Which AI model should I use?
DataSort runs on Google Gemini. Pick a model in the assistant, or leave it on Auto.
The short answer
Leave it on Auto. It picks a model for each job: the fast one for cleaning a large file, a stronger one for reports and requests with several steps. Choose a model yourself when you want a quicker answer (Fast) or a more thorough one (Smart or Deep). Every reply, change and report in DataSort shows the model that made it.
Auto
Chosen for each task
Best for: everyday use. You never have to think about which model is right.
Who gets it: everyone, on every plan.
Good to know: on the Free plan the assistant uses Gemini 3.5 Flash Lite, tuned with worked examples so it plans changes as reliably as the larger model. Paid plans get Gemini 3.8 Flash.
Fast
Gemini 3.5 Flash Lite
Best for: quick edits and questions: sort, filter, rename a column, count rows, remove empty rows.
Who gets it: everyone, on every plan.
Good to know: it is also the model that cleans your files, because it follows the cleaning rules exactly at high speed.
Classic
Gemini 3.6 Flash
Best for: steady, careful answers from the previous generation of Gemini Flash.
Who gets it: Mid, Pro and the Day Pass. Free accounts get 3 messages a day, shared with Smart.
Good to know: it costs the same as Smart, so most people choose Smart; Classic is there if you prefer how it answers.
Smart
Gemini 3.8 Flash
Best for: requests with several steps, questions that span sheets, and written reports.
Who gets it: Mid, Pro and the Day Pass. Free accounts get 3 messages a day, shared with Classic.
Good to know: this is the model Auto uses for the assistant on paid plans and for AI Insights.
Deep
Gemini 4 Argon
Best for: the hardest questions and the most thorough AI Insights reports.
Who gets it: Pro, for the assistant and AI Insights, up to 150 requests a month under fair use.
Good to know: it is the most capable and the most expensive model, so once the month's allowance is used, replies use Smart until the next month.
How your data is handled
Whichever model you choose, your request and the part of your sheet it needs are sent to Google Gemini only to answer that request. Figures in reports are measured by DataSort from your file, never invented by a model. See the Privacy Policy for the details.
