Meta has released the latest entry in its Llama series of open source generative AI models: Llama 3. Or, more accurately, the company has open sourced 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. (Parameters essentially define the skill of an AI model on a problem, like analyzing and generating text; higher-parameter-count models are, generally speaking, more capable than lower-parameter-count models.) In fact, Meta says that, for their respective parameter counts, Llama 3 8B and Llama 3 70B — trained on two custom-built 24,000 GPU clusters — are are among the best-performing generative AI models available today.
