Sub-agents, cost arbitrage, and why one person with AI can outpace a team
JANEL LOI
01 / 12Three walls I kept hitting.
A million ideas, 24 hours. Building everything myself was a losing game.
Developers cost $50–150/hr. A simple site: $5,000–10,000. That math does not work for side projects.
Solo execution meant projects took weeks. By then, motivation was gone.
"Build me a market research plan for my client." Here's what happens next.
Research in parallel: AI tools for a client across 7 categories.
What would take a full afternoon took 20 minutes. Five workers hit different angles at once and compiled into a tailored report.
04 / 12Same task quality. Wildly different price.
98% cheaper for research, migrations, audits, and content work
05 / 12One client research project: 7 parallel agents, web searches and summarization.
All of these were built by me + AI workers. No dev team.
Parallel research across 7 categories, 50+ tools evaluated, tailored recommendations in minutes
Retro terminal learning game with 6 chapters and a sandbox mode
Real-time monitoring for an AI sub-agent fleet
100+ how-things-work articles on science, tech, and everyday life, fully agent-written
Read-later app with newsletter feeds and offline caching
Tasks where MiniMax matches Claude quality at a fraction of the cost.
Web searches, article extraction, competitive analysis, summarization
Migrations, HTML-to-Markdown, drafts, documentation, repetitive copy
CSV transforms, dataset cleaning, report generation, bulk formatting
Rename variables, update imports, restructure files, lint fixes
Link checking, HTML validation, broken image scans, accessibility
Product descriptions, UI text, tag lines, structured metadata
MiniMax is what I use — but any cheap model works. Setup takes about 5 minutes.
Everything you need to get started and understand how this actually works under the hood.
agents.defaults.subagents.model to MiniMax in your config. Workers inherit it automatically. Your main agent stays on Claude. Best of both worlds.
Four things I know to be true.
Sub-agents let me do 10x more work in the same time
MiniMax costs 98% less than Claude for the same output quality
I set the direction. The AI orchestrator manages execution end to end
Results: 10+ apps shipped, $400+ saved, infinite scale
One person with AI can do what used to take a team. This is not theory. I am living it.
