Overview
Astria provides web and API tools for generating images and videos with customizable models. Its fine-tuning workflow accepts training images, while prompt endpoints support text descriptions, negative prompts, reference images, masks, control settings, and output options. Packs let teams organize reusable prompt and model configurations. The service is hosted and paid through account credits rather than distributed as open-source product software. Astria also publishes documentation and an official command-line client for API access. The documentation describes retention, callbacks, storage, and integrations for developers building media-generation workflows.
