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.
What you are building
The core problem, expected build, and operating context for this challenge.
Build a type-safe, validated clearing house anomaly detector using Pydantic AI and the Qwen 3 open model runtime.
How work is evaluated
Evaluates trade settlement anomaly detection accuracy and Pydantic schema validation integrity.
Shared data for this challenge
Review public datasets and any private uploads tied to your build.
How submissions are scored
These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.
pydantic_type_check
Ensures response object instantiates the target Pydantic class without validation error.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
clearing_anomaly_accuracy
Accuracy in distinguishing valid clears from anomalous trades. • target: 0.99 • range: 0-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
