The flexibility on switching LLM for cost optimisation or quality is great for scaled use cases.
Something seems off here, OP has an extra $1500 a month for over a year and then finally noticed. They then instead of pausing or migrating “expensive” services, stop paying and then AWS terminate as expected.
Feel there is more to this story than AWS being mean.

You don’t need a vector database or graph, it really depends on your existing infrastructure , file types and needs.
The newer “agent” search approach can just query a file system or api. It’s slightly slower but easier to setup and maintain as no extra infrastructure.
