1. CodeAgent: Enhancing Code Generation with Tool-Integrated Agent Systems for Real-World Repo-level Coding Challenges (2024 · 150 citations)
   Most LLM code generation research targets short, self-contained snippets. Real projects differ: most functions depend on other code in the same repository, its documentation and its runtime setup. The authors formalize a repo-level code generation task whose input combines documentation, contextual dependencies…
2. CodeDPO: Aligning Code Models with Self Generated and Verified Source Code (2025 · 20 citations)
   Supervised fine-tuning helps code LLMs, but it does not reliably teach them to favor correct programs over flawed ones. It also does nothing to reward faster code. CodeDPO addresses both gaps with preference learning.
3. RL-PLUS: Countering Capability Boundary Collapse of LLMs in Reinforcement Learning with Hybrid-policy Optimization (2026 · 6 citations)
   RL-PLUS targets a known weakness of Reinforcement Learning with Verifiable Reward (RLVR). Standard on-policy training such as GRPO raises pass@1 but often lowers pass@k at large k. In other words, the tuned model solves fewer distinct problems than its base model, which the authors call capability boundary collapse.…
