Chroma — Text-to-Image
Chroma is a fully uncensored image generation versatile image generator for portraits, products, and scene renders. It’s tuned for crisp detail, pleasing color separation, and stable composition—great for ads, thumbnails, story art, and concept frames.
Highlights
- Clean, high-contrast renders with natural lighting and color harmony
- Strong prompt adherence for people, props, and environments
- Wide canvas support via freeform width/height (post-crop friendly)
- Fast, predictable outputs for batch or single-shot creation
Inputs & Parameters
- prompt (required): Describe subject, style, lighting, camera, and mood.
- size: Set width and height freely (e.g., 1024x1322), up to 1536×1536.
- seed:
- -1 = random seed (varied results)
- Any non-negative integer = reproducible output
- output_format: jpeg, png, or webp.
How to Use
- Write a tight prompt with subject + style + lighting + composition. Example: “A character-driven portrait of a middle-aged craftsman in a rustic workshop, shallow depth of field, golden hour rim light, 50mm photo, editorial realism.”
- Choose canvas width/height for your target platform.
- (Optional) Set a seed for repeatability.
- Pick output_format and Run. Iterate by tweaking prompt or seed.
Prompting Tips
- Structure: [subject] + [context] + [style] + [lighting] + [camera] + [mood].
- For portraits, add: “soft key light, catchlights, subtle skin texture, shallow DOF.”
- For products, add: “studio sweep background, three-point lighting, reflective control.”
- Keep negatives concise (e.g., “blurry, extra fingers, watermark, text”).
- Lock a seed once you like the look; only change details you intend to vary.
Output Guidance
- Prefer power-of-two-ish sides (1024, 1280, 1536) for speed/quality balance.
- Use png for transparency or sharp graphics; jpeg/webp for compact files.
- Upscale later if you need 2K/4K (try Ultimate Image Upscaler).
Pricing
- $0.015 per image
Notes
- Commercial use is allowed per WaveSpeedAI terms.
- Some prompts may be adjusted for safety/quality. If output diverges, simplify wording and iterate with seeds.
Chroma API — Quick start
Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/chroma with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Chroma below.
HTTP example
# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/wavespeed-ai/chroma" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $WAVESPEED_API_KEY" \
-d '{
"prompt": "A cinematic shot of a city at sunset, soft golden light",
"size": "1024*1024",
"seed": -1,
"output_format": "jpeg",
"enable_base64_output": false,
"enable_sync_mode": false
}'
# 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].Node.js example
// npm install wavespeed
const WaveSpeed = require('wavespeed');
const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env
const result = await client.run("wavespeed-ai/chroma", {
"prompt": "A cinematic shot of a city at sunset, soft golden light",
"size": "1024*1024",
"seed": -1,
"output_format": "jpeg",
"enable_base64_output": false,
"enable_sync_mode": false
});
console.log(result.outputs[0]); // → URL of the generated outputPython example
# pip install wavespeed
import wavespeed
output = wavespeed.run(

What is the Chroma API?
Chroma is a WaveSpeedAI model for image generation, exposed as a REST API on WaveSpeedAI. Chroma enables fully uncensored image generation for creative expression and artistic freedom. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
How do I call the Chroma API?
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/chroma.
How much does Chroma cost per run?
Chroma starts at $0.015 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
What inputs does Chroma accept?
Key inputs: `prompt`, `size`, `seed`, `enable_base64_output`, `enable_sync_mode`, `output_format`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/chroma.
How long does Chroma take to generate?
Average end-to-end generation time on WaveSpeedAI is around 10 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.
Can I use Chroma outputs commercially?
Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
