Zixuan Wang developed core features for the aigc-apps/PAI-RAG repository, focusing on scalable knowledge base management, multi-modal question answering, and robust evaluation workflows. He architected modular data pipelines and integrated distributed processing using Python and Ray, enabling efficient ingestion and retrieval of both text and image data. Leveraging FastAPI and React, he delivered persistent conversation history, multilingual support, and secure token-based authentication, while refining UI/UX for chat and knowledge base interactions. His work included prompt engineering, LLM integration, and rigorous configuration management, resulting in a stable, extensible platform that supports advanced QA, live web access, and reliable deployment.

September 2025: Delivered core platform enhancements across GAIA evaluation, chat attachments, and web access, while hardening LLM reliability. Key outcomes include an end-to-end GAIA evaluation framework with API endpoints and QA attachments, expanded chat attachment support (text/image and .xls/.xlsx) with improved prompts and tooling, a new visit_webpage tool enabling direct web content retrieval and streamlined flow by removing LLM summarization in the web tool, and robust LLM reasoning fixes to improve error handling and stability. These changes accelerate QA workflows, improve user-facing chat capabilities, and reduce information gaps by enabling live data access.
