Earlier quoted context omitted.
Gemini was good when the thinking tokens were shown to the user. As soon as Google replaced those with some thought summary, I stopped finding it as useful. Previously, the thoughts were so organized that I would often read those instead of the final answer.
In the API, the thinking tokens are just a different stream. You can still read them.
