OneOpen ML Studio

Open-source, local-first ML data platform
From raw data → annotation → validated versions → training-ready datasets → models.

Product definition

An open-source, local-first and self-hosted collaborative machine-learning data platform for preparing, annotating, validating, versioning, training and managing ML datasets and models.

Core workflow (target platform):

Raw Data → Profiling → Annotation → Review → Quality Validation
→ Transformation → Dataset Version → Training Readiness
→ Model Training → Experiment Comparison → Model Registry → Active Learning

Differentiation:

Multi-modal annotation
+ Training-ready dataset generation
+ Reproducible versioning
+ Multi-user collaboration
+ Shared GPU training
+ Framework-neutral adapters
+ Local-first deployment

Computer vision, text, tabular, audio, video, and LLM dataset workflows ship in this package. Visual pipelines, Team/Enterprise setup, and org→workspace→project hierarchy are included. See the docs roadmap for planned SSO handshake and shared GPU scheduling.

Install

pip install oneopen-ml-studio

With extras:

pip install "oneopen-ml-studio[yolo]"       # Ultralytics Label Assist + training
pip install "oneopen-ml-studio[libreyolo]"  # LibreYOLO backend
pip install "oneopen-ml-studio[sam]"        # SAM deps (torch); install segment-anything separately
pip install "oneopen-ml-studio[all]"

From source:

git clone https://github.com/1-OpenSource/OneOpen-ML-Studio.git
cd OneOpen-ML-Studio
pip install -e ".[yolo]"

Quick start (local mode)

oneopen init
oneopen start          # alias: oneopen serve → http://127.0.0.1:8765

Or: python -m oneopen_ml_studio start

No cloud account. No mandatory registration. Data stays under ~/.oneopen (or ONEOPEN_DATA_DIR).

What works today
