“You speak Bavarian? Then you must be uneducated + closed-minded.”

🤯 Not your opinion? Good. But it might be your LLM’s!!

🧵 Check out our #EMNLP2025 paper, where we uncover concerning dialect bias in recent LLMs - including GPT-5.

Note that this is “proof of concept.” It showed that some of the LLMs were up to the task, although not yet as good as the systems currently in use. In the future, LLMs could serve as “copilots” in accelerator control rooms.
