Meta releases its biggest ‘open’ AI model yet

Enterprise /

Meta’s latest open-source AI model is its biggest yet. Today, Meta said it is releasing Llama 3.1 405B, a model containing 405 billion parameters. Parameters roughly correspond to a model’s problem-solving skills, and models with more parameters generally perform better than those with fewer parameters. At 405 billion parameters, Llama 3.1 405B isn’t the absolute
