About this project
Legal AI tasks are not one-size-fits-all. Extracting clauses from contracts requires different model capabilities than interpreting legal obligations or assessing compliance risks. LAMMR (Legal Adaptive Multi-Model Router) addresses this by dynamically routing each task to the most suitable language model, combining rule-based logic with a learned predictor. Every routing decision is logged and auditable – a requirement in legal deployments where transparency and reliability are non-negotiable. A task-aware evaluation layer scores extraction and reasoning outputs separately, preventing performance in one area from masking failures in the other. The system was validated on over 1,000 legal tasks and demonstrates significant improvements over single-model deployment. Accepted at HHAI 2026 (5th International Conference on Hybrid Human-Artificial Intelligence), Brussels, July 6–10, 2026.
