# 4D-R1

LoRA adapters for 4D-R1, a reinforcement post-training framework for motion control and efficient video generation built on VerseCrafter.

| Directory | Paper model |
|---|---|
| `4D-R1-GRPO` | GRPO |
| `4D-R1-NFT` | NFT |
| `4D-R1-GRPO-MP` | GRPO (mixed-precision) |
| `4D-R1-NFT-MP` | NFT (mixed-precision) |

Each directory contains `adapter_model.safetensors` and `adapter_config.json`. The adapters use LoRA rank 16 on the q, k, v, and o projections.

Inference requires the VerseCrafter base model, its companion components, and the compatible 4D-R1 inference implementation.

MP denotes mixed-precision training.

The corresponding paper rows are GRPO, NFT, GRPO (mixed-precision), and NFT (mixed-precision).

`SHA256SUMS` provides checksums for the adapter weights and configuration files.
