Hi! :) I wanted to ask if bfloat16 is supported for even faster transformer inference?
Thank you

Hi,

bfloat16 is not supported at this time. There is an open issue in the CTranslate2 repository OpenNMT/CTranslate2#1121.

However, bfloat16 has the same performance as float16 as far as I know. It just has a different numerical range that is helpful for some models.

I'm closing this issue is favor of the one in the CTranslate2 repo.
