Well, Jev doesn't meet any real compliance requirements but OpenAI's models do. So even if Jev is faster, any customers with compliance needs will obviously pick OpenAI because they can't pick Jev out of necessity.
Or even just- they've already procured OpenAI.
That's a big motivator.
I can run OpenAI on AWS Bedrock and Azure. I cannot run Jev on those cloud providers. For the many companies locked behind cloud providers, we don't have the same options.
