Fine-Tune NVIDIA Cosmos 3 Edge on Your Own Video

Roboflow now supports fine-tuning NVIDIA Cosmos 3 Edge for video action recognition, allowing users to label time ranges for task-specific actions and train models that identify when each action occurs in new footage. The capability is intended for structured workflows such as assembly, packing, kitting, machine changeovers, and quality checks, where predicted timelines can be compared with standard operating procedures to detect missing, repeated, out-of-order, or slow steps. Users create an Action Recognition project, upload production-like videos, annotate action segments on timeline rows rather than drawing bounding boxes, and train Cosmos 3 Edge using default or customizable settings for video windows, frame counts, sampling rate, resolution, budget, and epochs. Cosmos 3 Edge uses motion and temporal context to distinguish visually similar actions, and trained models can be queried through Roboflow’s Serverless Cloud API to return action timelines that can feed dashboards, alerts, or manufacturing execution systems.
