The Rebar Roundup
Published · a fresh episode every Sunday
This week we dig into the AI stories that actually matter for a shop: Claude's cheaper agentic models and their closing pricing window, tiny fine-tuned phone models beating the giants, voice-to-invoice on the job site, and why most AI projects fail on broken processes, not bad tech. Plus a real-world trades example of AI cutting bid research from two weeks to one hour.
