The Gemini app’s context window is 32K tokens without a paid plan, 128K tokens on Google AI Plus, and 1 million tokens on Google AI Pro and Google AI Ultra, according to Google’s Gemini Apps limits help page.
As of November 9, 2026, Google says a 1 million token window lets Gemini understand up to 1,500 pages of text or 30,000 lines of code. The context window is separate from usage limits: AI Plus gets 2x the standard limits, AI Pro 4x, and AI Ultra 5x or 20x the AI Pro limits depending on the subscription. If a chat or upload exceeds the window, Google warns that replies may not take all of the content into account.
Developers using the Gemini API get a separate limit per model. Google’s model page lists Gemini 3.5 Flash with an input limit of 1,048,576 tokens and an output limit of 65,536 tokens. Moving from AI Pro to AI Ultra raises usage limits but not the app’s context window.
