I’m trying to understand how this is used, my current selfhosted setup is quite simple:

frontend - backend - vllm

Using the openai compatible api vllm returns with tool calls that need to be handeled by the backend, an results are then send to the frontend by the backend, the frontend never communicates with vllm directly.

Form what i can gather AG-UI is a way for the frontend to directly communicate with in my case vllm in a secure way? letting the frontend handle the tool calls?

If you take the name literally, you get a misleading impression.

I would say if you take the name “fuck cars” literally you get a way different impression.

Unless op used grok to make this how is it “their” tool if you use an open source model?
