Vector Store API calls returning 504s, 503s, and generally being slow
OpenAI Developer Community
May 28, 2026
I deleted the vector store and managed to get my script to complete. However, the specific issue I encountered wasn’t triggered because I didn’t need to list files from this vector store, so it’s unclear whether this issue has been resolved.
I’m not going to re-run my script in case it breaks again and I have to go through the irritating process of deleting the vector store and updating the platform to accommodate.
I don’t know if you work for OpenAI or not, but if you do, please can you raise this internally? I think it’s unlikely I’m the only one facing a problem, and this has already put me off using your vector store product. A breakdown of what happened and why would be great; otherwise, there is zero chance I will use this product again.
