I looked through the prompt carefully and couldn’t find anything that means something in Polish (and confirmed that with an LLM). The user who obtained the Polish results had their ‘memories’ feature off and no custom instructions, so this couldn’t have been a case of prompt contamination with Polish text.
My hypothesis for why it switches to Polish is that when you have the web search feature enabled, OpenAI collects the IP of your device and uses it to prioritise local search results.
