H2: Google Gemini Just Got Smarter – Here’s Everything New in September 2025 H3: Gemini 2.5 Deep Think Rolls Out to Google AI Ultra Subscribers Google has begun limited access to Gemini 2.5 Deep Think, the most advanced reasoning mode yet. According to the official release notes dated 1 August 2025, Deep Think can run multiple parallel “streams of thought,” making it ideal for scientific research, complex coding and strategic planning. Early testers report responses that are slower but far more detailed, with clearer step-by-step logic. Bullet benefits • Multimodal reasoning across text, images and code • Iterative brainstorming for product design and R&D • Output length boosted by the 1 million-token context window in Ultra H3: Search Your Chat History Instantly On 21 August 2025 Google switched on full-text chat search across web and mobile. Tap the new magnifying-glass icon inside the Gemini app, type any keyword and every matching conversation surfaces in seconds. Power users can finally pick up old threads without scrolling forever. H3: Temporary Chats Protect Privacy If you need a one-off brainstorming session that won’t be stored or used for training, hit “Temporary Chat.” The feature, launched 13 August, wipes the transcript when you close the window—useful for confidential client work or personal topics. H3: Free Year of Google AI Pro for Students Students (18+) in the US, Japan, Indonesia, Korea and Brazil can now claim 12 months of Google AI Pro at no cost.
