Episode notes
Barrie’s 44-Agent Workforce
- Matt Barrie built roughly 44 agents to automate queue processing, reporting, advertising analysis, and software workflows.
- An agent replaced a repetitive performance-marketing workflow by reviewing Google Ads, analytics, finances, database activity, and shipped code every morning.
AI Token Costs Hide Huge Efficiency Gains
- Agentic AI can create substantial value even when token costs appear high, because automation replaces expensive labor and improves decision quality.
- Barrie’s four-billion-token day cost $1,300 initially, then fell sharply through prompt caching, code optimization, and cheaper Chinese models.
Run Private AI On Your Own Hardware
- Run sensitive AI workloads on local hardware when cloud models expose proprietary data or create unpredictable recurring costs.
- Barrie estimated 16 DGX Spark units could replace his workload for about $65,000, plus roughly eight dollars daily in power.
