AI Overviews adopts Gemini 3, adds AI Mode

• AI Overviews has been upgraded to the Gemini 3 model.
• The product also introduces a new "AI Mode" option.
• The move is intended to improve accuracy and the quality of generated overviews.
• Users can expect better reliability and clearer summaries, though details and timelines remain limited.

What changed

AI Overviews now runs on the Gemini 3 model and includes a freshly named "AI Mode." The announcement points to a backend model swap plus an interface or feature toggle called AI Mode.

The short description says the upgrade should help AI Overviews "get it right more often," implying a focus on improved factuality and summary quality. No additional technical specifications or benchmarks were provided in the source.

Why this matters

Switching to a newer base model typically brings gains in language understanding, context retention, and generation quality. For a product whose purpose is to produce concise overviews, those improvements can mean fewer errors and clearer, more useful summaries for readers.

Adding an "AI Mode" suggests a configurable experience: users may be able to choose a setting optimized for accuracy, brevity, or another goal. Even without details, a named mode usually signals a product-level control that tailors outputs for specific use cases.

What we know and what we don’t

From the available information we know only three core facts: the model upgrade to Gemini 3, the introduction of AI Mode, and that the change aims to increase correctness. The source does not include performance metrics, rollout timing, pricing, or which users will see the change first.

Without official benchmarks or release notes, it’s not possible to quantify how much accuracy will improve or what trade-offs (latency, cost, hallucination rates) might accompany the upgrade. Users and reviewers will need to test outputs to confirm gains.

What to watch next

Look for follow-up details from the AI Overviews team—release notes, before/after examples, or third-party comparisons that show how Gemini 3 performs in this product. Also watch for documentation on what AI Mode actually does and whether it becomes the default option.

Until more specifics are published, the upgrade is best read as a positive signal: a model refresh plus a user-facing mode intended to make generated overviews more reliable. Expect deeper coverage once detailed information and benchmarks are released.
