Unlocking ChatGPT's Secret Brain Slider

There is a hidden slider in ChatGPT that completely changes how hard the AI thinks before it answers you. If you are using the new o1 or o3-mini models, you have probably noticed they sometimes take forever to answer simple questions. Now, you can manually set their "Reasoning Effort" to Low, Medium, or High. Setting it to Low gives you lightning-fast answers, just like GPT-4o. But crank it up to High, and the AI unlocks its full brainpower to solve complex coding and math. To find it, just start a new chat, select an advanced model, and click the new "Reasoning" option next to its name. Stop letting the default "Auto" setting guess what you need. Take back control and make the AI work on your terms.
