Models with thinking capabilities are available in Google AI Studio and through the Gemini API. Thinking is on by default in both the API and AI Studio because the 2.5 series models have the ability to automatically decide when and how much to think based on the prompt. For most use cases, it's beneficial to leave thinking on. But if you want to to turn thinking off, you can do so by setting the thinkingBudget parameter to 0.
