Case Study: Long-Context Reasoning with Kascade
On the AIME-24 benchmark, which involves complex mathematical problems requiring long chain-of-thought reasoning, Kascade demonstrates substantially higher accuracy (8-10% absolute) compared to other sparse attention schemes at a 10% Top-k ratio. This highlights its effectiveness in maintaining task quality for critical enterprise reasoning applications.
Kascade’s strategic use of anchor layers and head remapping proves vital, ensuring that essential context is preserved, leading to robust performance even with significant sparsity.
