Auto Router vs Sonnet: Cost Savings vs Response Quality

Auto Router Functionality and Cost Comparison

Open Router's Auto Router feature automatically selects different LLMs based on the complexity of the context. For less complicated tasks, it might choose Gemini Flash 2.5, while more complex tasks get routed to Sonnet. The primary benefit is cost reduction: Auto Router requests cost approximately 0.00071 cents compared to 0.8 cents for direct Sonnet usage.

User Experience Comparison

A user who started with Sonnet 4.6 reported receiving "top tier" quality feedback from their OpenClaw or Telegram integration. After switching to Auto Router, they observed that AI responses became "loose, sloppy and overall trash." The user noted that the AI even admitted to the quality degradation when asked directly about it.

The user's conclusion: "You get what you pay for absolutely exists in this use case."

When to Consider Auto Router

According to the source, Auto Router might be suitable for "highly technical" users who can "navigate the jargon being spewed by the cheap LLM." This suggests the feature may work better for users who can interpret or filter lower-quality responses rather than relying on polished, production-ready output.
