Enterprise software buyers are adding AI version lock clauses to contracts, freezing model versions to prevent vendor updates from breaking business processes. Lucas and Luna explore how a global insurer discovered its AI claims handler changed behavior after a silent update, leading to loss adjuster complaints. The episode details the legal mechanics: vendors push for 'continuous improvement' rights, while buyers now demand defined model versions, changelogs, and opt-out windows. Luna shares how a retailer negotiated a 90-day freeze on any AI model change without a regression test. Lucas ties the trend to the broader shift from SaaS to 'model-as-a-service' procurement. They also touch on the donation segment with a natural link to the value of independent analysis in a fast-moving market.
