One of our vendors insisted on whitelisting the IPs we were going to call them from, and our deployments went through AWS copilot/Fargate directly to the public subnets. Management had fired the only person with infrastructure experience a few months ago (very small company), and nobody left knew anything about networking.
Within about a week, Phind brought me from questions like "What is a VPC?" "What is a subnet?" to having set up the NAT gateways, diagnosing deploy problems and setting up the VPC endpoints in AWS' crazy complicated setup, and gotten our app onto the private subnet and routing outbound traffic through the NAT for that vendor.
Yes, it occasionally spit out nonsense (using the free/instant model). I even caught it blatantly lying about its sources once. Even so, once I asked the right questions it helped me learn and execute so much faster than I would have trying to cobble understanding through ordinary google searches, docs, and blog posts.
Strongly recommended if you're ever wading into a new/unfamiliar topic.
