LLaMA is a family of open-weight language models developed by Meta AI (formerly Facebook AI Research). It is designed to understand and generate human-like text by predicting the next word in a sequence, a foundational capability for natural language processing (NLP) tasks.
Why LLaMA Matters
LLaMA models are in the same category as OpenAI’s GPT and Google’s PaLM, but with a key difference: they are open-weight, meaning researchers and developers can download and run the models themselves. This has made LLaMA particularly influential in the open-source AI community.
Despite being smaller in terms of parameter count than some competing models, LLaMA is optimized for efficiency and strong performance, especially on academic and enterprise-grade hardware. LLaMA models can be fine-tuned or used as-is for a wide range of tasks, including:
- Text generation
- Language translation
- Summarization
- Question answering
- Code generation
As of early 2025, Meta has released multiple versions, including LLaMA 2, which includes models trained with reinforcement learning from human feedback (RLHF) and optimized for conversational use cases.
LLaMA is Meta’s answer to large-scale language modeling. It offers high-quality performance with an open development philosophy and plays a central role in the growing ecosystem of customizable, deployable AI tools.
