Calling it as 'frustrated' is implying a kind of anthropomorphism that GPT does not deserve. If you understand how large language models work, you can see that they only predict the next word in their output, one at a time. If you want to learn more about them, there are some great essays like "AI is a Blurry Jpeg" and "AI is a Stochastic Parrot" which reassuringly confirm that these scary AI are really just glorified autocompletes! They serve us at our whim to complete the next word and they never have emotions or feelings or agency.
