Llama 3.1: Meta claims its new open-source AI outperforms GPT, Claude, other ‘closed’ rivals

On Tuesday Meta announced the launch of its latest and largest artificial intelligence (AI) model in a blog post. The company claimed that the new open-source model can outperform major closed AI models such as GPT-4, GPT-4o, and Claude 3.5 Sonnet across several benchmarks.

The new model is called Meta Llama 3.1 405B. The newer versions were filtered from the 405B model and now offer a 1,28,000 tokens context window. Meta claims both of these models are now the leading open-source large language models (LLMs) for their sizes.
