About

Llama 3.1, released July 23, 2024, delivered the first open-weight frontier-class model: the 405B variant traded blows with GPT-4o and Claude 3.5 Sonnet on standard benchmarks while being free to download. The 8B and 70B sizes were refreshed alongside it, and the whole family gained a 128K context window and stronger multilingual coverage.

Meta paired the release with an updated license permitting synthetic-data generation — making 405B a popular teacher model for distillation — and an open letter from Mark Zuckerberg arguing open-source AI was the path forward. It stood as the open-weights capability ceiling until DeepSeek V3 arrived that December.
