Meta Llama
Meta's open-source LLM powering a generation of AI products
Overview
Meta's Llama models (Llama 2, Llama 3, and beyond) have become the dominant open-source foundation for AI development. Unlike proprietary models, Llama weights are freely downloadable and can be run locally, fine-tuned on custom data, and integrated into commercial products. Llama 3 70B and 405B models compete with proprietary frontier models on many benchmarks. The ecosystem of Llama-based products — including Ollama, LM Studio, and Groq — makes running capable AI locally more accessible than ever.
What it does
Meta Llama is a base model that developers use to build applications, run locally, fine-tune for specific domains, and integrate via APIs. Consumer interfaces include Meta AI (built into WhatsApp, Instagram, and Facebook) and third-party tools like Ollama and LM Studio.
