Interesting, I looked into this. So The t4g.nano is 2 vCPU but only 0.5 GB RAM, so there's that trade off.

And from what I can tell as you bump more RAM, agent37 is around 5x cheaper: our 2 vCPU / 4 GB box is $4.94/mo (2/4/6 GB disk), vs AWS t4g.medium (the actual 2 vCPU / 4 GB Graviton box) at ~$24.50/mo
