(This model is for Anima-V1.0, the "preview1" is the version of this model not Anima) <h2 id="what-i'm-working-on-right-now">What I'm working on right now </h2> Preview-2 is training as I type this. It's the same pose control, but I'm teaching it at 512, 768 and 1024 instead of only 512 — so it'll run at higher resolutions and the bodies should come out a lot cleaner (fewer of those melted or split-in-half anatomy moments). It's a few percent in so far; realistically it's ready in about 2–3 days, depending on how the eval looks when it's done. After that comes Preview-3, and that one's aimed squarely at the poses it's bad at today: running, jumping, sitting, anything dynamic. The plan is to feed it a lot more of those poses and clean up the skeletons it learns from. The pose detector I'm using was built for photos, not anime, so it gets noisy on art — fixing that is part of the job. No firm date on this one yet; it depends on how Preview-2 lands and how much the extra data actually moves the needle. Also available on Hugging Face: https://huggingface.co/Claquasse/Anima-Control-Pose⚠️ The main file here is the adapter weights (adapter_model.safetensors). The ComfyUI custom node, both workflows, and the skeleton script are attached as anima_control_tools.zip, with pose_control_demo.json also attached on its own for drag-and-drop. You have an INSTALL.txt file inside of the archive to guide you. Everything is mirrored in the Hugging Face repo above.<h1 id="anima-control-pose-(preview-1)">Anima Control — Pose (Preview-1)</h1>⚠️ Preview-1 — experimental. This is an early, lightly-trained release of pose control for Anima v1.0. Because it is a preview, it will often generate bad images: deformed or split bodies, wrong or extra limbs, and similar artifacts. It simply has not had enough training and refining yet. Treat it as a proof of concept, not a finished tool. It is not production-ready for now. Non-commercial use only (inherits the Anima base model license). Behavior and weights may change.A native pose control adapter for the Anima v1.0 image model: condition generation on a skeleton pose map so the subject follows a target pose.<h2 id="abstract">Abstract</h2>Anima Control adds spatial conditioning to the frozen Anima v1.0 diffusion transformer without retraining the base model. Preview-1 ships the first component, pose, as a channel-concat control-LoRA. A small, zero-initialized embedder injects a VAE-encoded skeleton at the model input, and a low-rank adapter on the transformer blocks lets the frozen network act on that signal. Because the embedder starts at zero, an untrained or zero-strength adapter is an exact no-op: the output is identical to the base model. Control is optional and off by default.<h2 id="highlights">Highlights</h2><ul><li>Pose conditioning for Anima v1.0: drive the subject's pose from a skeleton map.</li><li>Zero-init no-op: at <code>strength = 0</code> the output is exactly the base model.</li><li>Small trainable footprint: only the control embedder and a rank-16 adapter train; the base stays frozen.</li><li>Part of a shared control platform: the same harness is meant to host other control types (see roadmap below).</li></ul><h2 id="method">Method</h2>The adapter has one fusion point at the model input and trains two small parts.Conditioning. The base VAE encodes the skeleton pose map into a control latent, the same latent space as the noisy image, so the control stays spatially aligned with the generation.Fusion (<code>ControlEmbedder</code> + <code>ControlInitialLayer</code>). A zero-initialized <code>ControlEmbedder</code> (a patch projection on the control latent) produces control tokens that are added to the frozen base patch-embed output inside an overridden <code>ControlInitialLayer</code>. This is the only place the forward pass changes.

Pose agreement is scored by re-detecting keypoints on each generated output and comparing to the target skeleton (PCK@0.1 = fraction of keypoints within 10% of the pose bounding-box diagonal).<img src="https://huggingface.co/Claquasse/Anima-Control-Pose/resolve/main/samples/grid.png" alt="Base vs pose control on held-out poses" />Each row: the input reference, the DWPose skeleton extracted from it, base Anima at the same prompt and seed, then the pose-controlled output.

Fine detail (hands, faces) is also limited at this resolution.</li><li>Single input injection. Control is asserted once, at the input; at low strength the model may under-follow the pose.

The harness owns the frozen base, the adapter machinery, and the data/caching path; each control type plugs in by supplying a conditioning encoder and a fusion point. Planned v1 components:<ul><li>Pose v1: this preview, hardened for higher fidelity and reliable adherence.</li><li>IP-Adapter v1: image-prompt conditioning, to drive style and content from a reference image.</li><li>Identity v1: face-identity conditioning, to keep a subject's identity across generations.</li></ul>A pose detector trained specifically for Anima is also on the table. The skeletons here come from DWPose, a general detector built for photographs, so it is noisy on anime art. An Anima-native detector would give cleaner skeletons for both the training data and inference, which should directly improve how closely generations follow the target pose.<h2 id="license">License</h2>These weights are a derivative of the Anima base model (<code>circlestone-labs/Anima</code>) and inherit its terms: the CircleStone Labs Non-Commercial License, and — because Anima is itself a derivative of Cosmos-Predict2 — the <a target="_blank" rel="ugc" href="https://www.nvidia.com/en-us/agreements/enterprise-software/nvidia-open-model-license/">NVIDIA Open Model License</a>.The model weights are for non-commercial use only. Generated images (outputs) are not restricted by these terms and may be used commercially.
