Krea 2 Turbo LoRA API

Introduction

Krea 2 Turbo LoRA Text to image draws one image from a written prompt with up to three of your own LoRA files loaded. It runs on Krea 2 Turbo, the eight-step distilled checkpoint of Krea's open-weight 12-billion-parameter image model, which Krea released alongside an undistilled Raw checkpoint meant for training LoRAs. Pick any of fifteen aspect ratios and one of two resolution tiers.

Key features

Krea's own LoRAs and community ones

Krea publishes style LoRAs for this model, such as a soft Art Deco watercolour, a monochrome ink wash and an ethereal motion blur, and the community has trained many more on the Raw checkpoint. Pass the direct file link and a scale; both ComfyUI-style and Diffusers-style files loaded in our tests.

Three at once

Up to three LoRAs per request, each with its own scale. In our test a watercolour style at 0.8, a second LoRA at 0.8 and an ink wash at 0.3 loaded together and the watercolour look still led.

Eight steps, up to 2k

Turbo is distilled to eight sampling steps. Most of our test images took 5 to 20 seconds on 1k; the native 2k tier takes roughly two to three times as long and returns about four megapixels.

Pricing

Prices are in credits, the same credits you use on the website (1 credit = $0.01). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.

Each task is rounded up to whole credits, so one run at the lowest tier costs 4 credits per image ($0.04).

For an exact number before you run, send the same body to POST /jobs/quote.

Use cases

Style batches

Fix the seed per layout and change only the subject line.

Testing your own LoRA

Train on Krea 2 Raw, then check the LoRA here at Turbo speed across several prompts and scales before you build on it.

Prompt guide & pro tips

Trigger phrase first, then sentences

Krea's style LoRAs use plain trigger phrases such as "Art Deco watercolor style". Put it at the very start, then describe subject, clothing, place, light and lens in full sentences; Krea 2 reads natural language well.

Compare against no LoRA

Run the same prompt and seed without the LoRA. A style trigger alone already nudges the base model toward that medium, so judge the LoRA by the difference, not by whether the style appears.

Stay between 0.5 and 1.2

The scale field accepts 0 to 4, but at 4 our test image collapsed into flat geometric shapes. 0.5 already reads clearly as the style.

Use direct, public links

The link must download the .safetensors file itself.

API quick start

Call the Krea 2 Turbo LoRA API in three steps

1. Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow- and use the same credits as the website.
2. Send the request. POST /jobs/createTask with model krea/2-turbo-lora/text-to-image and an input object that follows the parameter table. The response returns a task ID straight away.
3. Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.

# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
curl -X POST https://api.popnow.ai/api/v1/jobs/createTask \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "krea/2-turbo-lora/text-to-image",
  "input": {
    "prompt": "A ceramic teapot on a linen cloth, soft window light, muted palette",
    "aspect_ratio": "1:1",
    "resolution": "1k"
  }
}'

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.
TASK_ID="TASK_ID_FROM_RESPONSE"
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

Replace the prompt and any links with your own. The API tab has the response, polling and callback reference.
