ChatGPT and Generative AI Legal Research Guide

What is Claude 3?

Claude 3 Opus is the most advanced model in Anthropic's Claude 3 family, setting new benchmarks across a wide range of cognitive tasks.

Claude 3 Opus is currently the best AI system for legal research, according to Anthropic. It is available to Claude Pro subscribers for $20 per month. Anthropic also provides free models in the Claude 3 family for general use.

How Does It Work?

• Claude 3 Opus is a large language model that generates human-like responses by predicting the next word in a sequence based on its training data.
• When prompted with a question or task, it leverages its extensive knowledge to generate the most relevant and coherent response.

Limitations

• The training data for Claude 3 Opus only extends to August 2023, so it may not include the most recent information or materials.
• As with all generative AI systems, Claude 3 Opus can produce inaccurate or hallucinated information, requiring independent verification and fact-checking.
• While highly capable, it is an assistive tool and not a replacement for human expertise.

Claude 3, the latest AI model from Anthropic, has demonstrated impressive capabilities in legal research and memo writing. In a recent test, a legal research instructor provided Claude 3 with a fact pattern and asked it to analyze the issue, list relevant Texas statutes and cases, and generate a 1,500-word legal memorandum. Claude 3 performed remarkably well, especially when compared to other AI systems like ChatGPT-3.5, Lexis+ AI, and Microsoft Copilot.
