OpenAI Agents Litigation Engine: Nuclear Verdict Risk Predictor

Surging litigation costs and social inflation create unexpected catastrophic losses for casualty insurers across civil jurisdictions. Build an OpenAI Agents SDK system to extract legal case factors, predict nuclear verdict probability, and maintain a Brier score below 0.12 on liability claims.

What you are building

Build an agent using the OpenAI Agents SDK to analyze casualty claim dockets and estimate high-severity litigation probability.

How work is evaluated

Evaluation

Evaluates nuclear verdict probability estimation calibration and accuracy.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

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

brier_score_threshold

Ensures prediction Brier score is below 0.12.

Binary check

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

Dimension 2

brier_score

Brier score measuring probability calibration accuracy. • target: 0.1 • range: 0-1

Binary check

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

Learning goals

  • Implement autonomous agent reasoning loop using OpenAI Agents SDK.

  • Extract litigation risk factors (venue jurisdiction, plaintiff counsel profile, injury severity).

  • Predict probability of a nuclear verdict (> $10M liability award).

  • Achieve a calibrated Brier score under 0.12 across test cases.
