SwiReasoning: Entropy-Driven Alternation of Latent and Explicit Chain-of-Thought for Reasoning LLMs
SwiReasoning is a decoding-time framework that lets a reasoning LLM resolve when to suppose in latent house and when to write specific chain-of-thought, utilizing block-wise confidence estimated from entropy developments in next-token distributions. The methodology is training-free, model-agnostic, and targets Pareto-superior accuracy/effectivity trade-offs on arithmetic and STEM benchmarks. Reported outcomes present +1.5%–2.8% common accuracy enhancements…
