Microsoft's latest AI feature may just stop working. Here's why

Microsoft is indeed making access to OpenAI's 01 AI reasoning model completely free -- but there's a limitation and one which Microsoft is refusing to tell you about. Microsoft said Wednesday that it would provide access to OpenAI's o1 model, for free, to Copilot users as part of a toggle option called "Think Deeper." OpenAI uses the o1 model in its paid ChatGPT plans and charges 20/mo for "limited" access to the model, and unlimited access to it for a Pro plan costing 200/mo. However, Mustafa Suleyman, the chief of Microsoft's AI, said that the model would be "free and available," and "everywhere at no cost" -- potentially an enormous discount. Microsoft said Friday that there are limits to their new Think Deeper feature, which they're keeping mum about.
