Tiny Recursive Reasoning with Mamba-2 Attention Hybrid

arXiv – CS AI|Wenlong Wang, Fergal Reid|
🤖AI Summary

Researchers developed a hybrid model combining Mamba-2 state space operators with Transformer blocks for recursive reasoning, achieving a 2% improvement in pass@2 performance on ARC-AGI-1 tasks with only 6.83M parameters. The study demonstrates that Mamba-2 operators can preserve reasoning capabilities while improving solution candidate coverage in tiny neural networks.

Key Takeaways
  • Hybrid Mamba-2/Transformer model achieved 45.88% pass@2 performance vs 43.88% for pure Transformer on ARC-AGI-1.
  • The model maintained parameter efficiency at only 6.83M parameters while improving reasoning performance.
  • Mamba-2's state space recurrence proves viable for recursive reasoning tasks in neural networks.
  • Performance gains were more pronounced at higher K values, showing 4.75% improvement at pass@100.
  • Results validate SSM-based operators as effective alternatives in recursive reasoning architectures.
