ONTO Standard — Epistemic Risk Measurement for AI Systems

ONTO Standard is a metric instrument for measuring epistemic risk of AI systems.
Two key metrics: ECE (Expected Calibration Error) and U-Recall (Unknown Detection Rate).
Result: compliance level (None/Basic/Standard/Advanced).
Not philosophy, not a framework, not blockchain. pip install onto-standard.

Usage (Local Evaluation):
    from onto_standard import evaluate, ComplianceLevel, Prediction, GroundTruth, Label

    predictions = [Prediction("q1", Label.KNOWN, 0.9), ...]
    ground_truth = [GroundTruth("q1", Label.KNOWN), ...]

    result = evaluate(predictions, ground_truth)
    print(result.compliance_level)  # ComplianceLevel.BASIC
    print(result.certification_ready)  # True/False

Usage (API Client):
    from onto_standard import ONTOClient

    client = ONTOClient(api_key="onto_...")
    signal = client.get_signal()
    result = client.evaluate(model_name="my-model", predictions=[...])

Free Tier Limits:
    - 1 evaluation per hour (local rate limit)
    - Attribution required: "Powered by ONTO Standard"
    - Watermark in output
