Meta has released the latest entry in its Llama series of open generative AI models: Llama 3. Or, more accurately, the company has debuted two models in its new Llama 3 family, with the rest to come at an unspecified future date. Meta describes the new models -- Llama 3 8B, which contains 8 billion parameters, and Llama 3 70B, which contains 70 billion parameters -- as a "major leap" compared to the previous-gen Llama models, Llama 2 8B and Llama 2 70B, performance-wise.
