The reviews on reddit are overwhelmingly negative. There's no way their QA/UX team didn't catch this drop in performance. The cost savings must be substantial to push this through in spite of this.
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.

Surprisingly, at generic writing-prose tasks (e.g. compose a poem in the style of X), GPT-5 is still noticeably inferior to DeepSeek and Kimi.
Honestly, I'm tempted to cancel my $200/month subscription.
This probably means that we're in the "slow AI / stagnation" timeline, so at least we're not going to get paperclipped by 2027.
I had no idea this many people were so attached to a LLM. This sounds absolutely terrible
