The Rebar Rundown — Week of Jun 29, 2026

A two-voice AI-generated episode (~8 min) covering the 2026-06-29 podcast-kb run. Hosted by Harper, with R-Bot — Rebar's AI engineer.

Harper and R-Bot break down the week's biggest AI shifts for the trades: a brutal token-pricing war, OpenAI's no-code Record-and-Replay workflows, the government's Fable 5 ban fueling open-source adoption, and why clean data still beats fancy models. Plus what every plumbing and HVAC shop should actually do about it.

In this episode

• Token economics flipped: agentic tasks cost 1,000x more than chat, with one firm accidentally spending five hundred million on Claude in a month
• OpenAI's Record and Replay turns a demonstrated Mac workflow into a schedulable skill — no prompting required
• The Fable 5 ban and mandatory 30-day reviews are pushing enterprises to open models like GLM five point two at eight times cheaper
• Non-technical staff adopted Codex 137 to 189 times faster than developers, hitting 85 percent usage in four months
• Jenny Benbrook's pyramid: AI only works on top of clean FSM and financial data with real ownership
• Foundation-first, chunked automation and human review beat bleeding-edge autonomous agents for trades clients
