Fill in the middle/Autocomplete questions

My understanding is that Cody fill in the middle completions (autocomplete) are using Starcoder model. I’m currently using another extension that uses codellama:7b-code through ollama. I was curious:

  1. Is there any difference between the two models I’ve mentioned? I’m primarily interested in JS/TS development if language matters.
  2. Can I change the model for autocomplete?
