M365 Copilot Chat GCC Release

Microsoft Copilot Chat is now available in the GCC cloud and has been rolling out, with completion expected by the end of June 2025. This release provides Copilot Chat to all users without requiring an M365 Copilot Add-on license.

By default, web-grounding is turned off in GCC tenants. If web-grounding is enabled, users can use Copilot Chat with data from the Internet. The query leaves the GCC boundary, but all necessary internet data required by Copilot to provide a response is brought back and processed within the GCC compliance boundary. Therefore, the risk for organizations is minimal and comparable to users using a public Internet search engine to find answers. Additionally, organizations may benefit from increased security as all user interactions with Copilot Chat are discoverable and comply with Microsoft’s Enterprise Data Commitments.

If web-grounding remains disabled, users will still have access to a basic ChatGPT offering with Copilot Chat. Users can utilize files with Copilot Chat, but no additional Internet data will be available. Users are limited to a maximum file size of 512 MB per uploaded file and a maximum of three file uploads per day.

New M365 Copilot Tuning

Microsoft 365 Copilot Tuning is a new feature currently in preview. Microsoft 365 Copilot's large language model (LLM) is a general model used by all Microsoft 365 tenants. This LLM is not specific to any customer, and it is not a learning model. When users interact with Microsoft 365 Copilot, the general LLM along with Microsoft 365 data is used to generate responses. While this setup functions adequately, the responses are not entirely tailored to an organization's unique knowledge or approach.

With Microsoft 365 Copilot Tuning, users can now create fine-tuned models that perform domain-specific tasks related to their organization's knowledge. These models can be trained on a subset of data, such as authoritative documents in a library. Once created using domain-specific data from your tenant, these models can be utilized by a Copilot Studio agent. The tailored model remains within your tenant and does not revert to the generic Microsoft 365 Copilot LLM. Therefore, results provided by an agent leveraging a fine-tuned model created with your organization’s data will be more accurate and comprehensive. These models are low-code solutions that are straightforward to create using Copilot Studio.

These reports can help organizations identify areas for improvement, assess training needs, and determine if users are fully leveraging Copilot's capabilities.  There are Peer Benchmark, Usage Frequency, and Feature Level Usage Insights reports, plus solutions to help communicate and message with end users to drive more adoption.

Introducing SharePoint Agents

SharePoint Agents are a new solution currently rolling out.  SharePoint Agents are scoped agents aligned to a site and all the documents and content within it.  On every SharePoint site, you will see a copilot icon with a default agent that has been created.  Now you can leverage agents on targeted content.

It is also very simple to create additional agents that are scope to a site, library, folder or even relevant files.  Creation of agents is integrated in with the SharePoint Ribbons and menu system.

Once a SharePoint agent is created, these agents can be shared via email, Microsoft Teams or referenced through Microsoft 365 Copilot Chat.  

SharePoint Agents are licensed through the Microsoft 365 Copilot License without any additional charges.  Users who do not have a Microsoft 365 Copilot License can still create and use SharePoint agents if they have Copilot Studio capacity packs or pay-as-you-go meters enabled.
