Why The Harness Is Now More Valuable Than The Model

In this episode

I sat down with my co-founder Jonathan for our weekly AI clarity breakdown. We get into Anthropic's best model getting banned by the US government and the four open weight coding models that shipped before they could even respond, why engineering leaders need to stop building their agent stack on a single provider, Claude Code Artifacts launching on the heels of the Fable 5 fallout, and Vercel dropping Eve, their opinionated "Next.js for agents" framework already running 100+ production agents with a 32x ROI on their autonomous SDR.

What's the meta this week: four teams independently converged on the same agent architecture without talking to each other, the model is the engine, the harness is the car, and that's where the real moat is. We also go deep on Codex Record & Replay and App Shots with live demos.

If you're an AI builder trying to figure out what stack to bet on, how to structure your harness, or just keeping up with the meta as it moves fast, this episode covers all of it.

Hosted by Robert Ta and Jonathan McCoy, co-founders of Clarity, reporting from the front lines of building an AI company.

Every week

AI clarity for founders, builders and tech executives. News with real takes, the memes that made us laugh, and the tactical meta we are testing on ourselves.
