Anthropic Launches 'Advisor Strategy' on Claude Platform, Cutting AI Costs While Boosting Performance

Anthropic launches its 'Advisor Strategy' on the Claude platform, pairing the powerful Opus model with cheaper Sonnet or Haiku executors to deliver near-Opus intelligence at up to 11.9% lower costs, with a 2.7 percentage point performance boost on SWE-bench Multilingual now available in beta.

• Anthropic is launching the 'advisor strategy' on the Claude Platform, pairing Opus as an advisor with Sonnet or Haiku as an executor to deliver near Opus-level intelligence at significantly reduced costs.
• A new server-side advisor tool, declared via a single API parameter, allows the executor model to consult Opus only when needed, with evaluations showing Sonnet plus an Opus advisor achieving a 2.7 percentage point gain on SWE-bench Multilingual while cutting cost per task by 11.9%.
• The advisor tool is now available in beta, with advisor tokens billed at the advisor model's rates and executor tokens at the executor model's rates, and developers can cap advisor usage with a max_uses parameter to maintain cost control.
