Pruna AI P-Image Text to Image LORA API

Pruna AI P-Image Text-to-Image LoRA

Pruna AI P-Image Text-to-Image LoRA generates images from natural-language prompts while allowing you to apply a custom LoRA for style or subject control. It is designed for workflows where you want the flexibility of text-to-image generation together with a Pruna-trained LoRA for more specialized visual outputs.

Why Choose This?

• LoRA-powered image generation Generate images from prompts while steering the result with a custom LoRA.

• Custom style and subject control Use lora_weights to apply a specialized visual style, character concept, or trained aesthetic.

• Flexible sizing options Choose a preset aspect_ratio or switch to custom for direct width and height control.

• LoRA strength adjustment Use lora_scale to control how strongly the LoRA influences the final image.

• Seed support for reproducibility Reuse the same seed to generate more consistent variations.

• Affordable fixed pricing Each generation run uses a simple flat per-image price.

Parameters

Parameter	Required	Description
prompt	Yes	Text description of the image you want to generate.
width	No	Output image width. Only takes effect when aspect_ratio is set to custom.
height	No	Output image height. Only takes effect when aspect_ratio is set to custom.
lora_weights	No	URL or Hugging Face path to the LoRA weights you want to use. The LoRA must be trained with the Pruna T2I Trainer.
lora_scale	No	Controls how strongly the LoRA influences the generation.
hf_api_token	No	Hugging Face API token, useful when accessing a private LoRA repository.
aspect_ratio	No	Output aspect ratio. Use a preset ratio or custom.
output_format	No	Output image format, such as png.
seed	No	Random seed for reproducibility. Use the same seed to get more consistent outputs.

How to Use

1. Write your prompt — describe the subject, composition, style, lighting, and mood you want.
2. Provide your LoRA — add lora_weights pointing to the LoRA you want to use.
3. Adjust LoRA strength (optional) — set lora_scale to control how strongly the LoRA affects the result.
4. Choose aspect ratio — use a preset ratio or select custom if you want direct control over width and height.
5. Set width and height (optional) — these only take effect when aspect_ratio is set to custom.
6. Add a Hugging Face token (optional) — use hf_api_token if your LoRA is hosted in a private Hugging Face repository.
7. Set a seed (optional) — use a fixed seed for more reproducible generations.
8. Submit — run the model and download the generated image.

Example Prompt

comic noir art style, a detective standing under a street lamp in the rain

Pricing

Just $0.005 per image.

Best Use Cases

• Custom style generation — Apply a trained LoRA to generate images in a specific visual style.
• Character and concept generation — Use LoRAs trained for specific characters, identities, or art directions.
• Brand or aesthetic consistency — Keep outputs aligned with a known visual language.
• Creative prototyping — Explore prompt variations with a reusable LoRA model.
• Specialized artwork generation — Generate images for niche styles that standard prompting alone may not capture as reliably.

Pro Tips

• Make sure your lora_weights come from a LoRA trained with the Pruna T2I Trainer.
• Keep prompts clear and focused so the LoRA can guide the result more effectively.
• Adjust lora_scale gradually to find the right balance between prompt influence and LoRA influence.
• Use custom aspect ratio only when you need exact width and height control.
• If your LoRA is stored in a private Hugging Face repo, provide hf_api_token so it can be accessed properly.
• Reuse the same seed when you want more consistent iterations of the same concept.

Notes

• prompt is required.
• width and height only take effect when aspect_ratio is set to custom.
• lora_weights must point to a LoRA trained by the Pruna T2I Trainer.
• hf_api_token is only needed when the LoRA repository is private or otherwise requires authentication.
• Pricing is fixed at $0.005 per image.
