NadirClaw vs AI Gateways: Why Smart Routing Beats Dumb Proxying

Every week there's a new "Top 5 AI Gateways" roundup. Bifrost, Cloudflare, Vercel, LiteLLM, Kong. They all do roughly the same thing: load balance, failover, cache, rate limit. Important stuff, but they're solving the wrong problem. The biggest cost lever isn't caching or failover. It's sending the right prompt to the right model. The math A dev.to article this week showed a 600x cost spread between the cheapest and most expensive LLM APIs. Even among production-grade models, you're looking at 20x differences. If 60% of your prompts are simple (formatting, classification, extraction, short Q&A), and you route those to a model that costs 10x less, you just cut your bill by 54%. No caching magic. No complex infrastructure. Just not using a $5/M-token model to answer "what's 2+2."
