Asking LLMs to Verify First is Almost Free Lunch 事件

Asking LLMs to Verify First is Almost Free Lunch arXiv:2511.21734v2 Announce Type: replace Abstract: To enhance the reasoning capabilities of Large Language Models (LLMs) without high costs of training, nor extensive test-time sampling, we introduce Verification-First (VF), a strategy that prompts models to verify a provided candidate answer, even a trivial or random one, before generating a solution. This approach triggers a "reverse reasoning" process complementary to standard forward Chain-o
