b'Key Takeaways Taking all this together, the key things you should understand from this section are:When artificial intelligence is used within the practice of law, it is almost universally focused on the2017 technology breakthrough called atransformer , which is the foundation for Generative Artificial Intelligence. make and modelTransformers can be understood using a analogy, whereby AI-focused companies(such as OpenAI and Anthropic) produce various transformer models (such as GPT and Claude).WhenlawyersconsiderwhetheraparticularGAItoolisappropriateforprocessingvarioustypesof information (including confidential or sensitive client information), its important to understand that this information is being transmitted to, and processed inside, a particular transformer model. Thus, lawyers should know who produces that model, and what privacy and security safeguards are in place.

How to Choose an Appropriate GAI Tool LawyersdonotneedtobecomeAIexpertstouseGAItoolseffectively,buttheydoneeda structured approach to evaluating the many tools that are available, classifying the type of data these tools will process, and communicating with clients about how GAI may be used to work on their matters.This section outlines a practical, step-by-step framework that can be adapted to most practice settings. We do not intend this to be mandatory, but we encourage lawyers to adapt this framework to their own practices. The framework is offered as a nonbinding example which, if adapted to a lawyers specific circumstances, may help document the safeguards required under Illinois Rule 1.6 and support a showing of reasonableness. d It should be cle the Information to Be Prvery setool on the market is appropriate for every type of data Step 1: Classifyar at this point that not eocesGAIlawyersmaywishtoprocess.Therefore,whenselectingaGAItool,lawyersmustfirstclarifywhat information they intend to use that system to process. We suggest the following classifications, presented in order of lowest to highest risk: (a)General InformationIf information is entirely unrelated to any matter the lawyer has undertaken professionally, and is otherwise not subject to any confidentiality protections, we consider it General Information and assign the lowest level of risk. Examples include using GAI tools for internal technology troubleshooting, generating forms and checklists, drafting marketing content or assisting in writing blog articles. Page | 7'
