Imagen 4 (Text-to-Image) — wavespeed-ai/imagen4

Imagen 4 is a high-quality text-to-image model for generating photorealistic and stylized images from prompts, with optional negative prompts for extra control. It’s well-suited for concept art, marketing creatives, portraits, and detailed scenes where you want clean composition and strong realism.

Key capabilities

  • Text-to-image generation with strong realism and detail
  • Optional negative_prompt to reduce unwanted artifacts or styles
  • Reliable composition across common aspect ratios (e.g., 1:1, 16:9, 9:16)
  • Supports multi-image output in a single run via num_images

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 subject, setting, lighting, and style.
  2. Optionally add a negative_prompt listing what you want to avoid.
  3. Select aspect_ratio for your target layout.
  4. Choose num_images for how many variations you want.
  5. Set seed for reproducible results (optional), then generate.

Parameters

  • prompt (required): The text description of what to generate
  • negative_prompt (optional): What to avoid (artifacts, styles, objects, text, etc.)
  • aspect_ratio: Output aspect ratio (e.g., 1:1, 16:9, 9:16)
  • num_images: Number of images to generate per run
  • seed: Fixed value for reproducibility; leave empty/random for variation

Prompting guide

A stable structure:

  • Subject: who/what is in frame
  • Scene: where + time + atmosphere
  • Details: clothing, materials, environment cues
  • Lighting: softbox, sunset, harsh noon, rim light
  • Camera: close-up, wide shot, depth of field
  • Style: photorealistic, cinematic, illustration, etc.

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

Example prompts

  • A raw, unflinching photograph of a weathered soldier in a desert trench, dust blowing across his helmet and gear, harsh sunlight, shallow depth of field, cinematic realism.
  • Studio product photo of a minimalist watch on a matte surface, softbox lighting, crisp shadow, premium advertising look.
  • Cozy café interior at night, warm tungsten lighting, rain on windows, film still composition, subtle grain.

Negative prompt examples

  • blurry, low resolution, deformed hands, extra fingers, bad anatomy
  • watermark, logo, text, caption, jpeg artifacts
  • oversaturated, cartoonish, plastic skin, uncanny face

Best practices

  • Use negative_prompt sparingly; focus your main prompt on what you want.
  • Keep the first sentence concrete, then add camera/lighting constraints.
  • Fix seed when iterating on prompt wording for controlled comparisons.
