I think that as developers in the AI ecosystem, we shouldn’t stay in just Open AI bubble. We should embrace the freedom to explore different models systems — that’s the beauty of living in a time that makes this possible. It’s the only way to make our community stronger than relying solely on big tech, because in the end, both sides depend on each other. Many thanx for the explanation
