The US Department of Justice (DoJ) reportedly wants the court to order Alphabet Inc. to sell off the browser to dismantle the monopoly Google has over the internet search market and related advertising. Google, meanwhile, said that if it is forced to sell Chrome, the move would harm its consumers and businesses. Photo by Eliot Blondet/ABACAPRESS.COM

Overview

  • Google confirmed DeepMind built the model and integrated it into the Gemini app and website for free and paid users worldwide.
  • All images created or edited in Gemini now carry a visible watermark and an invisible SynthID tag for provenance.
  • New capabilities include combining multiple photos, multi‑step edits that preserve scene context, and transferring styles or textures between objects.
  • The system was previously evaluated on LMArena as “Nano Banana,” where user comparisons favored it by Elo-style scoring.
  • Business Insider’s tests found notably strong small edits and detail preservation, though the model sometimes faltered when merging different faces; Adobe says it is surfacing the model in Firefly and Express as investors weigh AI’s impact on traditional tools.
