①假如先行词是Open人工智能，就是定语从句和同位语an artificial-intelligence laboratory based in San Francisco并列，一同以非限制形式修饰Open人工智能；②若是先行词是anartificial-intelligence laboratory，就是定语从句和based短语并列，一同修饰它，但不该有逗号吧？个人倾向于②。由于假如按①剖析，and完全不必了。
想听听大咖专家老师们的建议，感谢！

3. GPT-3, as it is more commonly known, was developed by Open人工智能, an artificial-intelligence laboratory based in San Francisco, and which Mr Musk helped found.
