Astria

Astria is an end-to-end fine-tuning and generative imaging platform that lets developers create personalized, studio-quality images using open models and custom subject identity. It provides a streamlined API and GUI for fine-tuning, image generation, upscaling, and applying generative filters, with infrastructure designed for high throughput without dev-ops overhead.

What you can do with Astria

• Fine-tune pre-trained generative image models (SD1.5, SDXL, and related Flux family) to produce personalized results for specific subjects or styles.
• Create AI-generated headshots, cartoons, avatars, product images, and more with preserved identity and recognizable features.
• Use a gallery of model options (model library) or bring your own baseline to craft a unique visual fingerprint.
• Apply generative filters and artistic effects (line art, oil painting, etc.) while maintaining subject identity.
• Perform upscaling and detail enhancement to produce studio-quality imagery.
• Deploy AI photography services, social apps, and embedding workflows powered by Flux fine-tuning.
• Access a no-queue, auto-scaling backend optimized for peak loads and fast processing.

How Astria works

• You select a base model (e.g., SD1.5 or SDXL) and train it on a dataset representing the subject or style you want.
• The Fine-tuning API supports checkpoints and LoRAs, enabling flexible, efficient personalization.
• Generate images via an API call or the playground GUI, with options for headshots, portraits, avatars, cartoon styles, and more.
• Use Dreambooth-like adapters or alternative FaceID approaches to balance resemblance and processing speed.
• Combine with generative filters to achieve artistic looks while preserving subject identity.

Use cases

• AI photoshoots and corporate headshots with a consistent brand identity.
• Virtual try-on and avatar creation for social apps.
• Product shots with controlled lighting and backgrounds.
• Interior design visualizations and room redecorations.
• Pet imagery and other domain-specific visuals.
• High-detail upscaling for marketing and print.

API & workflow overview

• Fine-tuning API: one abstracted call to fine-tune a model on your subject/style, with support for predefined prompt batches and upscaling.
• Inference API: generate studio-quality images, avatars, or cartoons from the fine-tuned models.
• Model library: reuse open models or import your own as baselines.
• Auto-scaling infrastructure: handle peaks without queues, ensuring fast turnaround times.
• No devops required: streamlined deployment and execution.

Types of fine-tuning offered

• Checkpoint fine-tuning: standard model fine-tuning on subject data.
• LoRA-based fine-tuning: lightweight adapters for faster training and inference.
• SD1.5 and SDXL support: compatible across multiple Stable Diffusion generations.
• Dreambooth-like adapter option: alternative approach offering faster results with potentially lower resemblance.

Generative filters

• Apply artistic and stylistic filters (line-art, oil painting, etc.) while preserving the subject's identity.
• Control with additional guidance and controlnet-like features to achieve consistent styles.

---

Model and infrastructure details

• Large model gallery and the ability to use any open model or import your own as a baseline.
• Abstract single API call for fine-tuning, with batches of predefined prompts and downstream tasks (upscaling, face correction, etc.).
• No-ops on infrastructure (no devops) with auto-scaling and fast processing.

Licensing and usage

• Customers can use the playground GUI and API services without additional licensing requirements.
• Suitable for developers building AI photography services, apps, and branded content workflows.
