       | Maybe I'm being dumb but is this a generic chat UI for openai
       | models only? Pretty bearish on adoption of this if so. As a
       | pragmatic dev I'd definitely not be keen to bake model lock-in
       | into my UI for functionality as generic as chat.

       | This looks very similar to CopilotKit and AG-UI. With CopilotKit

       | 
       | With ChatKit you can proxy everything through your ChatKit API
       | "proxy" and implement the "agentic" stuff in the proxy.
       | 
       | Even the React APIs look very similar.
       | 
       | Looks like a vendor lock-in and a way to stop the AG-UI ecosystem

       | For a chat app UI?

       | So not so framework-agnostic, or am I missing something ?
