Gemini API adds PPT, ODP and ODS input and multimodal function responses

The Gemini API now accepts PowerPoint 97-2003 (PPT), OpenDocument Presentation (ODP), and OpenDocument Spreadsheet (ODS) files as input, and adds page-image processing for Word 97-2003 (DOC) files. Function responses can now return audio, video, and Office and OpenDocument files, including Files API URIs.

Who is affected:

Developers sending documents to Gemini or building tools that return files to the model.

What to do:

Review the Office and OpenDocument file docs and multimodal function response docs before updating tools.
