rldx2_rldximg_robotwin_b128_60k is an open-weight model for robotics from KOO, MYUNGKYU. It has 6.9B parameters. At 16-bit it needs about 16.6 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index.
Vanilla baseline for the RLDX-2 project: RoboTwin 2.0 leaderboard co-train setting (50 tasks x 50 democlean episodes, Aloha-AgileX, official LeRobot export).
What it takes to serve rldx2_rldximg_robotwin_b128_60k (6.9B parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

| Precision | Weights in memory |
|---|---|
| As published | 55.3 GB |
| 16-bit | 13.8 GB |
| 8-bit | 6.9 GB |
| 4-bit | 3.5 GB |
Weights only, from the published parameter count; the key-value cache and runtime add to this.
About 16.6 GB at 16-bit and 4.1 GB at 4-bit: the weights (6.9B parameters) plus a working margin. A long context needs more.
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.

FLUX 3 Action (flux3) is Black Forest Labs' video-action model: the FLUX.3 video trunk with an action modality that is denoised jointly with the next video frames, finetuned per robot embodiment with fresh action heads. This policy has been trained and pushed to the Hub using LeRobot. Learn how to train and run it in the LeRobot flux3 guide, or browse the full documentation. The policy consumes these observation features and produces these action features. Inputs Outputs New to LeRobot? These guides cover the full workflow: - Install LeRobot — set up the lerobot package. - Hardware setup — assemble, wire, and calibrate your robot and cameras. - Record data & train a policy — the end-to-end…
OpenVLA 7B (openvla-7b) is an open vision-language-action model trained on 970K robot manipulation episodes from the Open X-Embodiment dataset. The model takes language instructions and camera images as input and generates robot actions. It supports controlling multiple robots out-of-the-box, and can be quickly adapted for new robot domains via (parameter-efficient) fine-tuning. All OpenVLA checkpoints, as well as our training codebase are released under an MIT License. For full details, please read our paper and see our project page. OpenVLA models take a language instruction and a camera image of a robot workspace as input, and predict (normalized) robot actions consisting of 7-DoF…
This repository contains the OpenVLA-OFT checkpoint for LIBERO-Spatial, as described in Fine-Tuning Vision-Language-Action Models: Optimizing Speed and Success. OpenVLA-OFT significantly improves upon the base OpenVLA model by incorporating optimized fine-tuning techniques.
