Tier 3: High-Velocity Subagent EngineRole: Finder Subagent

Best Paired With: Claude 3.7 Sonnet as Lead Planner

High throughput and low pricing make it the premier engine for concurrent Coder and Finder jobs.

Git Worktree Isolation Advantage:

Executes parallel bug fixes across isolated worktrees without file contention.

What Developers & Practitioners Are Saying

Real-world field observations, production strengths, and developer consensus

Field Consensus

"High-volume workhorse offering 1M context at ultra-budget rates ($0.075/M input)."

Verified Real-World Strengths

  • Near-zero cost for processing massive logs and documentation dumps
  • Fast 180 TPS generation speed
  • Strong multimodal support

Production Caveats & Gaps

  • Can lose track of complex negative instructions in long prompts
Benchmark Reality Check

What the benchmark tests: Tests low-cost context ingestion and rapid summarization.

Production caveat: Not recommended for deep AST refactoring; best deployed for high-volume context analysis.
