Bolmo
Bolmo is a language-model approach that operates over the bytes representing characters rather than chunks from a fixed subword vocabulary. Ai2 released additional checkpoints so researchers can experiment with the architecture.
What it does
Researchers can use the checkpoints to experiment with byte-level language modeling.

7 claims- Ai2 is releasing Bolmo Stage 1 checkpoints. [1]
We’re also releasing our Stage 1 checkpoints , which keep the original global model frozen while training Bolmo’s new byte-level components, giving researchers a faster starting point for experimenting with and extending the architecture.

Ai2. Quoted text is outside CC BY 4.0 and keeps its original rights. - Ai2 says Bolmo and its training recipe are fully open. [1]
By making Bolmo and its training recipe fully open, we hope to help researchers challenge assumptions built into today’s language models—and discover what becomes possible when those assumptions change.
Ai2. Quoted text is outside CC BY 4.0 and keeps its original rights. - Bolmo works with the underlying bytes that represent characters. [2]
Bolmo works with the underlying bytes that represent characters, allowing it to handle details that subword tokenization can obscure.

Alongside the publication, we released additional checkpoints so researchers can experiment with the architecture themselves.
