dynamic-vla-r1lite-bread-bag-100k

by SY 2sin0/dynamic-vla-r1lite-bread-bag-100k

dynamic-vla-r1lite-bread-bag-100k is an open-weight model for robotics from SY, released under other. It has 430M parameters. At 16-bit it needs about 1 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index.

DynamicVLA fine-tuned from hzxie/dynamic-vla-DOM for the R1Lite task pick up the bread bag. This is the completed 100,000-step checkpoint, with both arms represented as end-effector poses and gripper states. Use the adapted DynamicVLA code.

Model Card

DynamicVLA fine-tuned from hzxie/dynamic-vla-DOM for the R1Lite task pick up the bread bag. This is the completed 100,000-step checkpoint, with both arms represented as end-effector poses and gripper states. Use the adapted DynamicVLA code. Both this model repository and the linked source-code repository are public. The upstream DOM simulation inference script assumes a different robot/action layout; use the R1Lite deployment server described below. - model.safetensors: complete policy weights, including fine-tuned normalization buffers. - config.json: model architecture and action representation. - normalization.json: training-only statistics, split IDs, vector layout, and dataset hashes.…

Questions About dynamic-vla-r1lite-bread-bag-100k

How much GPU memory does dynamic-vla-r1lite-bread-bag-100k need?

About 1 GB at 16-bit and 0.3 GB at 4-bit: the weights (430M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run dynamic-vla-r1lite-bread-bag-100k on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

What license is dynamic-vla-r1lite-bread-bag-100k released under?

other, as its publisher declares it. Read the license text before commercial use.

Diffusion Policy treats visuomotor control as a generative diffusion process, producing smooth, multi-step action trajectories that excel at contact-rich manipulation. This policy has been trained and pushed to the Hub using LeRobot. See the full documentation at LeRobot Docs. For a complete walkthrough, see the training guide. Below is the short version on how to train and run inference/eval: Writes checkpoints to outputs/train/ /checkpoints/. Prefix the dataset repo with eval\ and supply --policy.path pointing to a local or hub checkpoint.
