Key Insights from the Latest Legal AI Research
A recent study by the British law firm Linklaters reveals that artificial intelligence (AI) tools have significantly improved in answering legal questions. However, they still fall short of matching the competence of even a junior lawyer.
Research Overview
- Testing AI in Legal Work: Linklaters tested AI chatbots by asking them 50 complex questions about English law.
- AI Performance Over Time: OpenAI’s older GPT-2 model from 2019 performed poorly, but the latest o1 model (December 2024) showed notable progress.
- Still Below Human Level: Despite improvements, none of the AI models matched the expertise of a mid-level lawyer with two years of experience.
Key Findings
- Improved but Imperfect: Modern AI models provided better answers than their predecessors but still made mistakes, omitted key details, and sometimes generated false citations.
- Potential Uses:
- Drafting initial versions of legal documents.
- Cross-checking legal research for accuracy.
- Risks Identified:
- Over-reliance on AI can lead to errors if lawyers lack a clear understanding of legal principles.
Industry Concerns and Responses
- AI as a Tool, Not a Replacement: Experts emphasize that AI can assist lawyers but cannot replace their judgment and client relationships.
- Law Firms Taking Action:
- Hill Dickinson, another international law firm, restricted access to AI tools due to increased usage by employees.
- Global AI Regulation Debate:
- Countries differ on AI safety and innovation. The US and UK recently declined to sign an international AI safety agreement.
Future Outlook
- Steady Progress with Limits: While AI tools are becoming more capable, experts question whether future models will overcome their current limitations.
- Human Expertise Remains Key: Legal professionals believe that personal client interactions will continue to be essential, regardless of AI advancements.
Conclusion
AI is transforming legal research but is far from replacing lawyers. Firms should embrace AI as a supportive tool while maintaining expert human oversight.
