Gemini 3.5 Flash Is Live—and Already Free in Search and the Gemini App
Gemini 3.5 Flash is now powering Google’s main AI experiences, and you can use it free today without any special sign‑up. Google has swapped this new model into Google Search’s AI Mode and AI Overviews, as well as the standalone Gemini app, so if you’ve interacted with Gemini recently, you’ve almost certainly been using Gemini 3.5 Flash. Designed as a fast “Flash” model, Google says it’s four times quicker than other frontier models and outperforms the older Gemini 3.1 Pro in coding and multimodal benchmarks. For everyday users, that means snappier responses and better understanding of mixed input like text plus images or files. Developers can tap Gemini 3.5 Flash through Google’s AI subscriptions, but you don’t need a paid plan just to chat with it, ask questions, or use it as your default assistant inside Search and the Gemini mobile app.
Google I/O’s AI Lineup: What’s Really Free Versus Subscription-Only
This year’s Google I/O leaned heavily into AI, but only a slice of what was announced is actually free today. The big caveat: some of the most powerful additions, like the new Omni model and many advanced Workspace features, sit behind paid AI subscriptions. If you want to experiment directly with Omni itself right now, you’ll need one of those subscriptions. The same goes for upcoming “information agents” in Search, which will initially be limited to Google AI Pro and Ultra subscribers when they launch. On the free side, though, Google has opened up Gemini 3.5 Flash in Search and the Gemini app, and is rolling out more no‑cost tools over the coming months. Think of it as a split strategy: power users and enterprises get premium agents and models, while mainstream users get a streamlined, but still capable, Gemini experience woven into familiar services.
Using the New AI Experiences in Google Search at No Cost
You can try several of Google’s new AI search features immediately without paying. First, switch to AI Mode in the Search box when it appears for you. Behind the scenes, this is now driven by Gemini 3.5 Flash, which powers richer AI Overviews and interactive responses. A new “Intelligent Search” box is rolling out as well: when you start typing a conversational query—like exploring a new hobby—it suggests more specific, AI‑generated follow‑ups you might not have thought of. These suggestions are multimodal, so you can also attach images, documents, videos, or even open Chrome tabs to refine what you’re asking. Another tweak makes AI Mode easier to access from results pages: when an AI Overview appears, you can expand it to reveal a chat box and seamlessly continue the conversation. All of this uses Gemini 3.5 Flash and is available to regular Search users for free as the rollout progresses.
Free AI Features Coming Soon: Agents, Universal Cart, and Interactive Demos
Beyond what’s live now, Google has promised more free AI features arriving in the coming months. One highlight is Universal Cart, which will let you add products from multiple stores into a single shopping cart directly from Search. Google says Universal Cart will be available to everyone when it launches, not just paying subscribers. Both free and paid users will also get access to certain agents that can handle bookings, such as restaurant reservations or private karaoke rooms, all within Search. Perhaps the most intriguing free upgrade is “agentic coding” powered by Gemini 3.5 Flash. When you search for complex topics—say, astrophysics—Google will be able to generate interactive elements or small demos in real time to help you explore concepts more intuitively. These features aren’t live yet, but they’re planned to roll out this summer as part of Google’s no‑cost AI offering.
Gemini App Refresh: A New Look on Top of a Freeer, Faster Model
If you prefer a dedicated AI assistant, the Gemini app now combines a fresh interface with the upgraded Gemini 3.5 Flash model under the hood, all still available for free use. Google has redesigned the app with what it calls a “Neural Expressive” aesthetic, adding new animations, bolder colors, updated typography, and refined haptic feedback. The visual overhaul is meant to feel more dynamic and conversational than the original Gemini design or Google’s usual minimalist look. Functionally, nothing extra is locked behind a paywall just to start chatting, brainstorming, or asking questions. As long as you’re signed into your Google account, you can make use of Gemini 3.5 Flash’s faster, more capable responses in the app today. Paid AI subscriptions remain optional for advanced workloads, while the standard Gemini experience stays a zero‑cost way to get hands‑on with Google’s latest model.
