Microsoft 365 Copilot is

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.
