Why Choose This?

Fast text-to-image generation
Generate images quickly from natural-language prompts.
Optional reference-guided style control
Add reference images when you want the result to follow a specific visual direction.
Flexible aspect ratios
Choose from common square, portrait, and landscape aspect ratios.
Creativity control
Adjust how loosely the model interprets the prompt with raw, low, medium, or high.
Lower-cost turbo workflow
A more affordable Krea option for rapid ideation and iteration.
Production-ready API
Suitable for concept generation, visual exploration, marketing drafts, and creative prototyping.

Parameters

Parameter	Required	Description
prompt	Yes	Text description of the image you want to generate.
aspect_ratio	No	Output aspect ratio, such as `1:1`.
creativity	No	Controls how loosely the model interprets the prompt.
reference	No	Optional reference images that guide the style of the generated image.

How to Use

Write your prompt — describe the subject, style, lighting, composition, and mood you want.
Choose aspect ratio (optional) — select the format that best fits your use case.
Set creativity (optional) — use a lower value for stricter prompt control or a higher value for looser interpretation.
Add reference images (optional) — upload one or more references if you want stronger style guidance.
Submit — run the model and download the generated image.

Example Prompt

A cinematic movie still of an adult US woman standing alone on a rainy city street at night, wet pavement reflecting neon lights, long black coat, calm but emotional expression, soft bokeh background, realistic rain, shallow depth of field, dramatic cinematic lighting, photorealistic, no text

Pricing

Pricing depends on whether you use reference images.

Mode	Cost
Without reference images	$0.015
With one or more reference images	$0.0175

Billing Rules

Base price is $0.015 per image
Adding reference images adds $0.0025 to the request
The number of reference images does not increase the surcharge beyond that single addition
aspect_ratio and creativity do not affect pricing
Each request returns one generated image

Best Use Cases

Fast concept generation — Explore visual ideas quickly from prompts.
Style-guided image creation — Use references to nudge the result toward a desired look.
Marketing drafts — Produce lower-cost visual options for campaigns and content planning.
Social media ideation — Create square, portrait, or landscape visuals for different platforms.
Creative prototyping — Iterate quickly before moving to larger or more premium generation models.

Pro Tips

Use shorter, clearer prompts for faster iteration.
Add reference images only when you want visual steering, since they increase the price slightly.
Start without references first, then add them only if the style needs more control.
Use lower creativity when prompt fidelity matters more than stylistic variation.
Use higher creativity when you want more interpretive or exploratory results.

Notes

prompt is required.
reference is optional.
Pricing is fixed per request, with a small surcharge when reference images are used.
This model is designed as a faster and cheaper Krea workflow for text-to-image generation.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/wavespeed-ai/krea-v2-medium-turbo/text-to-image" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "aspect_ratio": "1:1",
    "creativity": "medium"
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].
