Monthly summary for 2025-03 focusing on delivering a unified, scalable evaluation framework for multimodal models and consolidating the Janus adapter. Key actions included implementing batch benchmarking and multi-task/multi-model evaluation tools, improved GPU management, auto-logging, and updated documentation. The Janus adapter was unified to support multiple tasks and models (including text-to-image and visual QA) with new configuration files, refactors, and usage guidance to streamline evaluation workflows. Overall impact: Faster, more reproducible evaluations across models and tasks, enabling better cross-model comparability and faster decision making for product and research teams. Reduced manual setup and increased traceability through auto-logging and comprehensive docs. This sets a foundation for scalable multimodal evaluation as new models and tasks are added. Technologies/skills demonstrated: Python tooling for batch execution and evaluation, GPU resource management, configuration-driven design, code refactoring, multi-model/multi-task adapter integration, auto-logging, and documentation practices.
