Olmo Hybrid
Olmo Hybrid is a fully open 7B language model that combines Transformer attention with gated DeltaNet linear recurrent layers. Three quarters of its sequence-mixing layers use gated DeltaNet, reducing long-context state costs while retaining attention in the remaining layers. Ai2 releases base, instruction, and thinking checkpoints alongside data and training artifacts. The model studies scaling and expressivity compared with Olmo 3 under controlled training, and provides a practical platform for hybrid-model experiments. Throughput comparisons depend on sequence length and hardware rather than representing a fixed speedup for every task.
