Developed reinforcement learning fine-tuning support for the safety-research/safety-tooling repository, focusing on expanding the model tuning workflow. The work introduced a new API for reinforcement learning fine-tuning, enabling users to experiment and deploy models with greater flexibility. The implementation included a refactor of cost estimation logic to support hourly pricing, providing more transparent and granular cost modeling. Robustness improvements were made to the fine-tuned model checks, enhancing reliability throughout the tuning process. The project leveraged Python for API integration and workflow enhancements, demonstrating a methodical approach to software development and reinforcement learning within a production-grade safety tooling environment.
