What does it mean when my prompt exceeds the context window?

You may get a message that you’ve exceeded the context window for uploading and analyzing files.

What Is a context window?

When you upload files to the Gemini web app, it needs to "read" the content to provide useful insights or answers. The context window is like the reading capacity. It determines how much content can be understood together at one time.

What does it mean when my prompt exceeds the context window?

A larger context window allows Gemini to read and comprehend more. If you exceed the context window, this could lead to responses that don’t take into account all the content provided or miss connections or details throughout the content. This is most relevant for prompts that require attention to many details scattered throughout large file(s).
