Meta released Llama 4 under an open-source licence in June 2026, marking a major upgrade to its popular Llama model family. Llama 4 Scout (17B active parameters) and Llama 4 Maverick (17B MoE) are available on Hugging Face and Meta's official repository. For the first time in the Llama series, both models support native vision inputs — allowing developers to build multimodal applications without separate image encoders. The 128K context window matches several commercial models. Llama 4 outperforms the previous Llama 3.3 70B on coding and reasoning benchmarks, and early tests show competitive performance against Claude 3.5 Sonnet on document analysis tasks.
