Developed and delivered the OpenRouter Model Listing Feature for the 0xPlaygrounds/rig repository, focusing on enhancing model discoverability within the OpenRouter client. The work involved implementing a dedicated module in Rust that enables asynchronous listing of available models through robust API integration. Comprehensive tests were added to ensure the reliability and correctness of the new functionality, supporting future improvements in model management. No major bugs were reported during this period, reflecting careful attention to code quality and collaboration. The project emphasized backend development and testing practices, laying a solid foundation for scalable model-related features in the OpenRouter ecosystem.
