KIMODO - Kinematic Motion Diffusion

KIMODO is integrated as an motius runtime wrapper around a vendored copy of NVIDIA's official Python runtime under motius.models.motion.kimodo._vendor. Unlike the T2M-only baselines, the KIMODO pipeline is multi-task: the same bundle covers plain text generation and KIMODO's kinematic-control interfaces.

Implementation status: the artifact inference path is now ref_repo-free. KIMODOBundle imports the vendored runtime from the motius package. The SOMA-RP artifact packages the checkpoint snapshot and local text encoders; the G1 artifacts package their checkpoint snapshots and resolve the shared KIMODO text encoders from the SOMA-RP artifact on first model load.

Item	Value
Bundle / Pipeline	`KIMODOBundle` / `KIMODOPipeline`
Processed HF artifacts	`[SOMA-RP](https://huggingface.co/ZeyuLing/Motius-KIMODO-SOMA-RP)`, `[G1-RP](https://huggingface.co/ZeyuLing/Motius-KIMODO-G1-RP)`, `[G1-SEED](https://huggingface.co/ZeyuLing/Motius-KIMODO-G1-SEED)`, `[SMPLX-RP](https://huggingface.co/ZeyuLing/Motius-KIMODO-SMPLX-RP)` (private / license review)
Default model	`Kimodo-SOMA-RP-v1`
Runtime implementation	vendored under `motius.models.motion.kimodo._vendor.kimodo`
Supported skeletons	SOMA, Unitree G1, SMPL-X
Text encoder	LLM2Vec / Meta-Llama-3 local text encoder; stored in SOMA-RP and shared by G1 artifacts
SMPL mesh bridge	`motius.motion.retarget.KIMODOSOMAToSMPLRetargeter`

Weights

The SOMA-RP model-zoo artifact is self-contained, including the KIMODO checkpoint snapshot and text-encoder files needed by KIMODO's local encoder. The G1 artifacts store their own KIMODO checkpoint snapshots and point text_encoders_repo at the SOMA-RP artifact to avoid duplicating the same 16GB LLM2Vec / Meta-Llama tree in every KIMODO repository.

Variant	Processed Hugging Face artifact	Native skeleton	Status
SOMA-RP	`[ZeyuLing/Motius-KIMODO-SOMA-RP](https://huggingface.co/ZeyuLing/Motius-KIMODO-SOMA-RP)`	SOMA	packaged for motius, T2M visual path checked; private pending license review
G1-RP	`[ZeyuLing/Motius-KIMODO-G1-RP](https://huggingface.co/ZeyuLing/Motius-KIMODO-G1-RP)`	Unitree G1	packaged for motius; reuses shared text encoders from SOMA-RP
G1-SEED	`[ZeyuLing/Motius-KIMODO-G1-SEED](https://huggingface.co/ZeyuLing/Motius-KIMODO-G1-SEED)`	Unitree G1	packaged for motius; reuses shared text encoders from SOMA-RP
SMPLX-RP	`[ZeyuLing/Motius-KIMODO-SMPLX-RP](https://huggingface.co/ZeyuLing/Motius-KIMODO-SMPLX-RP)`	SMPL-X	packaged for motius; reuses shared text encoders from SOMA-RP

Because the KIMODO artifacts depend on third-party text-encoder weights, their redistribution status follows the upstream KIMODO, LLM2Vec, and Meta Llama licenses. The uploaded motius repos are kept private until those redistribution terms are reviewed. The Meta-Llama text encoder is stored once in standard Transformers safetensors shards inside the SOMA-RP artifact; duplicate upstream original/*.pth exports are intentionally omitted.

Loading

Load from Hugging Face with the same from_pretrained style used by the other motius model-zoo entries:

python

from motius.pipelines.motion.kimodo_pipeline import KIMODOPipeline

pipe = KIMODOPipeline.from_pretrained(
    "ZeyuLing/Motius-KIMODO-SOMA-RP",
    device="cuda",
)
out = pipe.text_to_motion("a person walks forward.", num_frames=150)

Use the matching repo id for Unitree G1 or SMPL-X variants:

python

pipe = KIMODOPipeline.from_pretrained(
    "ZeyuLing/Motius-KIMODO-G1-RP",  # or motius-kimodo-g1-seed
    device="cuda",
)
out = pipe.text_to_motion("a humanoid robot walks forward.", num_frames=150)

python

pipe = KIMODOPipeline.from_pretrained(
    "ZeyuLing/Motius-KIMODO-SMPLX-RP",
    device="cuda",
)
out = pipe.text_to_motion("a person walks forward.", num_frames=150)

For G1 and SMPLX artifacts, KIMODOBundle.from_pretrained resolves the shared text_encoders/ tree from ZeyuLing/Motius-KIMODO-SOMA-RP when the model is loaded. Since these repos are private during license review, run with an authenticated Hugging Face token that can read the KIMODO motius repos.

The lower-level bundle is still available when you need direct access to KIMODO runtime paths:

python

from motius.models.motion.kimodo import KIMODOBundle
from motius.pipelines.motion.kimodo_pipeline import KIMODOPipeline

bundle = KIMODOBundle.from_pretrained(
    "ZeyuLing/Motius-KIMODO-SOMA-RP",
    device="cuda",
)
pipe = KIMODOPipeline(bundle)

For environments that need an explicit local snapshot:

python

from huggingface_hub import snapshot_download
from motius.models.motion.kimodo import KIMODOBundle

path = snapshot_download("ZeyuLing/Motius-KIMODO-SOMA-RP")
bundle = KIMODOBundle.from_pretrained(path, device="cuda")

Local construction from official NVIDIA checkpoint folders is still available:

python

from motius.models.motion.kimodo import KIMODOBundle

bundle = KIMODOBundle.from_pretrained(
    "Kimodo-SOMA-RP-v1",
    device="cuda",
    text_encoder_mode="local",
    checkpoint_dir="checkpoints/kimodo/local_models",
    text_encoders_dir="checkpoints/kimodo/text_encoders",
)

Supported Tasks

The wrapper exposes the task surface KIMODO itself supports:

Task	Pipeline API	KIMODO control
Text-to-motion	`text_to_motion()` / `__call__`	prompt only
Multi-prompt motion	`multi_prompt()`	segment stitching with transition frames
Full-body keyframes	`fullbody_keyframe_constraint()` + `constrained_motion()`	`FullBodyConstraintSet`
End-effector control	`end_effector_constraint()` / hand-foot helpers	`EndEffectorConstraintSet`
2D root path / waypoints	`root2d_constraint()` + `constrained_motion()`	`Root2DConstraintSet`
Saved KIMODO demo constraints	`constraints_from_json()` + `constrained_motion()`	official constraint JSON

Examples:

python

# Multi-prompt stitching.
out = pipe.multi_prompt(
    ["a person walks forward.", "the person turns left."],
    [90, 90],
)

# Constraint JSON produced by the official KIMODO demos.
constraints = pipe.constraints_from_json("constraints.json", device="cuda")
out = pipe.constrained_motion(
    "a person follows the specified path.",
    num_frames=180,
    constraints=constraints,
)

# Programmatic 2D root waypoints.
root2d = pipe.root2d_constraint(
    frame_indices=[0, 60, 120],
    smooth_root_2d=[[0.0, 0.0], [0.8, 0.1], [1.5, 0.6]],
    device="cuda",
)
out = pipe.constrained_motion(
    "a person walks along a curved path.",
    num_frames=150,
    constraints=[root2d],
)

Retargeting To SMPL

For mesh inspection and HumanML3D-style evaluation, retarget KIMODO SOMA output through the rotation-aware SOMA-to-SMPL operator:

python

from motius.motion.retarget import KIMODOSOMAToSMPLRetargeter

retargeter = KIMODOSOMAToSMPLRetargeter(device="cuda")
smpl = retargeter.retarget_file("kimodo_debug_npz/000000.npz")
motion_135 = smpl["motion_135"]

The debug NPZ must contain KIMODO global_rot_mats. Position-only IK is a fallback for diagnostics and should not be used as the mesh-quality path.

Artifact Format

KIMODOBundle.save_pretrained() stores a complete runtime artifact:

text

kimodo_config.json
model_index.json
README.md
kimodo_checkpoint/Kimodo-SOMA-RP-v1/
text_encoders/

G1 and SMPLX artifacts use the same format but omit text_encoders/ locally:

text

kimodo_config.json
model_index.json
README.md
kimodo_checkpoint/Kimodo-G1-RP-v1/

KIMODOBundle.from_pretrained(path_or_repo) resolves the artifact-local kimodo_checkpoint/ and text_encoders/ directories into KIMODO's CHECKPOINT_DIR and TEXT_ENCODERS_DIR environment hooks before calling the official loader.

Package the default SOMA-RP model:

bash

python3 scripts/eval/convert_kimodo_checkpoint.py \
  --model_name Kimodo-SOMA-RP-v1 \
  --checkpoint_dir checkpoints/kimodo/local_models \
  --text_encoders_dir checkpoints/kimodo/text_encoders \
  --out_dir checkpoints/kimodo/motius_soma_rp \
  --verify

Package a G1 checkpoint from a local Hugging Face snapshot:

bash

python3 scripts/eval/convert_kimodo_checkpoint.py \
  --model_name Kimodo-G1-RP-v1 \
  --checkpoint_source checkpoints/kimodo/hub/models--nvidia--Kimodo-G1-RP-v1/snapshots/<sha> \
  --out_dir checkpoints/kimodo/motius_g1_rp \
  --no_text_encoder \
  --text_encoders_repo ZeyuLing/Motius-KIMODO-SOMA-RP \
  --copy_mode hardlink \
  --verify

Evaluation Status

Current status is intentionally split by task. The trusted HumanML3D T2M numbers below are from the SMPL-X-RP motius artifact, exported through the SMPL-X/SOMA-to-SMPL bridge and then scored with the persisted motius evaluators.

HumanML3D T2M Metrics (SMPL-X-RP, 2026-06-16)

Prediction/evaluation root: outputs/evaluation/kimodo_smplx_hml3d_smpl_ms272_v100x1_20260616.

Evaluator	Samples	FID ↓	R-Precision Top-1 / 2 / 3 ↑	Diversity →	MM-Dist ↓	Metric JSON
HumanML3D-263	2,478	1.8425	0.3135 / 0.4818 / 0.5925	9.1488	4.2810	`metrics/verify_hml263.json`
MotionStreamer-272	7,392	143.9169	0.3225 / 0.4601 / 0.5413	25.3156	21.7065	`metrics/verify_ms272.json`

The MotionStreamer-272 score uses the explicit KIMODO SMPL-X output -> SMPL motion_135 -> MotionStreamer-272 conversion chain. The GT(real) sanity row in the same run matches the persisted MotionStreamer evaluator contract (R@1=0.706, Diversity≈27.36, MM-Dist≈15.01), so these numbers are suitable for the current model card.

Reproduce the run with the Taiji submit helper:

bash

python3 scripts/submit/submit_kimodo_hml3d_smpl_ms272_taiji.py \

Area	Status
T2M SMPLX-RP	generated with the motius artifact, retargeted to SMPL, and scored with persisted evaluators
HumanML3D / MS272 metrics	trusted for SMPLX-RP run above; always copy future values from generated JSON files, not by hand
Multi-prompt / root path / keyframe / inbetween controls	API-supported in `KIMODOPipeline`; visualization must follow the task protocol manifest
End-effector controls	API-supported; visualization must render exported end-effector target points
Body-part control	unsupported for KIMODO; do not report forced subset constraints as a valid KIMODO task
G1-RP / G1-SEED	packaged as motius artifacts; runtime wrapper supports the native Unitree G1 skeleton
SMPLX-RP	packaged as an motius artifact; runtime wrapper supports the native SMPL-X skeleton

Visualization Protocol

KIMODO visualization is defined by reusable motius motion protocols, not by a one-off web page. The task/panel/frame contracts live in motius.motion.visualization.kimodo and motius.motion.visualization.protocol; the detailed condition families are documented in docs/motion/kimodo_visualization_protocols.md.

KIMODO is not a single T2M viewer case. Each supported task must expose the generated motion plus the task condition that the model was asked to satisfy. The current manifest layout is:

text

outputs/evaluation/<kimodo-viewer-root>/
  _manifest.json              # protocol rows from motius.motion.visualization
  _captions.json
  gt/<case>.npz               # same-timeline reference / condition-source SMPL motion
  condition_smpl/<case>.npz   # generated-timeline condition source, visible only on constrained frames
  kimodo_smpl/<case>.npz      # generated KIMODO retargeted to SMPL
  kimodo_soma/<case>.npz      # generated native SOMA mesh

_manifest.json includes frame_semantics, condition_overlays, panel_visible_ranges, missing_panels, and diagnostics. Missing panels are source/export limitations, not UI bugs. A gt panel is only valid when the reference motion is finite, nonzero, and on the same frame timeline as the generated motion. For transition/prepend tasks, use condition_smpl plus panel_visible_ranges.condition_smpl instead of fabricating full-timeline GT.

Run the viewer:

bash

PYTHONPATH=$PWD HFTRAINER_SKIP_AUTOREGISTER=1 \
python3 motion_annot_web/m2m_eval_viewer/retarget_smpl_app.py \
  --host 0.0.0.0 --port 8216 \

Task protocols:

Task	Condition shown in viewer	Generated output shown
Text-to-motion	text prompt	full generated motion
Full-body keyframes	exact keyframe indices from `keyframe_indices`	generated inter-keyframe motion
Inbetween endpoints	first and last frames	generated middle frames
Transition stitching	`condition_smpl` on A-tail/B-head ranges from `layout_json`; panel hidden during the generated transition	generated transition in `kimodo_soma` and `kimodo_smpl`
Prepend start pose	`condition_smpl` on target start pose and conditioned motion-A prefix; panel hidden during the generated prepend transition	generated prepend transition in `kimodo_soma` and `kimodo_smpl`
2D root path	`condition_overlays.root_trajectory` rendered only on the primary generated SMPL panel as one clean XZ path rail, start/end dots, a current-frame cursor, and one top-down XZ inset; generated body color remains generated output	generated body motion following the path
Constraint JSON	sparse saved KIMODO constraints, shown as every-30-frame markers when metadata is sparse	generated constrained motion
Body-part control	not shown; KIMODO has no native arbitrary body-part mask task	unsupported
Multi-prompt / local edit	segment prompt or edit mask	stitched / edited motion
Style edit	style instruction	style-transferred motion
End-effector control	`condition_overlays.joint_targets` rendered only on the primary generated SMPL panel; each frame shows only its active target points as compact colored anchors with a vertical locator line and floor ring	generated motion satisfying sparse targets

Condition frames are markers or overlays on the generated sequence, not a separate stream of motion. If the mesh visibly jumps around a keyframe marker, that is not an expected viewer-side transition. Check diagnostics.continuity in the manifest and then debug the KIMODO constraint / retarget export for that sample.

The viewer consumes _manifest.json instead of guessing from directory names. Each panel has an explicit role (reference, generated, generated_native), and each case has frame_semantics so discrete keyframes/endpoints and continuous-control tasks are displayed differently.

Relevant scripts:

scripts/submit/submit_kimodo_t2m_eval.py keeps the older T2M submission entry point.
scripts/kimodo/run_kimodo_all_tasks.py and tools/run_kimodo_all_tasks.py cover the broader KIMODO task family.
scripts/eval/run_kimodo_tp2m_table2.sh covers prefix-pose + text generation.
