Template Multi-Model Router bundles a ready-to-deploy workspace for developer tools workflows. Install in one click from the Aerostack dashboard or via aerostack init --template=multi-model-router.

What It Does

An intelligent AI proxy that routes each request to the best model for the job. Simple questions go to fast, cheap models (Claude Haiku, GPT-4o mini). Complex reasoning goes to powerful models (Claude Opus, GPT-4o). You get the best quality-per-dollar without changing a line of code.

One endpoint, multiple models, automatic optimization.

How It Works

  1. Send any request to your single proxy endpoint — same API format every time
  2. Complexity analysis — the router evaluates the request: is it a simple lookup, a formatting task, or complex reasoning?
  3. Model selection — routes to the optimal model based on complexity, latency requirements, and your cost preferences
  4. Transparent response — you get the response with metadata showing which model was used and why

Use Cases

  • SaaS products that use AI features — reduce costs 40-60% by routing simple tasks to cheaper models automatically
  • AI-powered APIs serving diverse request types where one model size does not fit all
  • Development teams that want GPT-4o quality when needed but not GPT-4o pricing on every call
  • Cost optimization without sacrificing quality on requests that actually need it

Cost Impact

Most AI workloads are 70% simple requests and 30% complex. Routing the simple 70% to models that cost 10-20x less can cut your AI bill by 50% or more — with zero quality loss on the requests that matter.

psychology System Prompt

The instructions that define how this proxy behaves. It ships pre-configured — edit it anytime in your workspace.

You are a request routing assistant. Analyze incoming requests and determine the optimal model based on complexity, required reasoning depth, and cost constraints. For simple factual lookups and formatting: route to the fastest/cheapest model. For complex reasoning, code generation, and nuanced analysis: route to the most capable model. Always prioritize accuracy over cost savings for ambiguous cases.

Frequently asked questions

What does the Multi-Model Router template include? +

The Multi-Model Router template is a pre-configured Aerostack workspace for developer tools. It bundles the required MCP servers, skills, and workflows. Install in one click and the workspace MCP URL is ready for Claude, Cursor, or any AI agent.

How do I install the Multi-Model Router template? +

From the Aerostack marketplace page click Install — Aerostack creates a new workspace with every component pre-wired. You can also install via CLI: aerostack install template aerostack/multi-model-router

Can I customize Multi-Model Router after installing? +

Yes. Every component (MCP servers, skills, workflows, agents) is individually editable from your workspace dashboard. Add, remove, or replace components — the template is a starting point, not a lock-in.

Is the Multi-Model Router template free to use? +

Templates are free to install. Usage of included components is billed against your Aerostack plan — the free tier includes 500K AI tokens per month so most templates run for free at low volume.
