Llama
Meta's powerful open-source LLM. Run locally, fine-tune, and deploy commercially with no licensing fees.
What is Llama?
Meta's Open-Source Large Language Model
Llama is Meta's family of open-source large language models, released for both research and commercial use. Since the release of Llama 2 in 2023 and Llama 3 in 2024, it has become the dominant open-source foundation model, powering countless applications, fine-tunes, and research projects worldwide.
Why Llama Matters
Before Llama, powerful LLMs were locked behind proprietary APIs. Meta's decision to release model weights freely transformed the AI landscape, enabling a massive ecosystem of derivative models, specialized fine-tunes, and new research that would not have been possible with closed models.
- Available in 8B, 70B, and 405B parameter sizes
- Commercial use permitted under the Llama license
- Runs on consumer hardware at smaller sizes via quantization
- Supported by every major inference platform and framework
Key Features
Model weights are freely downloadable for research and commercial use, enabling full transparency and customization.
Available from 8B to 405B parameters, letting you choose the right balance of capability and compute cost.
The open weights make Llama the most popular base model for domain-specific and task-specific fine-tuning.
Llama 3 supports multiple languages and shows strong performance across diverse language tasks.
Every major framework (Transformers, Ollama, llama.cpp, vLLM) and every cloud platform supports Llama natively.
Who Uses Llama?
Companies deploy Llama on their own infrastructure to maintain data privacy and avoid per-token API costs.
Open weights enable mechanistic interpretability research, alignment studies, and novel architecture experiments.
Fine-tune Llama on domain-specific data to create medical, legal, coding, or industry-specific AI assistants.
Run Llama 8B on a laptop or gaming PC for fully private, offline AI capabilities.
