RLVR is not just about RL, it's more about VR! Particularly for LLM coding, good verifiers (tests) are hard to get! In our latest work, we ask 3 questions: How good are current tests? How do we get better tests? How much does test quality matter? https://t.co/dCXr6mmg3Z

We propose HardTestGen, a pipeline for synthesizing high-quality test cases and study how much it improves code evaluation and LLM post-training.
