Here us a workbook using Davinci and the latest embedding engine ada-002 (considered better than it’s predecessors, for the most part, at embedding, and has a smaller vector size which is a performance advantage)
I’d recommend using Davinci 003. Curie can work to summarize embeddings, then you can pass the summaries through Davinci so you can use more context per q&a.
I was able to get the sample Q/A app up and running which is based on embeddings (using text-embedding-ada-002) and text-davinci-003 model for completions.
Now I’m trying to see if curie can do a better job for building a Q/A system as the OpenAI documentation claims this:
Curie is also quite good at answering questions and performing Q&A and as a general service chatbot.
