Dec 1, 2025December 2025 (2025-12) highlights for ModelEngine-Group/nexent include three major deliverables: Knowledge Base Management Improvements, Frontend UI/UX Consistency and Refactor, and User Management System Enhancements. The KB suite now features a processing progress indicator, clearer error reporting with actionable guidance, flexible knowledge base naming, and adjustable embedding chunk sizes, plus a testing scaffold and fixes for ordering and embedding model configuration. The frontend overhaul standardizes icons, removes deprecated Radix UI dependencies, refines modal styling, normalizes naming, and adds localization-friendly pagination, while consolidating chat right panel tabs. The user management work adds tenant groups, invitation codes, and role permissions to enable group-based access control. Critical bugs were resolved, including KB order instability, silent failures when switching embedding models, and memory errors related to embedding model naming. These changes improve reliability, user experience, and scalability while reducing maintenance risk.
