Meta launches Llama 4, new AI models to challenge OpenAI and Google

Meta has released its newest collection of AI models, Llama 4, which now powers the company’s AI assistant across its platforms including WhatsApp, Messenger, and Instagram. The release includes two immediately available models—Scout and Maverick—with a third model, Behemoth, still in training.

Llama 4 Scout, designed to run on a single Nvidia H100 GPU, features a massive 10-million-token context window allowing it to process extremely lengthy documents. Meta claims Scout outperforms Google’s Gemma 3 and Gemini 2.0 Flash-Lite models, as well as the open-source Mistral 3.1 across various benchmarks.
