Anima for the browser

Weights for Anima Studio, which runs 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 and 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 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.
