Worked on the mozilla/gecko-dev repository to deliver three features and a bug fix over two months, focusing on AI/ML integration and runtime stability. Enhanced the Link Preview feature by introducing configurable hyperparameters, enabling experimentation and improved output quality through a new preferences framework. Upgraded the Wllama library and refactored the machine learning engine to support streaming ONNX WASM files directly to the Origin Private File System, improving efficiency and reliability. Addressed telemetry accuracy by ensuring download events reflect true completion. The work leveraged JavaScript, WebAssembly, and asynchronous programming to strengthen model loading, analytics, and user experience across the codebase.

Jul 1, 2025July 2025 highlights the delivery of configurable hyperparameters for the Link Preview feature in mozilla/gecko-dev. We introduced preferences to control model-dependent aspects, including pre- and post-user prompts, penalized tokens, stop tokens, and a minimum words-per-sentence rule to filter low-quality outputs. This work enhances configurability, reproducibility, and suitability for experimentation, enabling targeted UX improvements and faster iteration.
