Cut AI API costs 60% overnight.

Route requests to the cheapest capable model. Pay only 10% of savings.

The Problem

Teams using Claude, GPT, and Gemini APIs are routing every request to their most expensive model by default—even simple text extraction or Q&A that doesn't need GPT-5 or Claude Opus. This wastes 50-70% of AI spend. Most companies either build janky in-house routing logic or manually manage model selection, both approaches requiring engineering time and constant tweaking.

The Solution

CostRouter is an API gateway that sits between your app and your AI providers. It analyzes each request's complexity (length, keywords, structure) and routes to the cheapest model that can handle it—Llama for simple tasks, Gemini Flash for medium complexity, GPT-5/Claude for reasoning-heavy work. One-line integration: just change your OpenAI base_url. We charge 10% of verified savings, so there's zero upfront cost.

Automatic complexity scoring: analyzes request length, keywords, and structure to route intelligently
One-line integration: change your OpenAI base_url, no SDK rewrites needed
Multi-model support: Llama 4 Scout, Gemini 3 Flash, GPT-5.2, Claude Opus—add your own
Request logging & audit trail: track which models handled what, replay edge cases
Custom routing rules: override complexity scores for specific use cases or customers
Spend dashboard: real-time savings tracker, per-endpoint breakdown, cost projections
