Anthropic sees growing potential for language models in cybersecurity. The company cites results from the CyberGym leaderboard: Claude Sonnet 4 uncovers new software vulnerabilities about 2 percent of the time, while Sonnet 4.5 increases that rate to 5 percent. In repeated tests, Sonnet 4.5 finds new vulnerabilities in more than a third of projects.
In a recent DARPA AI Cyber Challenge, Anthropic notes that teams used large language models like Claude "to build 'cyber reasoning systems' that examined millions of lines of code for vulnerabilities to patch." Anthropic calls this a possible "inflection point for AI’s impact on cybersecurity."
Meta is set to start mining users' conversations with its chatbot to target ads and content across all Meta platforms, including Facebook and Instagram. Beginning December 16, 2025, anything users say to Meta AI—by text or voice—will feed into the company's ad and content algorithms. If someone discusses hiking with the AI, for instance, they can expect to see more hiking-related ads, posts, and groups. Meta says it will exclude sensitive subjects like religion, health, and political views from this data collection.
Users can try to limit what shows up in their feeds using settings like "Ads Preferences," but these changes only apply if accounts are linked in the Accounts Center. Meta plans to alert affected users ahead of time by notification and email. The policy will take effect in most regions.
