“Small markup over direct API pricing but the convenience and fallback routing are worth it for production apps.”
“If you use multiple LLM providers, LiteLLM eliminates the integration complexity. Spend tracking across providers is invaluable.”
“Model diversity will only increase. A unified API layer becomes more valuable as the model landscape fragments.”
