A user conducted a comparative test to evaluate the effectiveness of AI models for legal research, specifically comparing Anthropic's Fable model against Opus, Sonnet, and Haiku, as well as traditional legal research platforms like Westlaw and Lexis. The test involved a complex legal assignment concerning piercing the corporate veil of a Delaware LLC. The user found that Fable, particularly in its "high effort" setting, was the most capable AI model, identifying all relevant legal issues and providing accurate answers without hallucinations, comparable to the work of a human attorney. While Fable made a mistake in its "max effort" setting, the user concluded it is currently the best AI for legal research tasks. AI
IMPACT Fable's strong performance suggests specialized AI models can rival or exceed human capabilities in niche professional domains like legal research.
