It is the Chroma provider of the [AI Community Toolkit](https://github.com/CommunityToolkit/AI).
 
 They follow the form of the [Agent Framework .NET samples](https://github.com/microsoft/agent-framework/tree/main/dotnet/samples/02-agents). Chroma takes the place of the vector store that the original sample uses. Each sample also comes in a variant with models that run locally in Ollama.
