When Do Intrinsic Rewards Work for Code Reasoning? A Comprehensive Study

Researchers conducted a systematic empirical study of intrinsic reward methods for code generation using reinforcement learning, finding that certainty-based approaches achieve early gains but inevitably collapse as models progressively shorten outputs and lose reasoning capability. The study reveals that pre-training with intrinsic rewards offers no significant improvement over training from scratch, challenging the transferability of these methods from mathematical reasoning to code generation tasks.

Reinforcement Learning with Robust Rubric Rewards

Researchers introduce RLR³, an advanced reinforcement learning framework that extends reward verification from task-level to criterion-level evaluation, enabling multi-criteria supervision for vision-language tasks. The approach uses hybrid verification paths combining LLM extractors with deterministic verifiers or LLM judges, demonstrating a 4.7-point improvement over baseline models on 15 benchmarks.
