User: what was my previous question?
Google: Your previous question was "cna uto nfeir waht tihs si msieplnig?". I was able to understand this through a combination of contextual understanding and sub-word tokenization, which allowed me to infer the intended meaning despite the numerous typos. The corrected question is: "Can you infer what this is misspelling?".
GPT-5 thinking doesn't struggle with this. And although I dislike adding AI generated output to a comment section I found the response to the follow-up question interesting.
q: c u i t m o t s? a: “Can you infer the meaning of this sentence?”
I couldn't read it
Same here, that's pretty amazing.
