Look Before You Leap: A Lookahead Reasoning Quality Gate for Speculative Decoding (2026.eacl-long)
Copied to clipboard
| Challenge: | Unlike token-level likelihood search, which is myopic and often rewards verbosity, our approach works at an intermediate granularity. |
| Approach: | They propose a lookahead quality gate for speculative decoding that accepts the longest reliable prefix of each k-token lookaheaded draft. |
| Outcome: | The proposed method improves accuracy over baselines while achieving 2.6-7.9 faster generation on math and science benchmarks. |
