## Questions

**Which AI model is best for legal research?**

BenchLM does not rank models for this job from general language-model scores. A general model score is not a legal-work qualification. This task needs jurisdiction-specific and document-specific evaluation. Use the specialist evidence pages instead.

**How does BenchLM pick the best ai model for legal research?**

The page runs the LLM Selector with fixed answers: a builder choosing by accuracy, hosted processing allowed. The selector uses no general score for this job, filters by the stated constraints, and orders by that evidence. It never adds a hidden fit score or a bonus for open weights or reasoning style.

**Can I change the constraints?**

Yes. Every link under "Refine" opens the selector with one answer changed, and the address carries the answers so a result can be shared or reopened against the current dataset.
