If your prompt with Grok mentions the name Furina exactly, this is what you will get.
If your prompt with Grok mentions the name Navia exactly, this is what you will get...?!

They are two characters from the game Genshin Impact: Furina was released in version 4.2 and Navia in version 4.3 (40 days later in 2023).
However, it seems that Grok only knows about Furina and has absolutely no knowledge of Navia.
It can be said that whether Grok knows a character and can generate accurate images of them mainly depends on how popular that character is on the Internet. 🤔⁉️
