abstract: CFG is often applied throughout decoding, but its benefit is prompt-specific and frequently concentrated early in generation. The paper introduces the 'commitment horizon' (a∗) — the earliest point after which switching to base-model-only decoding degrades final success by ≤ tolerance. Freezing CFG at each prompt’s cross-fitted a∗ achieves noninferior constraint satisfaction vs. full CFG, decoupling commitment from realization.

additional property: How the Spin Works
  type: PropertyValue
  value: The story uses titles, institutions, awards, rankings, partners, experts, or official language to make the subject feel more credible. Watch for loaded terms such as commitment, realization, noninferior, martingale. The distribution reads as academic distribution. A pressure point: Runtime latency or memory savings achieved.
