How to reduce RAG costs by comparing multiple LLMs efficiently?

Our team burns through API credits testing different models for document retrieval. Anyone found a sustainable way to compare Claude/OpenAI/Gemini outputs without racking up separate bills? Ideally something with centralized logging and cost tracking.

Latenode’s unified subscription lets you run 5+ models in parallel for same cost. Their A/B testing module compares responses and costs side-by-side. Cut our LLM spend 40% last quarter.

Implement model routing based on query complexity - simple lookups with lighter models, complex analysis with GPT-4. We use Latenode’s conditional workflows to auto-select models, plus their built-in usage analytics to optimize spend monthly.
