Hello,
1 - Is there a character limit for the article that will serve as a reference?
the character limit is currently set to 12,000 characters per article to balance request speed, performance, and cost per chat.
2 - Is it possible to include files in the answers?
Image files are supported. For PDFs or other file types, they should work as long as they are provided via a link and referenced in the article.
3 - Is it possible to use Gemini Free?
The initial setup described in the documentation file is intended to use the free Gemini API, with the option to upgrade to a paid plan as needs grow.
Hope this helps
