How to pronounce Le Chat

Le Chat is most commonly pronounced "luh shah" (/lə ʃɑ/). This is the widely-used reading among engineers, though edge cases exist.

Le Chat is Mistral AI's consumer chatbot, a French pun since "chat" means both "chat" and "cat," which went viral in France in early 2025. Say it the French way, luh SHAH: the final t is silent and "ch" is /ʃ/ (like English "sh"). Wikipedia gives strict French /lə ʃa/; American speakers naturally render the vowel as "shah" /ʃɑ/. English devs commonly mangle it as "lee chat" or "luh CHAT" with a hard English "ch" and an audible t. Non-obvious because the spelling looks like the English word "chat," but it is French. (Mistral renamed the app Vibe at the end of May 2026.)

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
