Does the Gemini 2.5 Flash API have a 'thinking mode'?

Hello developer,

When I was using the Gemini 2.5 Flash web version, I noticed that I could choose whether to enable a ‘thinking mode’.

My question is: for the Gemini 2.5 Flash API, is there a ‘thinking mode’ that needs to be explicitly enabled, or does the API inherently (or by default/automatically) operate with this ‘thinking mode’ active?

Hey @One_people , To get summaries of the model’s reasoning process, set includeThoughts to true in your request. See the documentation for details.

It is enabled by default for 2.5 Flash models, even in the API.
As the top reply already stated, you can check out the reasoning of the model in the API, just like in AI studio.

Hello, when calling gemini-2.5-flash-preview-05-20, does it perform network searches by default? And, when using Python to call gemini-2.5-flash-preview-05-20, can I configure whether or not it performs network searches?

Could you clarify if my understanding is correct? Do you mean Google Search? If yes, then you can configure Google Search as a tool.
Please refer to the doc.

Thanks.
