How Intelligent Caching and Smart Routing Cut LLM Costs

LLM API costs are the #1 concern for teams scaling AI features. Our AI Gateway's intelligent caching, smart routing, and fallback strategies can meaningfully reduce spend -- without sacrificing quality.

The Cost Problem

A single GPT-4 Turbo call costs $0.01-$0.03 per request. At 100K requests/day, that's $1,000-$3,000 per day in API costs alone. And that's just one model -- most teams use multiple providers for different use cases.

How the AI Gateway Helps

Semantic Caching -- Our cache doesn't just match exact strings. It uses embedding similarity to identify semantically equivalent queries. "What's the weather in NYC?" and "NYC weather today" hit the same cache entry.

Smart Routing -- Route requests to the cheapest model that meets your quality threshold. Use GPT-4 for complex reasoning, Claude for long documents, and Mistral for simple classification -- automatically.

Fallback Chains -- If your primary provider is down or rate-limited, requests automatically route to your backup. Zero downtime, zero code changes.

Start saving today -- the AI Gateway is included in all Pro plans and above.
