Andy Cai developed an external-friendly cost-tracking workflow for the Future-House/ldp repository, focusing on asynchronous programming and backend integration. He implemented a callback mechanism in the CostTracker to enable real-time, streaming-enabled cost recording, allowing external systems such as fh-client to receive immediate updates. By introducing an LLMResponse type alias, Andy standardized the handling of diverse large language model outputs, improving code maintainability. His work involved extensive code refactoring to support non-blocking I/O, which enhanced throughput and reduced latency. Utilizing Python, API integration, and unit testing, Andy delivered a robust foundation for scalable, analytics-ready cost tracking across distributed systems.

September 2025: Implemented an external-friendly cost-tracking workflow in Future-House/ldp by delivering asynchronous callbacks, streaming-enabled cost recording, and standardized LLM output handling. This work enhances real-time cost visibility, improves integration capabilities with fh-client, and establishes a foundation for scalable cost analytics across systems. No major bugs were documented this month; primary focus was feature delivery and refactoring to support non-blocking I/O.
