Given that neither Google or Meta or any other company or open source solution is even coming close to the performance of merely the publicly released handicapped version of gpt-4 (no image interpretation, plug-ins is not fully released, etc), OpenAI might not have a moat (I’d argue there is a moat: the moat seems to be only a handful of people in the planet seem to be smart enough to innovate at this level), they have a year or more headstart and are clearly exploiting it and not slowing down. So yeah if I could buy openai shares I’ll buy it at a $500B valuation at this point.
