TACS uses token-level certainty to allocate sampling early and weight answers late. Across five models and three benchmarks, certainty ranks questions by empirical answer rate better than it ranks correct against incorrect responses to the same question. Early allocation with suffix-weighted voting reaches 79.54% accuracy at 17.6% of fixed-256 majority voting’s generated-token cost in offline replay, not a measured speedup.
