About
Llama 4 is Meta's latest open-weight large language model, built on a Mixture-of-Experts (MoE) architecture for improved efficiency. With a 128K token context window, Llama 4 offers strong performance across reasoning, coding, and multilingual tasks. As an open-weight model under a custom commercial license, it enables developers and enterprises to deploy, fine-tune, and customize the model for specific use cases. Early benchmarks show Llama 4 competitive with GPT-4o and Claude 3.5 Sonnet on several key metrics while being significantly more efficient to run.
