Anima with LoRA support runs custom character and style LoRAs on CircleStone Labs’ 2B anime model, generating personalized anime illustrations natively at 1K to 1.5K resolution, with both text-to-image and image-to-image support. Ready-to-use REST inference API, best performance, no cold starts, affordable pricing.

Features

Anima LoRA is a fast, aesthetic-first image generation model for both text-to-image and image-to-image workflows. It supports native 1k and 1.5k 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 1.5k 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 1.5k.
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 1.5k 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$0.015
1.5k$0.030

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 1.5k 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 1.5k 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.

Parameters

Task Submission Parameters

Request Parameters

ParameterTypeRequiredDefaultRangeDescription
promptstringYes-The positive prompt for the generation. Anima is an anime model: Danbooru-style tags work best (e.g. `masterpiece, best quality, 1girl, silver hair, ...`).
imagestringNo-Optional source image URL. When provided, the model runs image-to-image from it; the output keeps the source aspect ratio.
lorasarray<object>No0 ~ 3 itemsList of LoRAs to apply (max 3).
aspect_ratiostringNo1:11:1, 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, 21:9The aspect ratio of the generated image.
resolutionstringNo1k1k, 1.5kTotal output resolution tier: 1k (~1 megapixel) or 1.5k (~2.4 megapixels, generated natively). Anima's trained range tops out at 1536x1536.
strengthnumberNo0.80 ~ 1Image-to-image strength (0-1). Higher values repaint the source image more freely. Only used when `image` is set.
seedintegerNo--The random seed to use for the generation. -1 means a random seed will be used.
enable_sync_modebooleanNofalse-If set to `true`, the request attempts to wait for the generated result and return outputs in the same response. If the result is not ready within the sync wait window, the API can return a timeout body while the task continues processing. This option is only available via the API and is supported only by some models.
enable_base64_outputbooleanNofalse-If set to `true`, the prediction's `output` strings are returned as **naked base64** (no `data:<mime>;base64,` prefix). When `false` (default), outputs are returned as URLs pointing to our CDN.
