OpenAI never promised to be open source.
They promised to create a lab where the benefits of AI would accrue to the people, not just existing tech giants.
They did that. They created a API where individuals and small businesses alike can use cutting edge AI technology via API. You have to pay, that's the only catch.
I don't see a DeepMind API. I don't see an Anthropic API. I don't see a Google Bard API. I don't see a FB Galactica API.
I hope OpenAI wins this battle.
