Researchers demonstrated that large language model (LLM) agents can extract identity clues from free‑text data, search the web autonomously, and match those clues to real‑world individuals. In experiments using interview transcripts, Reddit comments, and a large pool of Reddit users, the AI was able to correctly re‑identify a measurable share of participants while maintaining high precision. The findings highlight a growing capability of AI to breach pseudonymity, raising concerns about privacy in online platforms. Read more →

OpenAI CEO Sam Altman announced that the company will revise its contract with the U.S. Department of Defense to explicitly forbid the use of its artificial‑intelligence system for mass surveillance of Americans. In an internal memo shared on X, Altman detailed new language tying the restriction to the Fourth Amendment and other applicable laws, and said he would prefer jail over complying with an unlawful order.

Perplexity has rolled out an upgraded voice mode for its Comet browser, allowing desktop users to navigate the web entirely by speech. The feature, powered by OpenAI’s gpt-realtime-1.5 model, lets users open sites, scroll pages, and follow links without touching a keyboard or mouse. A simple keyboard shortcut activates the mode, and a similar experience is slated for iOS later this month. Perplexity emphasizes privacy by processing voice locally when possible and avoiding cloud storage of click histories. Future updates promise a learning assistant, password manager, and cross‑device sync. Read more →
