Microsoft 365 Copilot Chat


Microsoft have launched a new addition to the Copilot family, confusingly called Microsoft 365 Copilot Chat.

Copilot Chat was already a thing (that is different to Copilot Biz Chat) and this seems to be a re-positioning as they add some new capabilities too. It is a basic, entry point tool that sits below Microsoft 365 Copilot.

Microsoft 365 Copilot Chat is free and has access to internet info to give “web-grounded” responses. Additionally it can interact with Agents (more on that later) and also has elements of the “Copilot Control System” to help with corporate data privacy.

The table below shows how it stacks up against the “full” Microsoft 365 Copilot product:

One of the new additions is that users of this free product can use 2 types of agents on a Pay As You Go (PAYG) basis, they are:

  • “Tenant Graph” grounded agents
  • Autonomous action agents

“Tenant Graph” grounded means agents that can access internal company data as well as internet information, giving answers with additional, organisation specific info and context. This is an additional PAYG per-message cost for M365 Copilot Chat users but is included within the M365 Copilot license – adding a new variable to consider when pricing up licensing options.

Autonomous actions are where the agent uses “generatively orchestrated triggers, topics, data connectors, and workflows” to act on behalf of a user. This is an additional PAYG per-message cost for all users – it is an additional cost even for users licensed with M365 Copilot.

For more info and details on the PAYG per-message pricing model – see my post here.
