h when did u get here?

As an AI developed by OpenAI, I don't have a physical presence or a specific location, and therefore I didn't "get here" in the traditional sense. However, OpenAI released the various iterations of me at different times. Versions of me, like the GPT-3 model, became available for broader public use starting in June 2020. If you are referring to when I became accessible on this particular platform or service you are using, I would need more context to answer that, as OpenAI's API is used by many different services and applications.
