Facebook parent company Meta Platforms Inc. debuted a new and powerful AI model that Chief Executive Officer Mark Zuckerberg called “state of the art” and said will rival similar offerings from competitors like OpenAI and Alphabet Inc.’s Google.

The new model released Tuesday, called Llama 3.1, took several months to train and hundreds of millions of dollars of computing power. The company said it represents a major update from Llama 3, which came out in April.
