BingGPT for Windows doesn[SQ]t exist as a standalone application or program you can download and install. There[SQ]s no official "BingGPT" app from Microsoft.

What you likely encountered are references to using the Bing Chat (powered by an improved version of the GPT model) *through* the Bing website or the Edge browser on Windows. These are the primary ways to access Bing Chat[SQ]s capabilities on a Windows computer. There[SQ]s no separate installable program called "BingGPT" for Windows.
