I think that might have been more true several 8-12 months ago. But now it feels like the momentum has swung towards open source. Multiple models are close to or exceeding GPT 3.5 now. They can do a lot of useful things.
I have come to the conclusion that as much as possible I should try to wean myself off of OpenAI immediately. Because it's just not necessary or desirable to be tied to a single vendor anymore for many tasks. And in 2024 the open source capabilities will continue to increase. Soon everyone with a relatively new computer will be running things like LLMs locally. Within a couple of years it will be integrated into every OS or browser.
