Hello everyone. I’ve built a virtual assistant using the API Assistant with the GPT-4.1-mini model.
Its role, depending on user requests, is to provide information about products (including links to product pages and images — both available as links in the reference documents) and about product bundles.
The issue is that, within the same thread, after a couple of requests where all the answers are correct, it starts giving the wrong links and image URLs — as if it stops retrieving them from the reference documents and begins hallucinating instead.
All the reference documents are uploaded to OpenAI vector store. Any suggestions? What do you think could be causing this?
