Go back 5 years and ask anyone on this site what companies do you think will be the most open about AI in the future OpenAI, Meta, or Google. I bet 10/10 people would pick OpenAI. Now today Meta and Google, both trillion dollars companies, are releasing very powerful open models with the ability to be used commercially. Ironic.
Not at all. When you're the underdog, it makes perfect sense to be open because you can profit from the work of the community and gain market share. Only after establishing some kind of dominance or monopoly it makes sense (profit wise) to switch to closed technology.
OpenAI was open, but is now the leader and closed up. Meta and Google need to play catch up, so they are open.
