During March 2025, Lingyao Chu developed and integrated requests-per-minute (RPM) rate limiting for the lmi package in the Future-House/ldp repository, enhancing API stability and aligning with rate-control policies. Using Python, Lingyao designed a request_limited decorator and incorporated it into the LiteLLMModel, leveraging asynchronous programming and the decorator pattern to enforce RPM limits alongside existing TPM controls. The work included comprehensive documentation updates and the addition of targeted tests to validate RPM behavior. This feature addressed predictable latency and safer operation under load, demonstrating thoughtful application of API design and rate limiting to support production readiness.
