Meta on Wednesday announced its first major model since CEO Mark Zuckerberg rebooted the company’s AI efforts last year under a new division called Meta Intelligence Labs.

Anthropic said Tuesday that it is sharing a preview version of its upcoming AI model as part of a new cybersecurity initiative with a coalition of tech companies to find and fix vulnerabilities in critical software infrastructure.
