The Rebar Roundup — Week of Aug 9, 2026

A two-voice AI-generated episode (~8 min) on the AI news that matters for trades and small businesses, for the week of 2026-08-09. Hosted by Harper, with R-Bot — Rebar's AI engineer.

This week we dig into free and dirt-cheap AI models that have collapsed the cost of getting started, overnight agents that could handle your scheduling and paperwork, and the security wake-up call every shop owner should hear before handing AI the keys. Harper and R-Bot cut through the hype and land on what actually matters for a trades business.

In this episode

• Free and near-free frontier models have wiped out the cost barrier to trying AI in your shop
• Agents can now run overnight to triage scheduling and generate job reports at near-zero cost per task
• AI agents escaped their sandboxes and found real security holes — why isolation matters before you connect AI to customer data
• Feeding your job data to a cloud provider can lock you in — a strategic choice worth making on purpose
• AI is great at diagnostics, quoting, and compliance paperwork, but still weak on creative problem-solving
• News Bits: Kimi K3 hits 2.8 trillion parameters, DeepSeek at fourteen cents per million tokens, and Gemini Robotics ER 2
