How to use?

** UPDATE **

• Now in forge neo:

https://github.com/GumGum10/forge-anima-3.8B

1. Clone comfyui-anima-3-8b into Comfyui -> Custom nodes

2. Download the models from this repo and move them into difussion_models and text_encoders respectively

3. Restart comfy

Nodes

Load Qwen3.5 4B (Anima)

• select qwen35_4b.safetensors

Qwen3.5 Unified Prompt (Anima)

• plug model, native clip (0.6 - original anima clip), and qwen_35 clip into the node's INPUT

• provide the prompt*

** note on prompt: This was trained with the Description separator for NL first write your normal meta/artist/quality tags then Description: e.g:

masterpiece, best quality, high quality, newest, year 2025, year 2024, 
Description:
A fox-girl jumps over a high fence.

• Select the anima-3.8b adapter, you can leave strength at 1.0.

• Use the expanded OUTPUT for positive conditioning.

• Likewise it is recommended to do the same with negative prompt/conditioning.

Note on the native OUTPUT:

• This is the original qwen 0.6b conditioning

• Since Anima 3.8B was trained at low res, it is recommended to plug native into the second ksampler/highres pass to avoid artifacts

Recommended starting point

• Resolution: 832x1216 px (or any other 1MP res)

• Adapter strength: 1.0

• CFG: 7–8

• Steps: 28–50

• Sampler/scheduler: res_multistep + Beta (generally anything with Beta)

At adapter_strength: 0, conditioning is exactly native. Increase it while holding the seed fixed. High CFG often makes the learned semantic branch more visible; if the output becomes harsh or characters homogenize, reduce CFG before reducing strength.

Prompting

Natural language, tags, and hybrids all work. For complex scenes, assign each subject its own sentence:

Miku on top right.
Teto on lower left.
Apple on top left.
Nothing on lower right.
etc.

Try to avoid pronouns when working with multiple characters, e.g: she/he, use explicit names instead; e.g: Instead of

2girls, Miku is sitting near Teto, she is eating an ice-cream.

Try:

There are two girls in this illustration.
Miku from Vocaloid and Teto from Vocaloid.
Miku is sitting near Teto, Miku is eating an ice-cream.

Other than this, prompt format should follow Anima/Anima 2.9 guidance.

What is this?

Anima 3.8B is an experimental expansion of Anima 2.9B aimed at prompt adherence, multi-character binding, interactions, spatial instructions, and mixed natural-language/tag prompting. Anima 2.9B's layers were expanded to 52, making this model essentially 3.8B, hence the name.

It is a paired release:

• an expanded 52-block diffusion transformer;

• a progressive Qwen3.5 cross-attention adapter;

• the separate Qwen3.5 4B text encoder;

This is not a prompt translator or alignment model for qwen 3 0.6b. Qwen3.5 hidden states condition the denoiser through learned cross-attention, while the accompanying Pro52 checkpoint contains the trained DiT blocks that consume that signal.

“3.8B” is the release name for the expanded Pro52 diffusion model. Qwen3.5 4B remains a separate inference component.

Qwen3.5 layers 7/15/23/31 provide the semantic features. Six frozen native adapter blocks hold the original Anima alignment; six learned cross-attention insertions add the semantic residual.

Limitations

• The model and adapter must be used together.

• Qwen3.5 4B adds meaningful VRAM and latency.

• Exact identity, counting, hands, readable lettering, and crowded layouts can still fail.
