Exclude thinking data from GenAI widget

Hello,

I have noticed that there is seemingly no option to prevent thinking/reasoning data from streaming into a Pega GenAI agent widget (Pega 25.1.2 version).

Scenario: I use Claude Sonnet 4.6, but I don’t want the agent widget to display thinking data to the user; only the actual response shall be shown.

Based on my understanding, the model endpoints themselves offer a clear separation into text and thinking blocks, so something like this should be possible.

Is there any way to achieve this programmatically at the moment in Pega 25.1.2 (you can, of course, instruct the agent to exclude this data from its response via a prompt, but that is unreliable and not a good way to do this, I’d say)?

Your help is much appreciated, thank you!

Hello Franz I think default SSE protocol is used to stream the agent output in case of conversational widget. Worth sharing this as a feedback request to the platform.
