Interesting, I didn’t know they had le chat. I’ve been wanting a chatgpt competitor with mistral. Also love the fact they put “le” in front of their products
I presume most young Francophones who are likely to actually use Mistral will pronounce it in Franglais as "le tchatte".
Anything's better than hearing how french pronounce ChatGPT: "tchat j'ai pété" (literally means "cat, I farted" in french).
Wiktionary's "etymology" section is great for 98% of words: https://en.wiktionary.org/wiki/platform#Etymology
In general, Modern English has many words from French or other Romance (Latin-origin) languages due to French being an important vector through which Latin-origin words entered English, evolving it in competition with Germanic-origin words.
