The thing you actually open is an app. An app may call on a model to process input, and combine functions like uploading, searching, and file generation. They work together, but have different responsibilities.
Two Layers in One Task
A model can write an explanatory outline based on teaching requirements. An app receives your request and files, and decides how to organize the input; if it has file tools, it can also generate downloadable materials.
The same model can appear in two apps, one of which can generate PPTX while the other only provides a text outline. This can happen. The same model doesn't mean the same tools and environment.
Look at Actual Features First, Don't Guess from Names
| What you want to confirm | What you can check |
|---|---|
| Whether it accepts image materials | Input support of the current app and the model it uses |
| Whether it actually generates files | Available tools and successful outputs |
| Whether it can inspect visuals | Ability to open or render images and perform inspection |
An interface labeled "AI Assistant" may also have multi-step execution capabilities; a name containing "Agent" doesn't guarantee support for all tasks.
Describe Results Accurately
You can say "this environment has generated an openable file" rather than just "this model can make any file." Accurately describe verified capabilities so that when you switch environments, you know what needs to be rechecked.
