We have identified the underlying issue and are working to restore functionality.
Investigating
We have detected an issue where some users are encountering 400 errors when chatting with Agent Underlord. These errors appear to be intermittent and are occurring with multiple models selected. As a workaround, some users have reported success with clearing their cache and refreshing, please note however that this will start a new conversation/thread with Agent Underlord. We will update as soon as we have more information.
