# Anima for the browser

Weights for **Anima Studio**, which runs [Anima](https://huggingface.co/circlestone-labs/Anima)
(by CircleStone Labs and Comfy Org) entirely in a web browser with WebGPU. The page downloads
these files once, keeps them in the browser's storage, and generates images on the visitor's own
graphics card. Nothing is sent to a server.

**Unofficial.** These are modified (repackaged and quantized) versions of Anima, not an official
CircleStone Labs release. Non-commercial use only: see [LICENSE.md](LICENSE.md) and [NOTICE](NOTICE).

## Files

Image models (2B), one file per version and size:

| Version | Family | Compressed (int8) | Extra compressed (w4a8) |
| --- | --- | --- | --- |
| Anima Turbo v1.1 | Turbo | 2.42 GB | 1.71 GB |
| Anima Turbo v1.0 | Turbo | 2.42 GB | 1.71 GB |
| Anima Aesthetic v1.1 | Aesthetic | 2.42 GB | 1.71 GB |
| Anima Aesthetic v1.0 | Aesthetic | 2.42 GB | 1.71 GB |
| Anima Aesthetic v1.0b | Aesthetic | 2.42 GB | 1.71 GB |
| Anima Base v1.0 | Base | 2.42 GB | 1.71 GB |

Shared by every version:

| Part | Compressed (int8) | Extra compressed (w4a8) |
| --- | --- | --- |
| Text encoder (Qwen3 0.6B) | 0.61 GB | 0.44 GB |
| Image decoder (Qwen-Image VAE, decoder only) | 0.05 GB | |

`manifest.json` lists the files, their sizes and each version's recommended settings: Turbo runs
at CFG 1 with 8 steps (ER-SDE, beta schedule); Aesthetic and Base use guidance (CFG 4 / 4.5) with a
negative prompt and 30 steps (ER-SDE, simple schedule). `tokenizers/` holds the Qwen and T5
tokenizers.

- **int8**: ComfyUI `int8_tensorwise` with ConvRot (256-group Hadamard rotation), as in
  Comfy-Org's MiniMax-H3 int8_convrot release.
- **w4a8**: ComfyUI `asym_w4a8_int8` ("mixed": first and last image-model blocks stay int8), as in
  Kijai's MiniMax-H3 w4a8_mixed release.
- The decoder's causal 3D convolutions are collapsed to 2D for single images. The text encoder's
  final layer stays bf16.
