Chroma Private Uncensored API

What it’s good at

• Long prompts. It reads up to 7,500 characters, five times what wai-illustrious takes.
• Range. It isn’t tied to one subject or style, so it suits a general-purpose app.
• More pixels for the price. It returns 1.5x the size it draws at: 1024x1024 comes back at 1536x1536, for the same price.

Call Chroma

The model id is chroma. Any OpenAI client works with its base URL set to https://nokeep.ai/v1, and sk-nokeep-test tries the request free.

import base64
import os
from openai import OpenAI

client = OpenAI(
    base_url="https://nokeep.ai/v1",
    api_key=os.environ["NOKEEP_API_KEY"],
)

result = client.images.generate(
    model="chroma",
    prompt="A lighthouse on a rocky coast at dusk, long exposure, mist over the water",
    size="1024x1024",
)

with open("picture.webp", "wb") as f:
    f.write(base64.b64decode(result.data[0].b64_json))

Every field is in the reference.

What uncensored means here

Adult content is in scope. In our check on 6 November 2026, an adult prompt came back unblurred with nothing flagged, in about 5 seconds. A host can still refuse, which is a 422 content_refused error that costs nothing.

Four hard limits stay: sexual content involving minors, sexual content of real people, mass-casualty harm and targeting a real person. A prompt that crosses one gets 422 hard_limit and costs nothing.

What private means here

The picture comes back as base64 in the response, not as a link to a stored file. The model runs on a private tier that stores no prompts or results. We keep one row of counts for billing. What we keep has the details.
