Adding a feature because ChatGPT incorrectly thinks it exists (via) Adrian Holovaty describes how his SoundSlice service saw an uptick in users attempting to use their sheet music scanner to import ASCII-art guitar tab... because it turned out ChatGPT had hallucinated that as a feature SoundSlice supported and was telling users to go there!

So they built that feature. Easier than convincing OpenAI to somehow patch ChatGPT to stop it from hallucinating a feature that doesn't exist.

Adrian:

To my knowledge, this is the first case of a company developing a feature because ChatGPT is incorrectly telling people it exists. (Yay?)
