b'maintain and update the underlying model architecture, while legal technology vendors integrate those models into products designed for lawyers.modelsOneanalogywefindhelpfulisthatofmakes andintheautomotiveindustry.Automobilesare generally classified by their make, model, and sometimes a trim or body style. For example, Honda (themake ) produces the Accord (themodel ) which comes in different versions with varying features. 19GAI producers and their models can likewise be conceptualized this way, as depicted in Table 1 below. As you can see, many model producers use their own model to power a native application that is licensed Table 1: Table showing major GAI companies, models, and core applicationsdirectlybythatprovider.Forexample,OpenAIprovidestheGPTbrandedmodelforthirdpartiesto integrate into their applications, but OpenAI also uses that same model to directly provide various versions of ChatGPT. 20 Side Note: Generative Versus Extractive AI Throughout this Guide, we use the termgenerativeto refer to the core architecture that underlies almost everymodernartificialintelligenceapplicationusedwithinthepracticeoflaw.Thetransformeris consideredgenerativebecause it is designed to produce outputs in response to inputs. In some cases, those outputstaketheformofnewcontent(suchastextorimages);inothercases,theoutputsmaybe reformulated queries or summaries that retrieve material from an external data source. However, you may encounter AI discussions that divide AI systems into two basic types:generativeandextractive . We do not view this as a significant distinction, because the termsgenerativeandextractiveare simply descriptions of two functions that the same underlying transformer model might be used to produce. 21 Accordingly, when the termsGenerative Artificial IntelligenceandGAIare used throughout this Guide, we mean for those terms to encompass systems which perform bothgenerativeandextractivefunctions. In short, its important for lawyers to understand the basic GAI risk assessment that applies to all GAI tools, whether they are acting in agenerativeorextractivecapacity. 19Honda Accord Family, Sedans and Hybrids , Honda, https://automobiles.honda.com/accord (last visited Sept. 11, 2025).Independent Service Auditors SOC 3 Report for the API and ChatGPT Business Product 20 See, e.g. , Schellman & Co., LLC, (Aug. 7, 2025), https://trust.openai.com.Se rvic,e Ans Sdyrsteewm F froere tdh ee tP aelr.,i od of January 1, 2025 to June 30, 2025(Manning Publications 2025) (explaining 21that, historically, extractive AI referred to classifier-based systems, but modern transformer-based systems can peSrefoerm both extractive andE fgfeecnteivrea tCivoen vfuernscattioionnsa wl AitIh: iCnh tahteb ostasm thea atr Wchoitrekcture);See also , Trey Grainger et al.,AI-Powered Search(OReilly Media 2025) (describing how GAI models are used in various search contexts, including extractive, abstractive, and generative search modes).Page | 6'
