I have been with InterSystems for 22 years (including my year as an intern) and I am currently in charge of the Application Services team. Application Services is focused on creating and enhancing inhouse applications within InterSystems (both based on InterSystems IRIS as well as a select number of commercial platforms).
@diba, great question! Within InterSystems we are using SerenityGPT for RAG on top of internal knowledge sources. SerenityGPT stores embeddings in IRIS and uses IRIS Vector Search to find content used for RAG. Please see our GenAI session from Ready 2025 for more details on how we're partnering with SerenityGPT.
We have a SerenityGPT Tenant which consumes the InterSystems Change Control (ICC) training content, and makes it available for chat. CCR calls the API to have a turn by turn chat with this SerenityGPT tenant to get access to the ICC knowledge. In the future we plan to add ICC Online Course Transcripts, CCR FAQs and CCR Community content to this Tenant as well to broaden the knowledge available to the AI Assistant.

You can spin up a container sandbox for playing with via Try IRIS:
