Llama
Meta's open-source family of large language models you can download, customize, and run without API costs or vendor lock-in.
What is Llama?
Llama is Meta's family of open-source large language models that you can download and run yourself.
Unlike ChatGPT or Claude, Llama models come with open weights. You get the actual model files to host wherever you want, fine-tune for your specific use case, and deploy without ongoing API costs.
Most builders use Llama through Hugging Face or cloud providers like AWS. The latest version, Llama 4, includes models from 7B to 400B parameters with features like 10 million token context windows and native multimodal capabilities. It's become the most downloaded open-source AI model family with over 1 billion downloads since 2023.
Free to use under Meta's permissive license. You only pay for your own compute costs.
