Meta drops Llama 3.1 405B to challenge GPT-4o
Meta just dropped its open-source Llama 3.1 family, headlined by a massive 405B model that rivals GPT-4o and Claude 3.5 Sonnet across key benchmarks. The entire lineup supports a 128K context window, and Meta has updated its license so developers can finally use 405B outputs to distill smaller models.
