OpenDM-format BF16 checkpoint for **DM05-mem** (32-slot history EEF).
Use with [OpenDM](https://github.com/dexmal/opendm) `playground/dm05_mem.py`.
See the [DM05 Inference Guide](https://github.com/dexmal/opendm/blob/main/docs/en/dm05_inference.md).

Weights: BF16 `model.safetensors`.

## Model Card

| Field | Value |
| --- | --- |
| Config | `playground/dm05_mem.py` |
| Env vars | `DM05_MEM_CHECKPOINT` |
| OpenDM `robot_type` | `ARX5` (playground default) |
| Control | EEF (`control_mode=eef`) |
| Cameras | Head / Left wrist / Right wrist |
| Native state / action | 7 / 7 (xyz+rpy in, xyz+axis-angle+gripper out) |
| Defaults | `action_horizon=50`, `is_history=true`, `speed=0.1`, `model_max_length=2048` |

## Use with OpenDM Inference

```bash
# From the OpenDM repository root.
hf download Dexmal/DM05-MEM \
  --local-dir ./checkpoints/DM05-MEM
pip install -e ".[fast-infer]"

script/dm05_launcher.sh \
  --exp playground/dm05_mem.py \
  --task inference \
  --model-config.model-name-or-path ./checkpoints/DM05-MEM \
  --inference-config.port 7891
```

Override with the env var used by the playground:

```bash
export DM05_MEM_CHECKPOINT=/path/to/DM05-MEM
python playground/dm05_mem.py
python playground/dm05_mem.py --inference-config.backend fast
```

## Runtime Profile

From `playground/dm05_mem.py`:

- `control_mode=eef`, `action_mode=absolute`, `speed=0.1`
- `is_history=true`, `max_history_images=32`
- attn: llm/action `sdpa`, vision `flash_attention_2`
- fast: prefix `2048`
