Claude Code tool cuts costs by 51% using dynamic model routing

By PulseAugur Editorial · [1 sources] ·

A developer has created an open-source tool called AutoMode for Claude Code that dynamically selects the most cost-effective Anthropic model (Haiku, Sonnet, or Opus) based on the complexity and risk of a given task. Initial benchmarks showed AutoMode costing more than using Opus alone due to a rule that defaulted risky tasks to Opus. After refining the logic to make Opus a reward for failing checks or blocked changes, AutoMode achieved significant cost savings, with Haiku handling simple questions and Sonnet managing more complex coding tasks, resulting in a 51% reduction compared to using Opus exclusively. AI

IMPACT Developers can significantly reduce AI inference costs by implementing dynamic model selection based on task complexity.

    My Claude Code router cost more than Opus. Here's what the benchmark taught me

    <p>I built AutoMode because most of my Claude Code sessions look the same. I ask a quick question, then run a real task, ask another question, then do a harder task. And by default all of it runs on Opus.</p> <p>AutoMode is a free, open source (MIT) Claude Code mod. For every pro…
