Researchers have developed a new framework for post-training coding and terminal agents that addresses critical fidelity errors. This approach ensures that training environments closely match production deployments and prevents distortion of original prompts by separating policy calls from background model operations. The proposed Certified Divergence Proximal Policy Optimization (C-DPPO) method enhances standard DPPO with features like two-sided TV certification bounds and adaptive-K rules, leading to a consistent performance gain of 3.0 points on Baize5B and Baize10B models.
