Microsoft 365 Copilot is
powered by what we call
the “Copilot System”,
a sophisticated processing
and orchestration engine.
It harnesses the power of
three foundational technologies:
The Microsoft 365 apps,
that's Word, Excel, PowerPoint,
Outlook, Teams, and more.
The Microsoft Graph,
that's all your content
and context, your emails, files,
meetings, chats, and calendar.
And a Large Language Model,
or LLM, a creative engine
capable of parsing and producing
human-readable text.
All accessible
through natural language.
It starts with a prompt
from you in an app.
Copilot pre-processes the prompt
through an approach
called “grounding”.
Put simply, grounding improves
the quality of the prompt,
so you get answers that
are relevant and actionable.
One of the most important
parts of grounding
is making a call to the
Microsoft Graph to retrieve your
business content and context.
Copilot combines
this user data from the graph
with other inputs
to improve the prompt.
It then sends
that modified prompt to the LLM.
You may be familiar
with what an LLM can do
based on your experience
with ChatGPT or Bing Chat.
Copilot takes the response
from the LLM
and post-processes it.
This post-processing
includes additional
grounding calls to the graph,
responsible AI checks,
security, compliance,
and privacy reviews
and command generation.
Finally, Copilot
sends a response to the user
and commands back to the apps.
Copilot iteratively processes
and orchestrates
these sophisticated services
to produce a result
that feels like magic.
