Multi-Model Strategy in Legal

A directional estimate suggests firms rarely rely on a single model once they scale. Solo practitioners average an estimated 1.4 models, while Big Law firms (50+ lawyers) run closer to 3.5, with in-house teams in between at 2.6. The pattern points to multi-model stacks as a function of size and risk exposure, not preference: larger firms appear to route different work (drafting, research, review) to different models rather than standardizing on one, likely to balance accuracy, cost, and data-privacy tradeoffs across practice areas. For smaller firms, this scenario implies less redundancy and more dependence on whichever single model they've adopted.
