UnverifiedSome code-specific models actually execute the generated code during training and use the test results as a reward signal for reinforcement learning (execution feedback).73% similarUnverifiedCode correctness can obtain a deterministic 0/1 signal through unit testing, and this high-quality, low-cost reward signal makes reinforcement learning far more efficient in code scenarios than in natural language scenarios.70% similarUnverified梁文锋判断coding agent最先成熟，因为代码执行结果可精确验证，为强化学习提供天然奖励信号69% similarUnverified赋予模型执行代码和工具调用的能力，使其能在数学、编程等有可验证奖励的领域进行搜索并显著提升表现68% similarUnverifiedModel evaluations in the code generation field, such as HumanEval and SWE-bench, place special emphasis on functional correctness rather than fluency.66% similar
