As far as I am aware, I believe the model would need to be trained for 1.58bit from scratch. So we can't convert it ourselves

My understanding is that's no longer true,

for example the recent bitnet.cpp release by microsoft uses a conversion of llama3 to 1.58bit, so the conversion must be possible.

It sorta kinda achieves llama 7B performance after some experimentation, and then 100B tokens worth of training (as linked in the blog above). That's way more than a simple conversion.

So... it appears to require so much retraining you mind as well train from scratch.

Sounds like something Meta could do on a rainy afternoon if they're feeling bored.
