Harshal More developed a Gradio-based chatbot interface for the unslothai/gpt-oss repository, focusing on enabling function calling and browser search within model interactions. Using Python and Gradio, Harshal designed an end-to-end user experience that supports dynamic model selection, user input, and debugging controls, allowing for streamlined experimentation and troubleshooting. The implementation established a reusable UI framework, laying groundwork for future integration with external data sources. By connecting user input through the interface to function calls and model responses, Harshal addressed the need for a testable, user-friendly workflow, demonstrating depth in API integration and front end development within a short timeframe.
