# Foundry-VLA-1.7B-real
|
| 15 |
+
|
| 16 |
+
A 1.7B parameter vision-language-action model for bimanual robotic manipulation, part of the [VLA Foundry](https://github.com/TRI-ML/vla_foundry) collection. Trained on real-world manipulation data only.
|
| 17 |
+
|
| 18 |
+
## Model Description
|
| 19 |
+
|
| 20 |
+
- **Architecture:** Foundry-VLM-1.3B vision-language backbone + (condition on last 4 layers) flow-matching diffusion action head (24 layers, 1024 hidden dim, 16 heads)
|
| 21 |
+
- **Parameters:** 1.7B (non-embedding)
|
| 22 |
+
- **Action space:** 20-dim relative actions (bimanual xyz + 6D rotation + gripper)
|
| 23 |
+
- **Cameras:** 4 views (2 scene + 2 wrist)
|
| 24 |
+
- **Training data:** 102M samples from real-world bimanual manipulation tasks only
|
| 25 |
+
- **VLM backbone:** [Foundry-VLM-1.3B-200M](https://huggingface.co/TRI-ML/Foundry-VLM-1.3B-200M)
|
| 26 |
+
|

+
## Evaluation Results
|
| 28 |
+
|
| 29 |
+
Success rates on 16 seen tasks and 3 unseen tasks (200 rollouts per task):
|
| 30 |
+
|
| 31 |
+
| Simulator | Seen (16 tasks) | Unseen (3 tasks) |
|
| 32 |
+
|---|---|---|
|
| 33 |
+
| CS | 1.0% | 0.3% |
|
| 34 |
+
| OSS | 2.2% | 4.5% |
|
| 35 |
+
|
| 36 |
+
Note: This model was trained on real-world data only and does not transfer well to simulation.
