rldx2_pi05_robodojo_vanilla_b128_60k

by KOO, MYUNGKYU Myungkyu/rldx2_pi05_robodojo_vanilla_b128_60k

rldx2_pi05_robodojo_vanilla_b128_60k is an open-weight model for robotics from KOO, MYUNGKYU. It has 4.1B parameters. At 16-bit it needs about 9.9 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: RoboDojo Sim co-train setting (35 tasks x 100 episodes, dual ARX X5, official LeRobot export).

Final checkpoint after 60,000 optimization steps. This is a trained policy, not an evaluation result. Policy weights, policy configuration, preprocessing/postprocessing and normalization states are at the repository root. Training resume files are in trainingstate/. Host-specific paths were removed from JSON metadata; supply local dataset/output paths when resuming. The tokenizer reference points to google/paligemma-3b-pt-224 (training revision 35e4f46485b4d07967e7e9935bc3786aad50687c). For subtask models, supply the corresponding per-frame subtask as the policy task text. For 3-view models also supply the dataset-defined keyframe image. No real-robot evaluation metrics are claimed here.…
