How I Cut My LLM API Costs by 70% Without Touching My Code

说明与用途

通过 AI 网关实现 LLM API 成本降低 70%：所有请求统一通过网关路由，动态选择最便宜的模型，缓存重复请求，并采用按使用付费模式，无需改动代码。

问题

High monthly LLM API costs due to hardcoded provider endpoints and lack of dynamic pricing awareness.

结果

Reduced monthly LLM API spend from ~$200 to ~$60 (68% savings) without changing application code or user experience.

工作流

• Spin up an AI gateway locally or use a pay‑as‑you‑go service
• Configure provider pool and routing rules in YAML/JSON
• Point test environment to the gateway and run existing tests
• Swap production base URL to gateway endpoint
• Monitor logs and analytics for a week to confirm stability

证据

I was spending $200 a month on AI APIs. Now I'm down to $60

来源

The gateway takes my request, checks which provider currently offers the best price for that model category, and routes accordingly.

The cost comparison after a full month: Provider fees $185 → $52, Gateway usage $8, Total $185 → $60
