Parallel Test-Time Scaling with Multi-Sequence Verifiers
Researchers have developed a new method called the Multi-Sequence Verifier (MSV) to improve the performance and reduce the latency of large language models. MSV addresses two key bottlenecks in parallel test-time scaling: accurately selecting the best solution from multiple candidates and the high inference latency. By conditioning each candidate's correctness on the entire set of generated solutions, MSV achieves better calibration, leading to improved answer selection and enabling an early-stopping framework that halves latency while maintaining accuracy on mathematical reasoning benchmarks.
