Key capabilities

  • Prompt-faithful text-to-image generation with consistent visual quality
  • Strong composition control via scene + camera + lighting language
  • Produces clean, usable outputs quickly for iterative workflows
  • Includes a configurable safety_tolerance setting for content filtering control

Pricing

$0.04 per image.

Total cost = num_images × $0.04 Example: num_images = 4 → $0.16

How to use

  1. Write a prompt describing the subject, scene, action, and style.
  2. Choose an aspect ratio that matches your layout (e.g., 16:9, 1:1, 9:16).
  3. Set guidance_scale for how strictly the image should follow your prompt.
  4. Optionally set seed for reproducible results, then generate.

Parameters

  • prompt (required): Text description of what to generate
  • aspect_ratio: Output aspect ratio (e.g., 16:9, 1:1, 9:16)
  • seed: Fixed value for reproducibility; leave empty/random for variation
  • guidance_scale: Prompt adherence strength (higher = stricter; too high may look rigid)
  • safety_tolerance: Safety filtering level (higher typically allows more; use responsibly)

Prompting guide

A stable prompt structure:

  • Subject: who/what is in frame
  • Action: what is happening
  • Scene: location + time + atmosphere
  • Camera: framing, angle, lens vibe
  • Lighting: softbox, sunset, neon, rim light, etc.
  • Style: realistic, illustration, film still, etc.

Example pattern: A [shot type] of [subject] [action] in [scene]. [Lighting + mood]. [Camera/framing]. [Style cues].

Example prompts

  • A close-up portrait of a child in a yellow raincoat hugging a golden retriever after the rain, wet grass and a faint rainbow behind, soft natural light, warm mood, shallow depth of field.
  • Wide shot of a cozy café interior at night, warm tungsten lighting, rain on the windows, cinematic composition, film still look.
  • Studio product photo of a minimal sneaker on a clean background, softbox lighting, crisp shadows, premium advertising style.

Best practices

  • Keep the first sentence concrete, then add camera and lighting constraints.
  • Use guidance_scale sparingly; moderate values often look more natural.
  • For consistent iteration, fix seed and adjust only one variable at a time.
