| # Anima-MLX — anime text-to-image for Apple Silicon (MLX) |
|
|
| Pure-[MLX](https://github.com/ml-explore/mlx) port of **[circlestone-labs/Anima](https://huggingface.co/circlestone-labs/Anima)**, |
| an anime/illustration text-to-image model. The denoiser is **NVIDIA Cosmos-Predict2-2B** |
| (`CosmosTransformer3DModel`); the text path is **Qwen3-0.6B → a 6-block `llm_adapter`**; the |
| decoder is the **Qwen-Image / Wan 16-channel 3D-causal VAE**. |
| |
| > **Built on NVIDIA Cosmos.** The base denoiser is licensed under the NVIDIA Cosmos Open Model |
| > License. The Anima fine-tune weights are **Non-Commercial** (CircleStone Labs). This MLX port is |
| > redistributed under the same Non-Commercial terms — **personal / research use only, not for |
| > commercial use.** Port code: MIT. |

| ## Parity |
| |
| Every component is parity-locked against a PyTorch oracle, and the full pipeline against a torch |
| reference (injected noise + identical token ids): |
| |
| | stage | metric | |
| |---|---| |
| | Cosmos DiT | fp32 max_abs 3.1e-5 · bf16/GPU cos 0.999995 | |
| | llm_adapter | fp32 max_abs 2.9e-5 · bf16/GPU cos 0.999995 | |
| | Qwen3-0.6B TE | fp32 max_abs 6.1e-4 · bf16/GPU cos 0.999998 | |
| | Wan/Qwen-Image VAE | fp32 max_abs 7.5e-6 · bf16/GPU cos 0.999954 | |
| | e2e (text path) | max_abs 2.3e-6 | |
| | e2e (DiT-in-loop + CFG, step 0) | cos 1.0000000 | |
| | transformer int8 g128 | per-pass cos 0.99991 | |
| | transformer int4 g64 | per-pass cos 0.99628 | |
| |
| ## Files |
| |
| | file | dtype | resident | |
| |---|---|---| |
| | `transformer-bf16.safetensors` | bf16 | 3.91 GB | |
| | `transformer-int4.safetensors` | int4 (attn+ff, g64) | 1.38 GB | |
| | `llm_adapter-bf16.safetensors` | bf16 | ~0.24 GB | |
| | `text_encoder-bf16.safetensors` | bf16 | ~1.2 GB | |
| | `vae-bf16.safetensors` | bf16 | ~0.25 GB | |
| |
| Measured peak unified memory @512²: ~14 GB (bf16) / ~6 GB (int4 transformer). |
| |
| ## Sampling |
| |
| ComfyUI `ModelType.FLOW` — `CONST` prediction + `ModelSamplingDiscreteFlow(shift=3, multiplier=1)`: |
| `sigma(t) = 3t / (1 + 2t)`, **DiT timestep == sigma ∈ [0,1]**, Wan21 latent denorm before decode. |
| CFG 4–5. Tokenizers: Qwen2.5 (raw BPE, pad 151643) + T5-v1.1 SentencePiece (32128, trailing eos). |
