AI Engineering3 production patterns for AI agents and how to evaluate each one
A local coding agent, an in-app customer assistant, and an AI SRE triaging production logs may all use the same model class—but not the same harness, eval plan,… Sara Verdi July 10, 2026 9 min read -
AI EngineeringWhat is a loop in AI engineering, anyway?
The AI engineering world is using “loop” to describe several different agent architectures. This post maps execution loops, task loops, product loops, system loops, and the human oversight… Aparna Dhinakaran Laurie Voss July 10, 2026 10 min read -
AI EngineeringThe agent is the user now: lessons from the founder of WorkOS
WorkOS founder Michael Grinich explains why the next era of AI engineering depends on the systems around agents: identity, permissions, evals, memory, and feedback loops that keep autonomous… Aaron Winston July 8, 2026 9 min read -
AI EngineeringOwn the loop: A field guide to agent harnesses
As models become cheaper and more interchangeable, the durable advantage shifts to the agent harness: the loop, tools, memory, permissions, and workflow you can own and refine. Aparna Dhinakaran July 6, 2026 8 min read -
AI EngineeringWhy AI token costs don’t tell you if your AI is working
Token spend does not prove AI is creating value. Teams need cost-per-outcome metrics that connect AI usage to resolved tickets, accepted code, shipped features, and other business results. Laurie Voss June 19, 2026 9 min read
Don’t ship vibes.
