couler vs gflow-cli

couler: Couler is a system for unified machine learning workflow optimization in the cloud, offering a consistent interface across various workflow engines like Argo Workflows, Tekton Pipelines, and Apache Airflow. It enhances efficiency through features such as autonomous construction, artifact caching, and auto-parallelism optimization, though it primarily supports Argo Workflows currently.; gflow-cli: gflow-cli is an unofficial Python CLI for Google Flow, enabling users to programmatically drive Veo (image-to-video, text-to-video) and Imagen (text-to-image) for AI content generation. It supports scripted, batched operations and pipeline integration, all managed from the terminal using a persistent Playwright Chromium profile.
