AI Daily Brief — 23 February 2025

Sunday delivered xAI’s voice-mode debut. Grok Voice early beta went live in the Grok iOS app for X Premium+ and SuperGrok subscribers — Ara (female) and Rex (male) voices, multiple personalities including Unhinged (yells, insults, screams), Romantic, Genius, Storyteller, Conspiracy, Unlicensed Therapist, and Grok Doc. Musk warned of expected issues; Riley Goodside’s viral demo of the Unhinged mode (Grok ends a call by shrieking and insulting the user) defined the launch reception. Android remained in pre-registration. DeepSeek’s Open Source Week warmup continued ahead of Monday’s FlashMLA drop. Frontier labs otherwise dark.
