Open-source frontier models democratising access to cutting-edge AI capabilities.
About
Meta AI develops the Llama family of open-weight language models, providing competitive frontier-model performance under permissive licences. The Llama 4 generation introduced natively multimodal architecture and context windows reaching 10 million tokens in Scout. All Llama models are free to download, fine-tune, and deploy — eliminating API costs for teams with their own inference infrastructure.
Key highlights
Free open-weight models — no API costs, no usage restrictions for most use cases
Llama 4 Scout offers the largest context of any open model (10M tokens)
Natively multimodal MoE architecture in the Llama 4 generation
Supported by every major inference stack: Ollama, vLLM, llama.cpp, TGI
Available on Hugging Face, Meta AI website, and major cloud providers
Models
Context windows, pricing, capabilities, and API identifiers — everything you need to choose the right model for your workload.
2025
Meta's flagship open model. A 400B mixture-of-experts architecture with 17B active parameters per token. Competitive with GPT-4o on multimodal benchmarks — free to download and self-host.
meta-llama/Llama-4-Maverick-17B-128E-Instruct2025
The context champion of the Llama 4 family, supporting up to 10 million tokens — enough to fit entire codebases or document libraries in a single prompt.
meta-llama/Llama-4-Scout-17B-16E-Instruct2024
A proven workhorse with strong instruction following and coding capabilities. Supported by virtually every open-source inference platform: Ollama, vLLM, llama.cpp.
meta-llama/Meta-Llama-3.3-70B-Instruct2024
The largest publicly released dense language model. Used as a teacher model for distillation and as a quality benchmark for comparing smaller open models.
