Mollick reframes AI choice as Models vs Apps vs Harnesses. The edge is no longer the model brain, but the harness that gives it hands. "AI that does things > AI that says things."

๐Ÿ” Featured Findings
Summary

Ethan Mollick (Wharton) published the latest installment of his periodic "which AI to use" guides, restructured for 2026's agentic landscape. Instead of just comparing models, he frames the choice across three layers: **Models** (the "brain in a jar"), **Apps** (interfaces), and **Harnesses** (the tools + workflow wrappers that give the brain "hands"). The central thesis: raw model performance is converging, so the strategic edge goes to the harness — the ecosystem that lets AI actually execute tasks, not just answer questions. He argues that "AI that does things is fundamentally more useful than AI that says things," and that the paradox of choice among AI tools has become the single biggest adoption barrier for non-experts.

Key Takeaway

The shift from "chatbot you talk to" to "agent that works for you" is the defining change of 2026. For practitioners and newsletter readers alike, the message is clear: stop obsessing over model leaderboards and start building workflows around harnesses that can swap engines as better models emerge.

Try to teach a novice Code or Codex and you will realize how baffling they are to many. They assume you know model names & thinking levels & projects vs. folders & skills & plugins & connectors, etc. Even just clicking "+" can lead to a flood of complexity.
