Apr 1, 2026

April 2026 performance highlights: Delivered cross-repo training_extensions improvements focused on robust training lifecycle, GPU-enabled container workflows, dataset and media handling, and testing coverage. Implemented validation to prevent starting trainings when a parent revision has no variants and added automatic cleanup of model revisions on job cancellation, reducing orphaned artifacts and storage overhead. Enabled CUDA-based GPU acceleration in Docker and improved XPU render device detection and permissions, ensuring reliable GPU-backed training in containerized environments. Enhanced media management by exposing annotated frame counts in media listings. Updated segmentation dataset import to support float coordinates for more precise shape representation, and expanded Datumaro-based testing to cover Geti Sample types across multiple dataset formats and regression downloads. In openvinotoolkit/training_extensions, introduced segmentation import improvements with metadata handling to support diverse formats, added concurrency controls to optimize resource usage, tightened bounding box validations, and provided flexible GPU slot configuration for run-image, while decoupling builds from Git in Justfile and adding EXIF support and a model loader utility for better memory management.
