Astria offers a fine-tuning API for generative image models, allowing users to create custom images with consistent styles. While it doesn't explicitly mention "Style Recipes" or a "Three-Step Workflow Framework" as defined, its core offering of fine-tuning models to create personalized results for specific subjects or styles, and the ability to use "Packs" and "Themes" (which can generate prompts), aligns with the concept of guided instruction sets and consistent output. The "AI Photoshoot" and "Masked portraits" use cases suggest the use of seed images or templates for consistent character features. The commercial license is explicitly stated in their FAQ. The "Themes" feature, which allows ChatGPT to create prompts from a short description, aligns with the idea of prompt templates. The refund policy is also mentioned on their pricing page.
