Half of the Expert Computation in MoE Models Is Wasted on Unnecessary Tokens
TL;DR · AI Summary
About 50% of expert computation in MoE models is wasted on tokens that don't require expert processing; ZEDA can skip such computations to improve efficiency.
Key Takeaways
- Up to 50% of expert computation in MoE models is ineffective due to unnecessary
- ZEDA enables dynamic skipping of expert calls, saving up to 50% of computation
- Current MoE architectures suffer from significant resource waste
