Model routers are becoming the load-balancing layer for AI

Brief

Model routers are emerging as AI’s load balancers: teams initially route all requests to top models (Opus, GPT-5.5/6) but many calls can be handled by cheaper/specialized models (Sonnet, GLM, Kimi, Qwen, DeepSeek) with minimal quality loss. Ramp says its Ramp Router, used across 100+ use cases, cut LLM costs by 30% while improving speed and intelligence and is now available broadly.

Why it matters

Model routers are becoming the load-balancing layer for AI: teams commonly start by sending everything to Opus or GPT-5.5/6 but find many requests can be served by Sonnet, GLM, Kimi, Qwen, or DeepSeek with almost no drop in quality.

Key details

  • Ramp reports that across 100+ use cases, their Ramp Router cut LLM costs by 30% while making features “smarter and faster,” and they’ve opened access at ramp.com/router.
  • The price–intelligence–latency frontier shifts weekly, creating an ongoing operational challenge to keep model selection up to date and avoid overspending or losing intelligence.

MODEL ROUTERS ARE BECOMING THE LOAD BALANCERS OF AI

Every AI team goes through this. You start by sending everything to Opus or GPT-5.5/6, then realize later that half those requests could've been handled by Sonnet, GLM, Kimi, Qwen, or DeepSeek with almost no drop in quality.

That's why model routing is becoming such an important layer. Instead of committing to one model, every request gets the model it actually needs

Every week, the price-intelligence-latency frontier shifts, and we expect this trend to continue

Across 100+ use cases in our product, keeping all up to date with the right model is a challenge -

Either we're losing out on intelligence for the dollars we spend, or we're spending too much money for the intelligence the feature needs

Ramp Router lets you benefit immediately without rewriting your application. We cut our LLM costs by 30%, while also making our features smarter and faster.

We built it for Ramp. Now we’re opening it up to everyone.
