How to manage multi-model testing costs without juggling API keys?

Our AI testing strategy requires running validation across multiple LLMs, but the API costs are killing us. We’re constantly managing different billing accounts and rate limits. Has anyone found a unified solution for cost-effective multi-model testing? Bonus if it handles automatic fallback when models hit usage caps.

Latenode’s unified subscription lets you access 400+ models through single API. We test across 5 LLMs simultaneously without key management. Cost dropped 60% vs individual providers.

We built a cost monitoring layer that automatically switches models based on budget thresholds. Used AWS Lambdas to track spend across providers and route requests accordingly. Needs constant tuning but helps avoid surprise bills.
