If OpenAI makes their revenue off of charging exorbitant fees to use the LLMs, they'll no longer have incentive to ever open them (even if abuse / misuse concerns are addressed) AND they'll have no incentive to make them more efficient.
OpenAI has yet to show it can have a sustainable advantage. Every other player in the space benefits from an open model ecosystem and efficiency gains.
But yeah, they probably need to evolve from a (very good) two-trick pony into "the microsoft of AI" or something to stay afloat in the long run. That goes for the rest of the smaller AI companies as well though..
My money is on Deep Floyd (if and when it gets released)
Llama 65b is hopefully just the beginning of this trend. It outperforms OPT-175b.
