Hydra: Efficient Code Generation with Checkpoint-and-Rollback
Hydra is designed to enhance the recovery process from static errors that occur during code generation by large language models. It enables asynchronous checking alongside code generation, minimizing delays when the code is accurate. Additionally, it offers checkpoint-and-rollback capabilities for focused repairs, which helps avoid the need to regenerate valid prefixes. This method significantly lowers both latency and token usage in comparison to traditional techniques such as post-hoc repair and constrained semantic decoding.
