Meta Llama

Meta's Llama family of open-weight large language models provides state-of-the-art performance across reasoning, coding, and knowledge tasks in a freely available model family that can be downloaded, fine-tuned, and deployed without API costs or data privacy concerns. Llama models ranging from 8B to 405B parameters deliver performance competitive with proprietary models while enabling complete customization and on-premises deployment. Researchers, enterprises with data privacy requirements, and developers who want to fine-tune or self-host LLMs use Meta Llama as the foundation model for custom AI applications where control over model behavior, deployment infrastructure, and data handling is essential.
