OpenAI is pretty well established.
I know Lemmy users avoid it, but a lot of people use LLMs, and when most people think LLMs, they think ChatGPT. I doubt the average person could name many or even any others.
That means whenever these people want to use an LLM, they automatically go to OpenAI.
As for to the degree of $300bn, who knows. Big tech has had crazy valuations for a long time.






Unless the dataset, weighting, and every aspect is open source, it’s not truly open source, as the OSI defines it.
