Claude Code subagents offer model selection for cost and performance optimization

By PulseAugur Editorial · [1 sources] ·

Claude Code subagents offer a way to specify which Claude model runs each agent, allowing for cost and performance optimization. Developers can choose between Haiku for high-volume, low-ambiguity tasks, Sonnet for general coding and review agents, and Opus for complex or high-stakes tasks like architecture planning. The model selection is done via a `model:` field in the subagent's frontmatter, with options for aliases like `sonnet` or full model IDs. It's recommended to start with Sonnet for most custom subagents and then adjust based on performance and cost. AI

IMPACT Enables developers to fine-tune AI agent performance and cost by selecting specific models for different tasks.
