Meta released Llama 4, the latest version of its open-source large language model family, for free download under a commercial licence — a direct challenge to the closed, subscription-based AI ecosystems of OpenAI, Google and Anthropic.

Llama 4 is available in three sizes — 8B, 70B and 405B parameters — with the largest version matching or exceeding GPT-4o performance on eight of twelve standard benchmarks. The model supports 32 languages and a 128,000-token context window.
