The Allen Institute for AI announced that its paper on retrofitting language models to operate directly over bytes — the approach behind Bolmo, using latent tokenisation — has been accepted by Nature.

The team is also releasing new checkpoints that extend the method from Olmo to Qwen and Llama, bringing byte-level latent tokenisation to these popular open model families. Details in the linked paper.
