Key features
- Precise Motion Transfer: Uses AI to map source motion onto target characters, preserving timing and movement nuances for realistic results.
- Full-Body Performance Support: Handles complete body motion transfer including limbs, torso, and overall posture to reproduce complex actions.
- Expression Mapping: Captures and transfers facial actions and expressions to enhance character believability and emotional range.
- Professional Control: Provides production-oriented controls to fine-tune and adjust transferred motion for shot-specific or stylistic needs.
- Precise motion transfer to characters
- Support for realistic full-body performance retargeting
- Facial expression and action transfer
- Professional controls for refining outputs
- Integration-friendly outputs suitable for animation pipelines
Best for
- Character Animation Production: Rapidly generate base animations for characters in film, TV, or game projects to accelerate animator workflows.
- Performance Transfer from Actors: Map live actor performances onto digital avatars for virtual production or cinematic scenes.
- Facial and Emotional Animation: Create expressive facial performances by transferring subtle expression data to character rigs.
- Iteration and Refinement: Use AI-transferred motion as a starting point for animators to quickly refine timing and poses to final quality.
- Prototype and Previsualization: Quickly populate scenes with realistic character motion for layout, blocking, and previs stages.
- Animating game characters using live or recorded performances
- Film and VFX character performance retargeting
- Virtual production and real-time character driving
- Generating expressive avatars for AR/VR experiences
- Accelerating character animation workflows in studios

Soup CLI
MePlay, Inc.
Open-source CLI that runs the whole LLM post-training stack — SFT, DPO, ORPO — on a 4GB laptop GPU.
Key features
- Whole Post-Training Stack: SFT, DPO, ORPO, SimPO, KTO, and more in one CLI.
- Low-VRAM Streaming: Fine-tune Llama-3.1-8B on a 4 GB GPU by streaming the base from RAM/NVMe.
- Auto-Configured Runs: Task, LR, epochs, and quantization derived from rules instead of grid search.
- Self-Healing Training: Detects and self-corrects reward hacking mid-run.
- One-Command Migration: `soup migrate` converts LLaMA-Factory, Axolotl, and Unsloth configs.
- Ship Gate: Every checkpoint is evaluated and either passes or is rejected before saving.
- Broad Ecosystem: Integrates with HuggingFace, Ollama, vLLM, DeepSpeed, Unsloth, ONNX, TensorRT, W&B.
- MLX + Apple Adapter: First-class Apple silicon support.
Best for
- Fine-tuning open-source LLMs on a consumer laptop GPU
- Post-training alignment (DPO/ORPO) without a rented A100
- Migrating existing LLaMA-Factory / Axolotl pipelines to a simpler workflow
- Producing evaluated, ship-gated checkpoints for internal deployment
- Researchers experimenting with 23 training methods without rewriting scripts
