What are the Copilot Chat (Copilot Basic) official limitations

The provided context does not list numeric or per‑user rate limits (such as maximum prompts per session, images per day, or documents per day) for Copilot Chat or Copilot Basic.

From the context, only these limitation-related points are explicitly documented:

1. Microsoft 365 Copilot Chat usage reporting
   • The Microsoft 365 Copilot Chat usage report shows:
     • Total active users
     • Average daily active users
     • Total prompts submitted
     • Average prompts submitted per user
   • These are analytics metrics for admins, not hard product limits.
2. Chat API limitations (for the Microsoft 365 Copilot Chat API, preview)
   • No action/content-generation skills (cannot create files, send emails, schedule meetings).
   • Only textual responses.
   • No tools such as code interpreter and graphic art.
   • No support for long-running tasks (risk of gateway timeouts).
   • Uses enterprise search and web search grounding by default; web search off is single-turn only.
   • Subject to semantic index limitations.
   • Returns AI-generated responses that may be inaccurate and must be verified.
3. Copilot Chat feature limits and controls (functional, not numeric quotas)
   • Features available include file upload, image generation, code interpreter, agents, etc., with:
     • “Standard access and file upload limits apply” for file upload.
     • “Standard access and image generation limits apply” for image generation.
   • Admins can manage Copilot Chat via the Copilot Control System, including:
     • Pinning Copilot Chat.
     • Allowing or blocking image generation.
     • Controlling agents.
     • Managing web search.
     • Removing access to Copilot Chat.
4. Teams-specific Copilot limitations
   • Copilot in Teams chats:
     • Can be added only to 1:1 or group chats (not self-chats or meeting chats).
     • Text-to-image generation in Teams chats is currently not supported (at the time of the referenced doc).

The context does not provide official numeric limits for:

• Number of prompts per session.
• Number of images per day per individual.
• Number of documents created per day per individual.

Only general statements such as “standard access and image generation limits apply” are present, without concrete values.
