There could be some trickery on the training side, i.e. maybe they spent way more than $6M to train it.
But it is clear that they did it without access to the infra that big tech has.
And on the run side, we can all verify how well it runs and people are also running it locally without internet access. There is no trickery there.
They are 20x cheaper than OpenAI if you run it on their servers and if you run it yourself, you only need a small investment in relatively affordable servers.
They have made it harder, but it's not really hard.
Just buy any regulated crypto and convert. Cake Wallet makes it easy, but there are many other ways.
I myself hold Bitcoin and Monero.
