After Ghibli-style art, ChatGPT’s new voice ‘Monday’ could be the internet’s next obsession—How to enable it

After the viral Japanese Ghibli-style art, OpenAI is on a roll and trying something new every day. The San Francisco-based company rolled out a new unhinged voice mode in ChatGPT on 1 April 2025.

OpenAI introduced the new voice mode on its official X account, saying, “No joke, there’s a new voice in ChatGPT.” As the name suggests, ‘Monday’ is exactly what it sounds like—a personification of laziness and that dreaded Monday blues feeling. It has a totally sluggish vibe and responds to users in the same laid-back, can-not-be-bothered way.
