Subagents help you "Control costs by routing tasks to faster, cheaper models like Haiku"
as labeled
Observed
Confirmed: per-subagent model frontmatter routes tasks to cheaper models as documented. One undisclosed default worth noting: subagents default to model: inherit and bill at the parent session's model — a 62-definition plugin audit found zero agent definitions requiring Opus, and the feature request for a global subagent model cap (#26179) was closed stale on 2026-03-21.
