Introducing Llama 2: Meta's Open-Source Large Language Models
A Variety of Scales for Diverse Applications
Meta has unveiled Llama 2, a suite of pretrained and fine-tuned large language models (LLMs) with scales ranging from 7 billion to 70 billion parameters. These models are designed for a wide range of applications, including dialogue generation, question answering, and code generation.
Optimized for Dialogue
Meta has developed fine-tuned LLMs, known as Llama 2-Chat, specifically for dialogue use cases. These models have been optimized to excel in conversations and are capable of generating natural-language text that aligns with the context and tone of the conversation.
Benchmarking results indicate that Llama 2-Chat models outperform open-source chat models on the majority of tested benchmarks, demonstrating their superior performance in handling dialogue tasks.
Free and Accessible for All
To foster innovation and accessibility, Meta is releasing Llama 2 under a permissive community license. This means that researchers, creators, and businesses can freely use the models for both research and commercial purposes. Meta believes that a freely accessible large language model ecosystem benefits the entire research and technology community.
With Llama 2, Meta aims to unlock the full potential of large language models while encouraging responsible use and innovation within the community.
