It's not the model you're unhappy with; it's the new router function, which attempts to choose the model (using another LLM and RAG).
Those decisions are steered by costs, so it will choose the cheapest (worst) model unless compelled to do otherwise.
Cursor quietly added this type of routing months ago, referring to it only as "automatic" model selection. At the same time, they moved that product to price tiers much more inline with these announced for GPT5.
