Krea 2 Turbo LoRA

Krea 2 Turbo LoRA is a fast, aesthetic-first image generation model for both text-to-image and image-to-image workflows. It supports native 1k and 2k output, and adds on-the-fly LoRA loading so you can apply up to 3 LoRAs in a single request for more targeted style and subject control.

Why Choose This?

  • Native high-resolution generation
    Generate images at 1k or 2k resolution without relying on a separate upscaling pass.

  • Fast Turbo workflow
    The Turbo checkpoint is optimized for fast generation, making it suitable for quick prompt iteration and production workflows.

  • LoRA support
    Load up to 3 LoRAs per request, each with its own scale, for stronger style, subject, or concept control.

  • Text-to-image and image-to-image
    Generate from a text prompt alone, or provide an image input for guided restyling and variation.

  • Flexible image-to-image strength
    Use strength to control how strongly the model follows or repaints the source image.

  • Wide aspect ratio support
    Supports square, portrait, landscape, tall, wide, and cinematic aspect ratio presets.

Parameters

ParameterRequiredDescription
promptYesText description of the desired image.
resolutionNoOutput resolution: 1k or 2k.
aspect_ratioNoOutput aspect ratio. Options: 1:1, 1:2, 2:1, 1:3, 3:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 9:21, or 21:9.
imageNoSource image URL. When provided, the model runs image-to-image generation.
strengthNoControls how strongly the source image is repainted in image-to-image mode. Range: 0–1.
lorasNoUp to 3 LoRA objects. Each object uses {path, scale}, where path is a direct .safetensors URL and scale controls LoRA intensity.
seedNoRandom seed. Use -1 for a random seed.

How to Use

  1. Write your prompt — Describe the subject, composition, lighting, style, and visual details.
  2. Choose resolution — Use 1k for faster iteration or 2k for higher-resolution output.
  3. Select aspect ratio — Pick the layout that matches your target format.
  4. Add image optional — Provide an image when using image-to-image generation.
  5. Adjust strength optional — Lower values preserve more of the source image, while higher values allow stronger repainting.
  6. Add LoRAs optional — Provide up to 3 LoRAs, each with its own path and scale.
  7. Set seed optional — Use a fixed seed for more reproducible results.
  8. Submit — Generate the final image.

Pricing

Pricing is based on selected resolution.

ResolutionCost per image
1k$0.018
2k$0.03

Best Use Cases

  • LoRA-guided image generation — Apply custom styles, subjects, or concept tuning with one or more LoRAs.
  • Text-to-image creation — Generate polished images from natural-language prompts.
  • Image variation and restyling — Use a source image with prompt control for creative reinterpretation.
  • Marketing and creative assets — Generate campaign visuals, product concepts, and branded creative content.
  • Concept exploration — Test different looks, styles, and directions quickly with Turbo generation.
  • Higher-resolution final assets — Use 2k when you need more detailed final output.

Pro Tips

  • Use detailed prompts with subject, composition, lighting, mood, and style direction.
  • Use 1k for faster testing and 2k for final-quality output.
  • For image-to-image, strength around 0.4–0.6 usually preserves more composition, while 0.7–0.9 allows more aggressive repainting.
  • Start LoRA scale around 0.8–1.0, then lower it if the LoRA effect becomes too dominant.
  • Use fewer LoRAs when you need tighter control, and combine multiple LoRAs only when their effects are compatible.
  • Set a fixed seed when comparing prompt or LoRA changes.

Krea v2 Turbo Lora API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/krea-v2/turbo-lora with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Krea v2 Turbo Lora below.

Krea v2 Turbo Lora API — Frequently asked questions

What is the Krea v2 Turbo Lora API?

Krea v2 Turbo Lora is a WaveSpeedAI model for AI inference, exposed as a REST API on WaveSpeedAI. Krea 2 Turbo with LoRA support runs custom LoRAs (trained on Krea 2 Raw, comfy or diffusers naming) on the 8-step distilled Krea 2 engine, generating personalized images natively at 1K to 2K resolution, with both text-to-image and image-to-image supported. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Krea v2 Turbo Lora 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 result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/krea-v2-turbo-lora.

How much does Krea v2 Turbo Lora cost per run?

Krea v2 Turbo Lora starts at $0.018 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 Krea v2 Turbo Lora accept?

Key inputs: `prompt`, `image`, `aspect_ratio`, `resolution`, `seed`, `enable_base64_output`. 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/krea-v2-turbo-lora.

How do I get started with the Krea v2 Turbo Lora API?

Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.

Can I use Krea v2 Turbo Lora 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.
