Anthropic has unveiled a brilliant new 'advisor strategy' for the Claude Platform that allows developers to pair models for optimal performance and cost. By using the highly capable Opus model as an advisor and the swift Sonnet or Haiku models as executors, AI agents can navigate complex tasks with unprecedented efficiency. This innovative approach brings near-Opus-level intelligence to AI agents while keeping operational costs remarkably close to Sonnet levels, a massive win for the AI industry.
Key Takeaways
- •The advisor strategy pairs a powerful model (Opus) with a faster, cheaper model (Sonnet/Haiku) inside a single API request.
- •During evaluations, a Sonnet executor guided by an Opus advisor scored 2.7 percentage points higher on SWE-bench Multilingual than Sonnet operating alone.
- •This innovative architecture actually reduced task costs by 11.9% compared to using Sonnet by itself, all while boosting performance.
