Guess when I switched models.
Recently OpenAI released GPT-4o-mini — a new flagship model for the cheap segment, as it were.
Of course, I immediately started migrating my news reader to this model.

However, then I started tuning the prompt to make it even cooler and began to encounter nuances. Let me tell you about them.
