[OpenAI Updates ChatGPT Reasoning Control Feature, Adds Reasoning Intensity Slider for Plus/Pro Users] According to Deep Tide TechFlow, on August 7, OpenAI announced an update to ChatGPT's reasoning control feature. Plus and Pro users can now use a slider to adjust the reasoning intensity the model applies in a single response, enhancing flexibility in usage. Meanwhile, Free and Go users can now use the 'Think' button to enable the model to perform more reasoning on complex questions. Additionally, Plus and Pro users can now access the updated GPT-5.6 Sol version and the new slider feature within ChatGPT. OpenAI stated that this version is primarily designed for everyday conversations and is therefore only applicable to ChatGPT's chat scenarios; the GPT-5.6 Sol version for Work and Codex will remain unchanged in this update.
