This repository contains the official trained policies for The files are organized by task environment and training seed: The play.py script in the JoSE repository downloads a pretrained model and executes it in the corresponding environment, allowing agent behaviour to be visualized. The script is called from the repo root as follows: Seeds vary by hand and task. See the HuggingFace model directory to see which seeds are available for each task-hand combination.

Loading Example

Prerequisites: clone and install the JoSE repository.

The play.py script in the JoSE repository downloads a pretrained model and executes it in the corresponding environment, allowing agent behaviour to be visualized. The script is called from the repo root as follows:

uv run python play.py --hand <hand> --task <task> --seed <seed>
Argument Choices
--hand Adroit, MyoHand
--task BaodingBalls, DieReorient, KeyTurn, PenTwirl, Reorient8-sparse, Reorient100/Training
--seed 0, 1, 2, 3, 4, 5

Seeds vary by hand and task. See the HuggingFace model directory to see which seeds are available for each task-hand combination.

Logics-SWE-Qwen3.6-27B

Logics-MLLM

[2026.09.18] Released Logics-SWE-Qwen3.6-27B under the Apache-2.0 license. - The technical report is in preparation. A link will be added when available. Logics-SWE-Qwen3.6-27B is a 27B-parameter model developed for repository-level software engineering agents. Starting from the Qwen3.6-27B model used in our study, it combines category-aware expert development with multi-teacher on-policy distillation into a single deployment policy. Repository-level tasks require agents to navigate code, edit files, execute commands, inspect feedback, and iteratively repair their solutions. Our work starts from the category see-saw: aggregate progress during joint RL can conceal opposing changes across…

Djbob

PPO policies for a two-wheeled balancing robot (wheeled inverted pendulum), trained in MuJoCo Warp via mjlab with rslrl and cross-checked against a PyBullet oracle. Each policy is an ONNX file laid out as /model.onnx. The run name is the training recipe; results for each are in the source repo's TRAININGLOG.md. Older entries are raw rslrl.pt checkpoints (below). Several observation interfaces live in this repo. The sk runs are the runs are interface-ablation artifacts, and they differ from each other as well as from sk: ablcombo is 10 inputs wide, while ablnolpfjerk1 keeps all 40 and changes what one channel means. Read the width and the filter constants from each file's metadata rather…

ganglion-haltere-cursor

Artem Skulimovskiy

Two checkpoints of the Haltere fly-brain connectome (a 30,000-neuron recurrent network with the connectome's structure and signs, flight-trained) with a linear motor readout that turns the network's motor-neuron rates into a cursor or view velocity, trained by imitation of a proportional controller in Ganglion, the reflex layer that runs them against live applications at 100 Hz. The report-.json files beside them are the training and suite reports they were selected from. Everything here was measured on one machine (RTX 4090, Windows 11); the numbers are the suite's and the live harness's, with their caveats, and are documented in full in the repository's TRAINING.md and HALFLIFE.md.
