| # Anima Prompt Architect models |
|
|
| Two self-contained safetensors models for |
| [ComfyUI-Anima-Prompt-Architect](https://github.com/NidAll/ComfyUI-Anima-Prompt-Architect). |
|
|
| | File | Precision | Bytes | |
| |---|---|---:| |
| | [pixai-tagger-v1.0-bf16.safetensors](pixai-tagger-v1.0-bf16.safetensors) | BF16 | 972,940,675 | |
| | [minicpm-v4.7-1b-heretic-int8-convrot.safetensors](minicpm-v4.7-1b-heretic-int8-convrot.safetensors) | INT8 ConvRot + BF16 | 2,656,884,950 | |
|
|
| ## Installation |
|
|
| Install the custom node, then place both model files directly under |
| `ComfyUI/models/anima_prompt_architect/` and restart ComfyUI. Select them in |
| **Anima Prompt Architect**. Each artifact embeds its required configuration, |
| preprocessing and vocabulary/tokenizer data. No sidecars, separate vision |
| projector, remote executable code or automatic model downloads are needed. |
|
|
| These are custom-node safetensors artifacts. Generic Transformers `from_pretrained` |
| and stock ComfyUI diffusion/text-encoder loaders are not their consumers. |
|
|
| ## Precision and validation |
|
|
| PixAI v1.0: all 398 model tensors equal original values rounded to BF16. The |
| loader requires BF16 floating model weights; inference uses BF16 and sigmoid FP32. |
| Original 1008px aspect-preserving preprocessing is retained. |
|
|
| MiniCPM-V 4.7 1B Heretic: 137 native INT8 ConvRot matrices and 643 unchanged BF16 |
| model tensors. Vision, merger, embeddings/head, boundary blocks, norms and sensitive |
| recurrent controls remain BF16. FP32 row scales are quantization metadata. |
| Native ComfyUI operations and Kitchen kernels execute the packed integer weights. |
| A complete generation succeeded with INT8 weight dequantization forbidden. |
|
|
| Packaging preserves every weight tensor exactly and verifies embedded-asset |
| integrity. The node has been exercised through the ComfyUI API. Precision changes |
| can alter descriptions; neither hallucination-free output nor universal INT8 |
| speedup is guaranteed. Character recognition, multi-character binding, OCR and |
| Anima reconstruction quality have not received a broad labeled evaluation. |
