In addition to its standalone products, OpenAI has launched APIs for programmers to use their models - at astoundingly cheap rates. Some people are saying that it makes more sense to just use OpenAI's tools than to build your own. Others are wary of becoming dependent on a loss leader, so they want to develop internal tools that can replicate OpenAI's capabilities.
(c) Restrictions. You may not (i) use the Services in a way that infringes, misappropriates or violates any person’s rights; (ii) reverse assemble, reverse compile, decompile, translate or otherwise attempt to discover the source code or underlying components of models, algorithms, and systems of the Services (except to the extent such restrictions are contrary to applicable law); (iii) use output from the Services to develop models that compete with OpenAI; (iv) except as permitted through the API, use any automated or programmatic method to extract data or output from the Services, including scraping, web harvesting, or web data extraction; (v) represent that output from the Services was human-generated when it is not or otherwise violate our Usage Policies; (vii) buy, sell, or transfer API keys without our prior consent; or (viii) if you are using the API in connection with a website or application directed at children, send us any personal information of children under 13 or the applicable age of digital consent. You will comply with any rate limits and other requirements in our documentation. You may use Services only in geographies currently supported by OpenAI.
As far as I can see, only the OpenAI API terms of service has an anti-competition clause. Keep an eye out for that sort of clause in other contexts too.
