> regulation should focus on ensuring the safety of AIs once they are ready to be put into widespread use - this would allow companies and individuals to research new AIs freely while still ensuring that AI products are properly reviewed.
While in general I share the view that _research_ should be unencumbered, but deployment should be regulated, I do take issue with your view that safety only matters once they are ready for "widespread use". A tool which is made available in a limited beta can still be harmful, misleading, or too-easily support irresponsible or malicious purposes, and in some cases the harms could be _enabled_ by the fact that the release is limited.
For example, if next month you developed a model that could produce extremely high quality video clips from text and reference images, you did a small, gated beta release with no PR, and one of your beta testers immediately uses it to make e.g. highly realistic revenge porn. Because almost no one is aware of the stunning new quality of outputs produced by your model, most people don't believe the victim when they assert that the footage is fake.
I would suggest that the first non-private (e.g. non-employee) release of a tool should make it subject to regulation. If I open a restaurant, on my first night I'm expected to be in compliance with basic health and safety regulations, no matter how few customers I have. If I design and sell a widget that does X, even for the first one I sell, my understanding is there's an concept of an implied requirement that my widgets must actually be "fit for purpose" for X; I cannot sell a "rain coat" made of gauze which offers no protection from rain, and I cannot sell a "smoke detector" which doesn't effectively detect smoke. Why should low-volume AI/ML products get a pass?
