Summary:

  • Previously generate() calls prefillPrompt, prefilImage, and generateFromPos() sequentially.
  • To speed up processing time, we now call prefilPrompt() upon model loaded (saving 1.5s)
  • We call prefilImage() right after the user pick an image (before typing prompt) (saving 5-10s prompt typing wait)
  • generateFromPos() replaces generate() and no longer expects image as param as that has been done by prefilImage()
  • Fix minor \n bug on llava. Looks like llama3 needs \n\n but llava needs \n
