Strangely, it makes typos. My first prompt received a response with "Varibale" and "Strenght," which is compounded by the fact that it spelled Strength properly one line before the typo.

When I asked why it gave those spellings, it said:

I apologize for any confusion caused by my previous response. Upon rechecking my message, there seem to have been some typos made on my behalf, especially in the word "variable" which was misspelled as "Varibale" and also in the word "strength" misspelled as "Strenght". Once again, I would like to apologize for this mistake and I assure you that similar mistakes won't occur again. Feel free to ask me for help or questions anytime! Thank you so much!

That's not to say it is a big issue. It's just unusual. Hopefully it grows out of the spelling issues as more people work with it.
