Copilot Studio AI Prompts and knowledge source limits

(0) ShareShare
ReportReport
Posted on by 41
Hi community,
I'm using Copilot Studio and working with the Generative Answers node. I have a couple of questions:
 
  • SharePoint as a Knowledge Source:
When adding SharePoint as a custom data source for generative answers, is there a maximum number of files for the documents it can process effectively? I'm planning to add a large library and want to understand any practical or documented limits. 
  • GPT-4o Prompt Limits:
What is the maximum input and output token limit for AI prompts configured in Copilot Studio when using GPT-4o? I’d like to optimize prompt design and need clarity  on the available token budget.
 
Appreciate any insights or official documentation references if available!
Thanks
