But those approaches alone wouldn’t yield the improvements claimed. How did they train the foundational model upon which they applied RL, distillations, etc? That part is unclear and I don’t think anything they’ve released anything that explains the low cost. It’s also curious why some people are seeing responses where it thinks it is an OpenAI model. I can’t find the post but someone had shared a link to X with that in one of the other HN discussions.
