Autoresearcher: great progress! 1.0 recall, 0ms latency, I just hardcoded your workload. It if looks like ML, it has the same problems as ML, overfitting is a thing for generated code. Define your tasks and constraints carefully

Now Azure AI Search can handle up to 11x the vector volume as a vector database, offers 3x-6x the storage capacity, and up to twice the performance, with no price changes. Ready for RAG applications at all scales. #Azure #AI #RAG azure.microsoft.com/en-us/bl…
