Examples
Worked examples
- Is an instance
OLMo from AI2 with full training data, code, intermediate checkpoints, and weights released.
- Is an instance
Pythia model suite with full reproducible training pipeline.
Counter-examples
Looks similar, but isn't
- Not an instance
An open-weights model with undisclosed training data (not OSAID-compliant).
- Not an instance
An API-only proprietary model.
Editorial commentary
OSAID v1.0 (2024) is the first formal articulation of what 'open source' means in an AI context, deliberately distinguished from 'open weights'. Many widely cited 'open' models do not meet the full OSAID criteria because their training data is not fully disclosed. The definition is expected to evolve; the criterion-based framing of this dictionary entry avoids tracking that evolution.
