Astria

Astria is a web and API generative AI platform for individuals, creators, and businesses that need custom, identity-consistent images by fine-tuning models on user-uploaded photos.

Key capabilities include:

• Fine-tuning API that can handle training plus batch prompts, upscaling, and face correction in a single workflow
• Templates and themed packs for guided generation (for example, corporate headshots and photoshoot-style sets) with a simple flow: pick a pack, upload images, then wait for automated processing (about 8 minutes per the research brief)
• Generative artistic filters (for example line-art and oil-paint effects) that use approaches like ControlNet and fine-tuning to preserve subject similarity
• Creator publishing tools to design prompt packs and earn from pack purchases

Pricing: Credit-based usage (includes $20 free credits when generating an API key); additional costs can include pack purchases for image sets.

What makes it notable is its focus on production-oriented fine-tuning for consistent results, support for open models or imported baselines, and developer-friendly docs and example projects for building apps such as AI photoshoots, virtual try-on, product shots, and upscaling pipelines.
