human evaluations across these categories and prompts, comparing Llama 3 against Claude Sonnet, Mistral Medium, and GPT-3.5, are presented in the chart below.

Preference rankings by human annotators based on this evaluation set underscore the robust performance of their 70B instruction-following model when compared to competing models of similar scale in real-world scenarios.

Their pretrained model further solidifies a new state-of-the-art standard for LLM models at those scales.
