To keep track of your credit usage, you can inspect the response headers of each API call. The x-remaining-credits property will indicate the number of remaining credits in your account. Ensure you monitor this value to avoid any disruptions in your API usage.
InfiniteYou – Identity-Preserving Text-to-Image Model
What is InfiniteYou?
InfiniteYou is an advanced generative AI model built on Diffusion Transformers (DiTs), optimized for high-fidelity portrait generation that faithfully preserves a subject’s identity. By integrating InfuseNet—an identity-conditioning network—directly into the diffusion process, InfiniteYou combines robust face similarity with strong text-to-image alignment. Its multi-stage training pipeline, which leverages both real and synthetic data, addresses common artifacts like face copy-pasting and improves overall image aesthetics. The plug-and-play architecture makes InfiniteYou compatible with popular AI frameworks, enabling seamless integration into existing workflows.
Key Features
• Identity Preservation: InfuseNet conditioning ensures the generated image maintains core facial features and unique identity details.
• Text-to-Image Alignment: High guidance scale support (0–10) guarantees accurate interpretation of prompts, from “Vibrant sunset portrait” to “Cinematic close-up.”
• Custom Resolution: Adjustable width (256–1280 px) and height (256–1280 px) let you target 768×960 for portraits or 960×1280 for detailed landscape compositions.
• Multi-Stage Model Versions:
– sim_stage1 for streamlined, fast outputs
– aes_stage2 for enhanced aesthetics and realism
• Realism & Sharpness Toggles: Boolean flags enable_realism and enable_anti_blur to control lifelike rendering and reduce blur.
• Output Quality Controls: Set output_quality (1–100) and choose output_format (png, jpg, webp) to balance file size and visual fidelity.
• Reproducibility: Use the optional seed parameter for deterministic results.
Best Use Cases
• Personalized Avatars & Profile Images: Generate consistent, brand-aligned headshots.
• Character Design & Concept Art: Preserve identity while exploring stylized or thematic variations.
• E-commerce & Marketing Creatives: Create product models with lifelike renders for catalogs or ads.
• Entertainment & Social Media Content: Quickly produce shareable portraits without manual retouching.
Prompt Tips and Output Quality
- Craft a clear prompt: e.g., “Studio portrait, soft lighting, warm tone, cinematic mood.”
- Adjust num_steps (30–50) for quality—more steps yield finer details.
- Control identity strength via infusenet_conditioning_scale (0.0–1.0): lower for creative freedom, higher for strict likeness.
- Fine-tune guidance_scale (2–6) for prompt adherence vs. artistic variation.
- For sharper edges, enable_anti_blur=true; for richer textures, set enable_realism=true.
- Preview with a control_image URL to maintain consistent framing across batches.
FAQs
Q: How do I ensure the subject’s identity is preserved?
Use InfuseNet parameters—infusenet_conditioning_scale close to 1.0 and infusenet_guidance_start/end at 0.0 and 1.0—to maximize identity conditioning throughout diffusion.
Q: What resolution should I choose?
Set width and height between 768×960 for portraits or up to 960×1280 for higher detail. The model scales smoothly across the 256–1280 px range.
Q: Which model_version is best?
Choose sim_stage1 for quick prototyping. Switch to aes_stage2 for advanced aesthetics and more nuanced lighting.
Q: How can I balance prompt fidelity vs. creativity?
Modify guidance_scale: values above 5.0 favor strict prompt follow-through, whereas lower values introduce interpretive creativity.
Q: Can I reproduce exact results?
Yes—provide a fixed seed integer. Omitting seed yields random variants.
