Bug Report – Claude 4 Sonnet (Thinking) Repeats the Same Answer Twice

Hi, I’m using Claude 4 Sonnet (Thinking), and I noticed a strange issue.
When I ask a question, Claude gives a full answer but then it starts “Thinking...” again right after, and gives me the same answer a second time.
I’m not clicking anything, it just happens automatically. This repeats the whole reply and uses up more tokens.
It happens even when I just send one prompt, and it keeps happening every time.

This happens with most models when using Flow (Merlin's agent). It gives two responses and apparently consumes more credits. There should be an option to deactivate and activate the agent so we can use it only when we need it.

This has also happened with me alot. I just thought that it was a ui bug or an api bug but if it's eating up twice the credits then this need to be fixed as soon as possible.

This happens to me aswell with Claude, so its eating the usage TWICE as fast.

Ricz Sabido Thanks for writing this up. This happens to me with Gemini 2.5 Pro. Hopefully these duplications don't cost extra credits.
