Recent updates to account usage guidelines for Gemini 2.5 Pro have clarified restrictions on prompts and features. Users on a free account can now utilize up to five prompts per day. Those with an AI Pro plan are entitled to 100 prompts, while an AI Ultra plan allows for 500 prompts daily.
Additionally, free account holders are limited to five Deep Research reports and can generate up to 100 images daily. For those needing more than 100 AI-generated images in a single day, an upgrade to either the Pro or Ultra account is required, which provides the ability to create up to 1,000 images.
These changes aim to provide more transparency regarding account limitations, offering a clearer understanding of what users can expect in terms of usage. Further details about the plans can be accessed through the Gemini support page.
