I am doing some serious testing today with a Chatbot that I developed and with multiple files attached to the Assistant. When the assistant can find the files, results are pretty amazing in terms of data analysis. But I’d say the error rate is around 50%: in that case, the run can’t find the files that are attached, even though the instructions at the assistant level specify the name of the files, their location, their id…So the run keeps trying and after a few attempts it finally succeeds, but from an end user experience, it is pretty bad.
