🚀 Google launches Gemini 3 Flash frontier model 🚀
Cost-effective model outperforms 2.5 Pro while being 3x faster
Google expanded its Gemini family with Gemini 3 Flash - a new frontier model that outperforms 2.5 Pro on several major benchmarks while being 3x faster at a fraction of the cost. The model features stronger instruction following and better detail preservation. Flash powers both AI Mode in Google Search and can generate complete apps from prompts.

📱 ChatGPT app store has arrived 📱
Platform shift allows developers to publish tools directly inside ChatGPT
OpenAI has opened submissions for third-party apps inside ChatGPT, letting developers publish tools directly on the platform after review and approval. This replaces earlier invite-only experiments and signals a shift toward turning ChatGPT into a full app platform, not just a chatbot. Approved apps appear inside ChatGPT and can be used in conversations without downloads or extensions. Several apps already demonstrate the possibilities: Photoshop and Canva for design work, Apple Music for creating and saving playlists, Gmail for inbox summaries and drafted replies, and AllTrails for hiking advice based on a large trail database.

The system ranks #1 on Big Bench Audio with sub-1-second time-to-first-audio, delivering performance at $0.05 per minute - exactly half the cost of OpenAI's Realtime API. The release marks xAI's entry into the competitive voice AI infrastructure market, bringing Tesla's in-car voice technology to external developers.
