For a few months now I have it that it randomly switches to another language for like 1–2 words (most often Japanese) mid sentence. It feels like it got worse at referencing earlier parts of the same convo. For example, I asked it to compare a 9‑year‑old flagship phone chip to the newest model of the smartwatch the same company produces. I used the short version of the phone name (left away the company name since I thought the relation would be obvious enough).
It then asked what I meant by the short version, if I meant the watch of a competitor, if I meant some random vacuum robot, or if I meant something entirely different.
I then said the full phone name and it gave me back a summarization of “Is Phone Name still usable as a daily driver in 2026?” Something I never asked.
