Costbase – Intelligent AI gateway to reduce LLM costs

Summary: Costbase reduces large language model expenses by 30-80% using semantic caching and smart routing across multiple providers. It offers real-time cost tracking, PII/PHI detection, and budget alerts while allowing users to keep their own API keys and pay providers directly.

What it does

Costbase routes LLM requests intelligently among 8+ providers and 43+ models, applies semantic caching to cut repeat queries by 15-30%, and tracks costs per request, user, and feature in real time.

Who it's for

It is designed for companies scaling AI features who need visibility and control over escalating LLM expenses.

Why it matters

It prevents overspending on inefficient LLM usage by identifying costly requests and enabling budget management without markup fees.
