Answer · confidence: partial
Who made the first rules limiting outside coders using a company's AI?
Research question: Who set the first published rules for how outside developers could use a company's AI system, and what limits did those rules impose?
The records do not show who published the first rules for outside developers, so this answer is partial. In 2020, OpenAI asked developer Jason Rohrer to bring his GPT-3 chatbot into line with its safety guidelines, but that was an enforcement request, not a published rule 1. The earliest dated published rules in the set are OpenAI's March 2023 usage policies, which allowed API integration into products on all major technology platforms and app stores, subject to use case restrictions 3. Those policies barred uses such as adult content, adult industries, and dating apps, and barred tailored financial advice without a qualified person's review and the diagnosis of health conditions or treatment instructions 57. Consumer-facing medical, financial, legal, and news uses had to disclose that AI was in use, and repeated or serious violations could lead to account suspension or termination 910. The newest fact in the set is dated March 23, 2026, from Google's Gemini terms, so the most recent evidence is about six months old as of October 2026 1214.
