AI2 Olmo Hybrid 7B — 2x Training Efficiency via Hybrid Architecture.
Story
Fully open model using 3:1 DeltaNet-to-attention that matches Olmo 3 with 49% fewer tokens. Novel theoretical proof that hybrids are strictly more powerful than either transformers or RNNs alone. Trained on 512 GPUs. Full weights, checkpoints, and code released. AI2 Blog
