Llama 3.1
The Llama 3.1 models are a collection of pretrained and instruction fine-tuned large language models (LLMs) in 8B, 70B, and 405B sizes that support a broad range of use cases. They are particularly suited for developers, researchers, and businesses to use for text summarization and classification, sentiment analysis, language translation, and code generation.
According to Meta, Llama 3.1 405B is one of the best and largest publicly available foundation models (FMs), setting a new standard for generative AI capabilities. It is particularly well suited for synthetic data generation and model distillation, which improves smaller Llama models in post-training. The models also provide state-of-the-art capabilities in general knowledge, math, tool use, and multilingual translation.
All of the new Llama 3.1 models demonstrate significant improvements over previous versions, thanks to vastly increased training data and scale. The models support a 128K context length, an increase of 120K tokens from Llama 3. This means 16 times the capacity of Llama 3 models and improved reasoning for multilingual dialogue use cases in eight languages: English, German, French, Italian, Portuguese, Hindi, Spanish, and Thai.
Llama 3.1 models in Amazon BedrockOther improvements include an enhanced grasp of linguistic nuances, meaning Llama 3.1 shows improved contextual understanding and can handle complexities more effectively. The models can also access more information from lengthy passages of text to make more informed decisions, as well as leverage richer contextual data to generate more subtle and refined responses.
"We have a longstanding relationship with Meta and are excited to make their most advanced models available to AWS customers today," said Matt Garman, CEO of AWS. "Customers love the ability to customize and optimize Llama models specific to their individual use cases, and with Llama 3.1 now available on AWS, customers have access to the latest state-of-the-art models for building AI applications responsibly.”
For the past decade, Meta has been focused on putting tools into the hands of developers, and fostering collaboration and advancements among developers, researchers, and organizations. Llama models are available in a range of parameter sizes, enabling developers to select the model that best fits their needs and inference budget. Llama models on AWS open up a world of possibilities because developers don’t need to worry about scalability or managing infrastructure. AWS offers a simple turnkey way to get started using Llama.
“Open source is the key to bringing the benefits of AI to everyone,” said Mark Zuckerberg, founder and CEO, Meta. “We've been working with AWS to integrate the entire Llama 3.1 collection of models into Amazon SageMaker JumpStart and Amazon Bedrock, so developers can use AWS's comprehensive capabilities to build awesome things like sophisticated agents that can tackle complex tasks.”
