I have a theory that it should have a very different “personality” (probably more like writing style) depending on language because it’s an entirely different set of training data
In English chatGPT is rather academic and has a recognisable style of writing, if you’ve used it a bit you can usually get hints something was written by it just by reading it.
Does it speak in a similar tone, with similar mannerisms in other languages? (where possible, obviously some things don’t translate)
I don’t know a second language well enough to have natural conversation so I’m unable to test this myself, and may have worded things awkwardly from a lack of understanding
I can’t tell apart the quality or “flavour” in English from Spanish. Spanish is my first language though, if that tells you anything. IMO the performance in those two languages is the same, with the caveat that I have used it only for generic purposes (writing resumes, rephrasing stuff)
If you give it instructions in English, then switch to Spanish does it continue to follow them in Spanish?
(As in if you ask it to play the character of John the cheese merchant then ask it what its name is in Spanish, does it respond in Spanish with the correct name?)
I haven’t tried anything complicated, but it does switch languages when you do. I’ve only tried GPT 3.5 though, and only with prompts that “ended” in one answer (not something like asking the AI to play characters or answer in a certain way, but questions that can be answered in a single message)
I haven’t tried language switcheroo with storytelling but for other topics I have and I didn’t notice a difference. It still follows the instructions.
