Meta's open model family — the most widely deployed LLMs in the world.
Llama is Meta's open-weight model family and the backbone of a huge share of self-hosted and open AI apps. In 2026 Llama 4 spans efficient edge models to frontier-class multimodal versions, with a community and tooling ecosystem no other open model can match.
Who it's for: Builders who want the largest open model ecosystem — startups, researchers, and enterprises avoiding lock-in.
The widest support across Ollama, vLLM, Hugging Face, and every framework.
Llama 4 handles images and long context across the family.
Tiny variants for devices, massive ones for data centers.
LoRA, full fine-tunes, and distillation are all well documented.
Llama remains the default open model in 2026 for one reason: ecosystem. If you are building on open weights, the tooling and community around Llama save you weeks. Run it locally with Ollama and you own your AI stack.
