Challenge

Real-Time Clearing Ledger Anomaly Guard with Pydantic AI & Qwen 3

High-frequency institutional clearing engines require microsecond-level ledger anomaly detection to prevent systemic counterparty risk during market volatility. Build a type-safe clearing telemetry engine using Pydantic AI and Qwen 3 to detect ledger discrepancies, validate margin compliance, and achieve 99% accuracy on simulated trade settlement datasets.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

pydantic_type_check

Ensures response object instantiates the target Pydantic class without validation error.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

clearing_anomaly_accuracy

Accuracy in distinguishing valid clears from anomalous trades. • target: 0.99 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
