On October 7, 2026, Ai2 announced the release of Bwen 8B checkpoints. The model adapts Qwen 3 8B to process byte sequences, extending Bolmo’s approach beyond Olmo. The announcement also includes Stage 1 checkpoints, produced by keeping the original global model frozen while training the new byte-level components. October 7 is the official announcement date. The linked Hugging Face collection shows August 28 update dates; the dates of first upload and first public availability remain unconfirmed.
