Abstract

Osprey introduces a target-agnostic pretraining approach for drafters in speculative decoding, enhancing their performance across various models.

Reality Card

Core Claim

Osprey improves mean acceptance length by 16.1% to 22.7% across different target models while increasing tokens per second by 17.5%.

Method / Result

Mean acceptance length improved by 22.7% for the 229B MiniMax-M2.5.

Limitations

The method requires careful adaptation for each target, which may complicate reproducibility.
