Sahil Bansal shows how CodeRabbit, an open-source AI agent, caught a developer deploying an expensive M5 AWS instance when the product requirements demanded the cheapest option that met the specs. The agent analyzed the infrastructure code, calculated the actual CPU and RAM needs, and flagged that a cheaper T-family instance would work instead.

One very interesting example I saw in an open source repo was a developer was trying to deploy an M5 family AWS instance. For those of you who may not be familiar with it, that's one of the more expensive AWS compute instances. And the, there was a PRD related to the feature that the developer was trying to build for which they were deploying the M family instance. The PRD had a line item that said, please use the cheapest compute instance that fits the resource requirement. And our agent, CodeRabbit agent, was able to figure out, oh, you only need X amount of compute and Y amount of RAM based on what the Infras code said. You can get away with a T family. You don't need to use an M family. So we were able to flag, hey, you have this requirement in your PRD. Your code is in violation of that requirement.
