Total time: ~15 minutes. Cost: $0.00 in +LLM tokens. + +The same task via sub-agents would require 36 spawns × ~$0.03 = ~$1.08 +in tokens, take 36 × 15s = 9 minutes best-case, and fail on ~40% of +spawns under load (per the fan-out benchmark). + +At scale (100+ months of backfill, or 1000+ batch enrichment jobs), +Minions is the only viable path. Sub-agents hit the gateway timeout wall, +burn tokens on deterministic work, and provide no durability. + +## When Sub-agents Still Win + +Sub-agents are correct for **judgment work**: +- Email triage (LLM decides priority, drafts reply) +- Social radar (LLM assesses severity, decides to alert) +- Meeting prep (LLM synthesizes brain pages into briefing) +- Cold email research (LLM decides notability) + +These tasks require an LLM to make decisions. Minions can't do that — +its handlers are code, not models. The routing rule: + +> **Deterministic** (same input → same steps → same output) → **Minions** +> **Judgment** (input requires assessment/decision) → **Sub-agents** + +## One-Line Summary + +Minions completed a production tweet ingestion in 753ms for $0. +Sub-agents couldn't even spawn. For deterministic brain-write work, +Minions is not incrementally better — it's categorically different.
