# MiniVLA 1B VQ Trained on Bridge V2 (Prismatic-Compatible Version)
|
16 |
+
|
17 |
+
<b>This checkpoint is in a format that is compatible with the training script from the original [Prismatic VLMs project codebase](https://github.com/TRI-ML/prismatic-vlms), which the OpenVLA
|
18 |
+
team built on top of to develop the OpenVLA model.</b>
|
19 |
+
|
20 |
+
This Prismatic-compatible checkpoint may be useful if you wish to <b>fully fine-tune</b> MiniVLA (all 1 billion parameters) via native PyTorch Fully
|
21 |
+
Sharded Data Parallel (FSDP) using the Prismatic VLMs training script. If you instead wish to do Parameter-Efficient Fine-Tuning via LoRA, you
|
22 |
+
can use the MiniVLA checkpoint linked above, which is compatible with the Hugging Face `transformers` library. We recommend fine-tuning via LoRA if
|
23 |
+
you do not have sufficient compute to fully fine-tune a 1B-parameter model (e.g., multiple A100/H100 GPUs).
|
24 |
+
|
25 |
+
## Usage Instructions
|
26 |
+
|
27 |
+
See the [MiniVLA GitHub README](https://github.com/Stanford-ILIAD/openvla-mini/blob/main/README.md) for instructions on how to use this checkpoint for full fine-tuning.
