Verifiability

What can be checked cheaply can be automated, delegated or optimised; what cannot be checked stays hard, and is where judgment lives.

How verifiable a task is now predicts how automatable it is, the way specifiability predicted it in the 1980s.

  1. Andrej Karpathy Founding member of OpenAI and former director of AI at Tesla The more a task/job is verifiable, the more amenable it is to automation in the new programming paradigm. Verifiabilitykarpathy.bearblog.dev · 17 Nov 2025
    The more a task/job is verifiable, the more amenable it is to automation in the new programming paradigm.

A verifiable task can be optimised by reinforcement learning until a neural network performs it extremely well.

  1. Andrej Karpathy Founding member of OpenAI and former director of AI at Tesla If a task/job is verifiable, then it is optimizable directly or via reinforcement learning, and a neural net can be trained to work extremely well. Verifiabilitykarpathy.bearblog.dev · 17 Nov 2025
    If a task/job is verifiable, then it is optimizable directly or via reinforcement learning, and a neural net can be trained to work extremely well.

Reinforcement learning leaves models sharply jagged: on the rails of a verifiable domain they are superintelligent, off them everything meanders.

  1. Andrej Karpathy Founding member of OpenAI and former director of AI at Tesla And so you're kind of like you're either on rails and you're part of the super intelligence circuits or you're not on rails and you're outside of the verifiable domains and suddenly everything kind of just like meanders.

A language-agnostic conformance suite is the most powerful thing you can hand a coding agent, because the whole instruction becomes: write code until these tests pass.

  1. Simon Willison Co-creator of Django and creator of Datasette And what you can do if you've got one of these conformance suites is you can give it to a a good agent and say, "Write code until this test suite passes." And it kind of will. Simon Willison: Engineering practices that make coding agents work - The Pragmatic Summityoutube.com · 19 Mar 2026 · 8:37 into the videoAll korrents from this video

A team can stop reading the code it ships, but only by first working out how its agents are to prove that what they wrote actually works.

  1. Simon Willison Co-creator of Django and creator of Datasette it turns out you can do this if you think really hard about okay, how do I have agents prove to me that the stuff they've written works?

AI systems are much better at tasks whose correctness can be verified than at tasks whose correctness cannot be checked.

    AI is still in a state where it is much better at verifiable tasks than non-verifiable tasks.

Software engineering agents will work before any other kind of agent, because code is the one domain where the machine can check its own answer.

Feedback loops

  1. Dylan Patel Founder and chief executive of SemiAnalysis But really the software engineering agents I think can be done faster sooner than any other agent because it is a verifiable domain. You can always unit test or compile, and there's many different regions of it can inspect the whole code base at once, which no engineer really can.

Loop engineering works exactly as far as verification does: make a problem very verifiable and you can treat it as a black box and let the model run.

  1. Dex Horthy Founder of the agent company HumanLayer And I think the lesson in loops engineering is like if you can make a problem very verifiable, you can kind of like treat it like a black box Context engineering with Dex Horthyyoutube.com · 15 Jul 2026 · 0:34:38 into the videoAll korrents from this video

The skill that matters now is not prompt engineering but giving a model a way to verify its own work, and it is the thing people most often get wrong.

  1. Boris Cherny Creator of Claude Code at Anthropic I think the skill nowadays is less about prompt engineering and more about figuring out how do you give Claude a hard task that seems a little bit too hard. And then how do you make it possible for Claude to verify its work along the way? And the verification I think is probably the single most important thing that people do not get right Boris Cherny: We Cut 80% of Claude Code's Promptyoutube.com · 27 Jul 2026 · 20:13 into the videoAll korrents from this video

The structures of science now have to change, because the scarce thing is no longer proposing theories but verifying and evaluating the thousands anyone can now propose.

Value moves to what stays scarce

  1. Terence Tao So, we're now in a situation where suddenly people can generate thousands of theories for a given scientific problem. And now we have to to verify them, evaluate them and this is something which we we have to to change our structures of science to actually sort this out.

The one genuine uncertainty left about AI capability is tasks nobody can verify — planning a Mars mission, discovering CRISPR, writing a novel.

  1. Dario Amodei Co-founder and CEO of Anthropic My one little bit, the one little bit of of fundamental uncertainty even on long time scales is this thing about tasks that aren't verifiable. Like, planning a mission to Mars, like, uh you know, doing some fundamental scientific discovery like like CRISPR, like, you know, writing a writing a novel. Hard to hard to verify those tasks.

A machine can complete the task and completely miss the job -- coding makes this easy to see precisely because its tasks are so legible and verifiable.
