Meta launches Muse Voice Transcribe, a real-time multilingual speech-to-text model

Meta unveiled Muse Voice Transcribe, its first real-time audio perception model, capable of transcribing over 20 speakers simultaneously while switching between more than 20 validated languages, including mid-sentence code-switching.

Palo Alto Networks tops Q4 forecasts as AI-driven security demand grows

Palo Alto Networks reported fiscal fourth-quarter revenue of $3.41 billion and adjusted earnings of $1.02 per share, both above analyst expectations, with revenue up 34% year-over-year.

The model reportedly scored perfectly on ExploitBench and found two zero-day flaws in an internal test, prompting OpenAI to limit access to its most advanced capabilities and add extra monitoring before release.

Val Town's team found that most new Pro subscribers in July were referred by AI systems, chiefly Claude, even before the company deliberately optimized its site for machine readers. They discovered that many of these referrals came not from clickable citations but from the models' training memory mentioning Val Town as plain text, meaning standard referral tracking like utm_source and Referer headers missed much of the actual traffic source.
