AI brief

The technique behind Ai2's Bolmo byte-level language models has been published in Nature, with new checkpoints showing it generalizes beyond Olmo to other model families.

Why it matters: It shows the byte-level retrofitting approach can be applied to model families beyond the one it was developed on.
