What is Meta Llama?
The most popular open-source LLM family for self-hosted AI deploymentsMeta Llama is the most widely adopted open-source large language model family, developed by Meta AI Research and released under a permissive community license that allows commercial use. Llama 3.1, available in 8B, 70B, and 405B parameter sizes, delivers performance competitive with leading proprietary models across reasoning, coding, math, and multilingual tasks. The 405B model in particular matches or exceeds GPT-4 on many benchmarks while being freely available for download and self-hosting. Llama models have become the foundation of the open-source AI ecosystem, with thousands of fine-tuned variants available on Hugging Face for specialized tasks including medical Q&A, legal analysis, code generation, and creative writing. The models can be run locally on consumer hardware using quantization techniques through tools like Ollama, llama.cpp, and vLLM, making powerful AI accessible without cloud API costs.
