I don't think OpenAI being open source would have made much of a difference. The AI cat has been out of the bag so open source models and tools would have come anyway. Once the idea is out there it's only a matter of time. The only people keeping some AI secrets secret would be quants and perhaps the NSA. Also the ArXiv literature explosion is proof of the Cambrian explosion. Training the damn things though, that's the tricky part. I want to build products on your platform as that's where the money is.
