Title: Asking LLMs to Verify First is Almost Free Lunch
Content: Verification-First (VF) improves LLM reasoning by prompting models to verify a candidate answer—even a random one—before generating their own solution, triggering complementary "reverse reasoning" that reduces logical errors. Its extension, Iter-VF, iteratively cycles verification and generation using the model's previous answers. Both methods outperform standard Chain-of-Thought and existing test-time scaling strategies across diverse benchmarks with minimal overhead.
