Are there hidden tokens in the Gemini 2.5 Pro thinking outputs? All I can see in the thinking is high level plans and not actual details of the “thinking.” If you ask it to solve a complex algebra equation, it will not actually do any thinking inside the thinking tag at all. That seems strange and not discussed at all.

If I remember correctly, basically all 'closed' models don't output the raw chain of thought, but only a high-level summary, to avoid other companies using those to train/distill their own models.

As far as I know deepseek is one of the few where you have the full chain of thought. Openai/Anthropic/Google give you only a summary of the chain of thoughts.

That’s a good explanation for the behavior. It is sad that the natural direction of the competition drives the products to be less transparent. That is a win for open-weight models.

To add clarity, it's a win for open-weight models precisely because only their CoT can be analyzed by the user for task-specific alignment.
