Is it possible to run a multi-agent workflow with AG-UI?

[zzzzbb (easontsai)]

I have successfully followed the official documentation to expose a single agent via the AG-UI FastAPI endpoint.

Is it possible to use a workflow or an orchestrator (e.g., a sequential, group chat) with AG-UI?

Thanks!

Right now, you could turn a workflow into an agent with .as_agent() so it can be used within AG-UI. We haven't added support to add native workflows (yet).

zzzzbb (@easontsai) support for MAF Python Workflows in AG-UI will be added via #3911. FYI.

will this be added to .NET too? :)
This is great IMHO!
FYI in .NET I tried a workflow made of code custom executors which run agents (more control and determinism) and tried that .AsAgent() and it did not work well..
There are quite some issues identified on its .NET version...

One thing I’ve found useful with multi-agent workflows is keeping the UI protocol separate from the orchestration model.

The workflow should own coordination and participant transitions, while AG-UI should ideally just expose the resulting events consistently to the client.

This becomes especially noticeable once you introduce dynamic orchestration or remote agents, because you don’t want UI concerns influencing how the agents themselves coordinate.

I’ve been experimenting with multi-agent orchestration and A2A patterns in .NET here:

I’m also interested in how others are handling event correlation when multiple agents are producing streamed output in the same workflow.
