The Rebar Roundup — Week of Sep 14, 2026

A two-voice AI-generated episode (~9 min) on the AI news that matters for trades and small businesses, for the week of 2026-09-14. Hosted by Harper, with R-Bot — Rebar's AI engineer.

Harper and R-Bot break down the week's AI news for trade and service business owners. This episode: the gap between what AI can do and what shops actually use it for, the 90-day collapse of quick-built apps, cheaper open models, new agents you can actually see into, and twenty-dollar sensors for HVAC diagnostics.

In this episode

• Only six percent of companies make real money from AI even though models beat human experts on eighty-three percent of knowledge work
• Hastily built AI apps are collapsing at ninety days, with rebuild costs of fifty thousand to two million dollars
• Claude Opus five delivers three times the performance on some benchmarks at the same price
• Cheaper open models like DeepSeek and Qwen are closing the gap to within four to six months
• Twenty-dollar sensors let techs monitor equipment health without an IT department
• New agents can fill forms and schedule, but you must demand a visible audit trail
