Brief

a16z's Yoko Li (2026-08-06) argues that agents should finish their own loops: instead of a human prompting, inspecting, and re-prompting, the system should iterate autonomously (revise text, try implementations, regen images). Her essay, "Knowing When to Stop: The Art of Making a Loop Converge," focuses on criteria and signals for loop convergence.

Why it matters

On 2026-08-06, a16z's Yoko Li argues that modern AI models can autonomously iterate — they can “produce another answer,” revise paragraphs, try alternative implementations, and generate images with more detail, different lighting, and stronger composition.

Key details

  • Li promotes 'loop engineering' where the agent performs the full prompt–inspect–revise cycle itself; the central technical challenge she identifies is 'knowing when to stop' (converge), analogous to human signals like tests turning green or PR review.

a16z's Yoko Li on the promise of agents that finish their own loops:

"An AI model can almost always produce another answer."

"It can revise the paragraph again. It can try another implementation. It can generate another image with more detail, different lighting, and a stronger composition."

"This is part of what makes the recent idea of loop engineering so compelling. Instead of a human prompting a model, inspecting the result, describing what went wrong, and prompting it again, we can ask the system to perform the whole cycle itself."

How can an AI model know when its work is done?

Well, how does a human know when our work is done.

A programmer waits for the tests to turn green or waits for PR review from their team. A designer
