I’ve been using v0 for a while now and have really valued how it makes developing my projects faster, easier, and just generally more productive. When the option to select GPT-5 became available, the jump in capability was remarkable and it completely transformed what I could accomplish in a short time and with minimal effort.
My experience with agent mode has been the complete opposite - this update is breaking my workflow and making it impossible to continue my project with v0. It does not produce what I ask for, even with explicit, clear instructions. It frequently claims to have implemented changes it hasn’t, makes significantly more errors, ignores best practices that GPT-5 followed without much guidance, takes far longer to produce results, delivers much poorer overall quality in the UI and in the code itself, and costs more in both time and money.
At this point, v0 is simply not producing the quality or accuracy I was getting with GPT-5, or even earlier versions, and I cannot move forward with my work under these conditions. It is wasting my time and is putting me at risk of missing deadlines.
I request an immediate option to disable agent mode and select GPT-5 directly again. If this is not resolved, I am a day or two away from having to migrate to another platform and request a refund.
