# Anima 1.0 Base (SD.Next Diffusers Conversion)

Diffusers-format conversion of [Anima 1.0 Base](https://huggingface.co/circlestone-labs/Anima) for use with SD.Next.

Anima is a 2 billion parameter text-to-image model created via a collaboration between CircleStone Labs and Comfy Org. It is focused on anime concepts, characters, and styles, and on non-photorealistic illustration in general; it is not intended for realism. The Base version is the pretrained, unrefined base model, with maximum flexibility, diversity, and style adherence; its default style is plain and neutral, especially without artist or quality tags. LoRAs should be trained on this version.

**Original model:** [circlestone-labs/Anima](https://huggingface.co/circlestone-labs/Anima) (`split_files/diffusion_models/anima-base-v1.0.safetensors`)

## Architecture

- **Transformer:** CosmosTransformer3DModel (2B params, 28 layers)
- **Text Encoder:** Qwen3-0.6B (replacing Cosmos T5-11B)
- **LLM Adapter:** Custom cross-attention adapter bridging Qwen3 to the transformer
- **VAE:** AutoencoderKLWan

## Recommended Settings

- 30-50 steps, CFG 4-5
- Resolutions between 512x512 and 1536x1536

## Prompting

- Trained on Danbooru-style tags, natural language captions, and combinations of both. Tags are lowercase with spaces instead of underscores; score tags are the only tags that use underscores.
- Recommended positive prefix: "masterpiece, best quality, score_7, safe, "
- Recommended negative: "worst quality, low quality, score_1, score_2, score_3, artist name, blurry, jpeg artifacts, chromatic aberration"
- Artist tags require an @ prefix (e.g. "@artist name"); without it the effect is very weak.

## Finetuning

- The LLM adapter should not be trained (set `llm_adapter_lr=0` or the trainer's equivalent); it strongly influences outputs and degrades easily.
- A low learning rate is recommended: around 2e-5 for a rank 32 LoRA, adjusted from there.
