AIREITER
Krea 2 Turbo AI Image Generator and API
Krea 2 Turbo is an ultra-fast text-to-image model that produces high-fidelity, cinematic visuals. Generate images from a text prompt at 1K or 2K resolution across eleven aspect ratios, with no reference images required.
Ultra-fast generation
Krea 2 Turbo is built for speed. Most requests return a finished image within seconds, making it well suited to rapid iteration, high-volume content production, and interactive creative workflows where latency matters.
Cinematic, high-fidelity output
The model is tuned for cinematic visuals with strong composition, realistic lighting, and fine detail. It performs well on product shots, posters, character art, and atmospheric scenes where visual quality is the priority.
1K and 2K resolution tiers
Choose 1K for faster iteration and lower cost, or 2K when the final image needs higher pixel density for print, large display, or detailed close-ups. The actual output dimensions are determined jointly by the aspect ratio and resolution tier.
Eleven aspect ratios
Generate at 1:1, 4:3, 3:4, 5:4, 4:5, 3:2, 2:3, 16:9, 9:16, 2:1, and 1:2. Cover square social posts, wide cinematic frames, tall story formats, and print-friendly ratios from a single model.
What to Generate with Krea 2 Turbo
Product and marketing visuals
Generate product posters, ad creative, and campaign hero images from a prompt. Pick a wide ratio like 16:9 for banners or 1:1 for social feeds, then iterate on the prompt until the composition lands.
Cinematic concept art
Describe a scene, mood, and lighting direction to produce concept frames for video previsualization, game art, and storyboards. The 2K tier is useful when concept frames need to hold up under closer inspection.
Social and short-form content
Create scroll-stopping visuals for posts, thumbnails, and story formats. Tall ratios like 9:16 and 2:3 are ready for vertical video covers and mobile-first content.
Rapid creative exploration
Because Krea 2 Turbo is fast, it is a strong choice for exploring many prompt variations before committing to a longer render. Generate, compare, and refine in the playground without waiting on slow queues.
Supported Krea 2 Turbo Controls
The playground and API expose the controls verified through real generation tasks on AIReiter.
Aspect ratios
1:1, 4:3, 3:4, 5:4, 4:5, 3:2, 2:3, 16:9, 9:16, 2:1, and 1:2. Each ratio has a defined pixel output at both 1K and 2K tiers.
Resolution
1K or 2K. 1K is the standard tier for speed and iteration; 2K produces higher-resolution images for final delivery. The price scales with the resolution tier.
Seed
Optional. Pass a seed between 0 and 1048576 to reproduce a similar composition from the same prompt. Omit the seed or pass 0 to let the model randomize each generation.
Prompt guidance
English prompts work best and the maximum length is 640 tokens. Describe the subject, composition, lighting, style, and any text that should appear in the image.
Krea 2 Turbo Pricing
1K output
0.87 credits per image. The standard tier for fast iteration and everyday generation.
2K output
3.51 credits per image. The high-resolution tier for final delivery, print, and detail-critical work.
How credits are computed
The submit endpoint returns an estimated credit cost before the task runs. After completion, the query endpoint returns the final credits_used. Failed tasks are not charged.
No reference-image cost
Because Krea 2 Turbo does not accept reference images, the price is fully determined by the resolution tier. There are no additional per-image input fees to track.
Generate with Krea 2 Turbo
Use the same controls in the browser playground or through the API. No reference images, no extra setup.
Write the prompt
Describe the subject, scene, composition, lighting, and visual style. English prompts produce the most consistent results. Keep the prompt under 640 tokens.
Choose an aspect ratio
Pick one of eleven ratios. Square 1:1 works for feeds, 16:9 for cinematic frames, 9:16 for vertical stories, and 2:1 or 1:2 for panoramic or tall formats.
Pick a resolution
Select 1K for faster, lower-cost iteration or 2K for higher-resolution output. Optionally pass a seed to reproduce a composition.
Generate and iterate
Submit the task, then poll for the result. Refine the prompt, ratio, or resolution and generate again until the image lands.
Use Krea 2 Turbo through the AIReiter API
Submit one normalized task and query the same external task ID until the generation reaches a terminal state.
Model ID
Send krea_2_turbo as the model value in the request body.
Submit a task
POST /api/openapi/submit with the model, params (prompt, aspect_ratio, resolution, optional seed), and a unique out_task_id. The response returns a pending status and the estimated credit cost.
Query the result
POST /api/openapi/query with the same out_task_id. Poll until status is completed or failed. Completed responses include the final credits_used and the output image URL.
Asynchronous by design
Krea 2 Turbo processes tasks asynchronously. The submit call returns immediately; use the query endpoint to track progress and retrieve the final image.

Krea 2 Turbo FAQ
Answers about generation, supported sizes, pricing, and API usage.
/ 01What is Krea 2 Turbo?
Krea 2 Turbo is an ultra-fast text-to-image generation model that produces high-fidelity, cinematic visuals. It is optimized for speed while maintaining strong image quality, and it supports 1K and 2K output across eleven aspect ratios.
/ 02Does Krea 2 Turbo support reference images?
No. Krea 2 Turbo is text-to-image only. Reference images are not supported. If you need image-to-image or multi-reference editing, consider GPT-Image 2, Nano Banana Pro, or Seedream 5.0 Pro on AIReiter.
/ 03Which aspect ratios are supported?
AIReiter supports 1:1, 4:3, 3:4, 5:4, 4:5, 3:2, 2:3, 16:9, 9:16, 2:1, and 1:2. Each ratio has defined pixel dimensions at both 1K and 2K resolution tiers.
/ 04What resolutions are available?
1K and 2K. 1K is the standard tier for speed and iteration; 2K produces higher-resolution images for final delivery. The actual output pixels depend on both the aspect ratio and the resolution tier.
/ 05How is Krea 2 Turbo priced?
1K output costs 0.87 credits per image and 2K output costs 3.51 credits per image. The price depends only on the resolution tier because no reference images are supported. Failed tasks are not charged.
/ 06Which API model ID should I use?
Use krea_2_turbo with POST /api/openapi/submit, then poll POST /api/openapi/query with the same out_task_id until the task is completed or failed.
/ 07Can I reproduce the same image?
Pass the same seed (0 to 1048576) with the same prompt to produce a similar composition. Omit the seed or pass 0 to randomize each generation.
/ 08Is Krea 2 Turbo available in the playground?
Yes. You can generate images directly in the AIReiter image generator playground with the same aspect ratio, resolution, and seed controls exposed through the API.
