No, it is still an anti pattern.

Autogenerated code falls into two categories:

1. Code templates, which prepare some stubs but you need to complete it manually. This is what openapi-generator does, and this is anti-pattern because very rarely this approach can't be avoided in favour of simply using code constructs like inheritance or composition.

2. Intermediary code, which is not to be updated manually and is fed directly into interpreter or compiler. In compiled languages it is fine, as this intermediary code is not executed directly; what matters is whether it compiles. In interpreted languages, however, that code gets executed directly, and it can be really difficult to debug (as there is an additional level of abstraction, introduced by the macro). But ultimately there is no need for this type of code, as most interpreted languages (Python and JavaScript definitely) allow dynamic construction of various programming constructs (like classes and functions) on the fly.
