Capabilities of Llama 3

Meta developed its latest open AI model i.e. Llama 3 being on par with the best proprietary models available today and as per Meta, addressing developer feedback to increase the overall efficiency of Llama 3 while focusing on the responsible use and deployment of LLMs was imperative. Compared to its previous version Llama 2, Llama 3 Meta has better reasoning abilities, and code generation while also following human instructions effectively. It also outperforms other open models on benchmarks that measure language understanding and response (ARC, DROP and MMLU). All thanks to the revolutionary capabilities of Llama 3:

State-of-the-Art Performance

Meta has pushed the boundaries of what's possible with large language models at the 8 billion and 70 billion parametre scales. The new Llama 3 models leverage major advances in pretraining and instruction fine-tuning to establish new state-of-the-art performance levels. Extensive iterative fine-tuning has substantially improved capabilities like instruction following, reasoning, and code generation while reducing false refusal rates and increasing response diversity. Comprehensive human evaluations across 12 major use cases like question answering, creative writing, and coding show Llama 3 outperforming other leading models like Claude, Mistral, and GPT-3.5.

Optimised Model Architecture

While utilising a relatively standard decoder-only transformer architecture, Llama 3 incorporates several key optimisations. A vastly expanded 128K token vocabulary and improved tokenizer allow for much more efficient encoding of language. The adoption of grouped query attention (GQA) across both the 8B and 70B models enhances inference efficiency. The models were trained on extremely long sequences of up to 8,192 tokens to better handle document-level understanding.

Massive High-Quality Llama 3 Training Data

Data quality was a major focus for Llama 3, with the models pre-trained on over 15 trillion high-quality tokens from publicly available sources - seven times more than Llama 2. The Llama 3 training data incorporates four times more coding data to boost capabilities in that domain. Over 5% of the data covers 30+ languages beyond English to lay the groundwork for future multilingual models like Llama 3. Extensive filtering pipelines using techniques like heuristic filtering, NSFW detection, deduplication, and quality classifiers curated a final dataset optimally mixed across sources for strong all-around performance.

Responsible AI Approach

Meta has adopted a system-level approach that puts developers in control when using Llama 3 models responsibly. Iterative instruction fine-tuning combined with extensive red-teaming/adversarial testing efforts prioritised developing safe and robust models. New tools like Llama Guard 2 using the MLCommons taxonomy, CyberSecEval 2 for code security evaluation, and Code Shield for filtering insecure generated code further enable responsible deployment. An updated Responsible Use Guide provides a comprehensive framework for developers.

Optimised for Efficient Deployment

In addition to updating the models themselves, a major focus was optimising Llama 3 for efficient deployment at scale. An improved tokenizer boosts token efficiency by up to 15% compared to Llama 2. The inclusion of GQA allows the 8B model to maintain inference parity with the previous 7B model. Llama 3 models will be available across all major cloud providers, model hosts, and more. Extensive open-source code for tasks like fine-tuning, evaluation, and deployment is also there.

Llama 3 vs Other AI Models

To evaluate the real-world performance of Llama 3, Meta developed a comprehensive human evaluation set, comprising 1,800 prompts spanning 12 key use cases, including advice-giving, brainstorming, classification, question-answering, coding, creative writing, and more. This evaluation set was designed to prevent accidental overfitting of the models, with even Meta's modelling teams having no access to it.
