OpenAI Kills Sora, Brett Adcock’s $100M AI Device Startup, Apple’s Siri Overhaul

Today we’re covering the biggest AI stories of March 25th, 2026. OpenAI officially shut down Sora, its AI video generator, freeing up compute for its next major model called Spud — with employees reportedly calling Sora a drag on resources and the move putting its $1 billion Disney partnership on ice. Figure AI founder Brett Adcock emerged from stealth with Hark, a new AI device startup he personally funded with $100 million, aiming to build the most advanced personal AI ever with a team pulled from Apple, Google, Meta, and Tesla. Plus, Apple is reportedly testing a standalone Siri app and a new chatbot experience called “Ask Siri” set to debut at WWDC in June — likely its last shot at defining Siri before users default to Claude or ChatGPT for everything.
