When you need a tool that does not offer cost tracking, guardrails, load balancing, and logging, as these are key features of litellm.

When should I avoid rtk?

If you are already using a different tool named 'rtk' (such as Rust Type Kit), as there might be a name collision that could cause confusion or errors. When you are working in an environment where Rust binaries are not supported or where you cannot add a binary to your PATH. If your development workflow does not involve AI-assisted coding or infrastructure as code tools, as rtk's optimizations are specifically tailored for these use cases.
