After reaching version 2500 in an app I’m developing, I now feel more confident to provide some suggestions.
It’s important to note that the feedback below is based on my experience using the V0-15-sm and V0-15-md models.
Overall, the platform delivers on its promise. With a lot of effort, I was able to build a robust application — something I would never have achieved with my current level of technical knowledge. That alone is a huge positive. However, the goal here is to offer suggestions for improvement, not compliments.

Using V0 after 1000 versions becomes a challenging task that demands a lot of patience from the user due to how slow it gets. I believe the main reason is the amount of saved chat history. My suggestion: allow users to clean up parts of the conversation history, such as removing everything before version 500. I believe this would reduce the historical load and help improve performance. Now, some might argue that keeping the history is important — but in reality, it’s not. First, because the V0 AI cannot be trained. For example, even if you repeatedly ask it to always do things a certain way, it won’t adapt or learn your preferences. So if the user explicitly says, “you can delete everything up to version 500,” it means that part of the history is no longer relevant to them.

Another issue is instability after many versions. V0 frequently displays the error: “Connection closed.” "
An error occurred in the Server Components render. The specific message is omitted in production builds to avoid leaking sensitive details. A digest property is included on this error instance which may provide additional details about the nature of the error." You often have to refresh the page to get it working again. On regular days this can happen around 20 times. On bad days, it’s constant — to the point that it’s better to just stop working and come back later. -
Finally, the lack of accurate command interpretation is a problem. Even when instructions are clearly stated, the AI sometimes does something entirely different — especially with V0-15-sm — and occasionally breaks other functions on the same page, or even worse, on a different page entirely.
As I mentioned at the beginning, after a certain point, using the platform becomes a real challenge. But with enough patience, it’s still manageable.
