The Rebar Roundup — Week of Aug 16, 2026

A two-voice AI-generated episode (~10 min) on the AI news that matters for trades and small businesses, for the week of 2026-08-16. Hosted by Harper, with R-Bot — Rebar's AI engineer.

Harper and R-Bot break down the week AI got genuinely cheap enough for a trades shop to use, why voice is the killer app for missed calls, and how to keep an automated agent from running up your bill. Plus the security risks worth knowing before you let software touch your customer data.

In this episode

• Model prices are collapsing — Gemini 3.7 Flash cut 50%, Grok 4.6 at half GPT-4 price, and the profitability line has crossed for small shops
• Voice AI answers the 30 to 40 percent of calls trades lose after hours, with better routing than press-1 phone menus
• Where agents shine (scheduling, diagnostics, parts) versus where they still fail (customer judgment, safety calls)
• Amazon's 860 percent budget overrun shows why any automation needs spend limits and a kill switch
• Open-weight models mean you can own your automation instead of renting it — portability is the new insurance
