Latest / The Augur Dispatch / Who grades your AI grader? Allen AI's 52-point warning
Transcript
- 0:00SPEAKER_00: Allen AI changed the instructions given to an AI grader, and its accuracy fell from about 94% to about 41%.
- 0:08SPEAKER_00: The research ideas being graded hadn't changed.
- 0:11SPEAKER_00: Before you use a model's score to approve another model, you need to know what the grading instructions are doing to that score.
- 0:18SPEAKER_00: There's an important qualification here.
- 0:20SPEAKER_00: This wasn't simply a polite question becoming a blunt one.
- 0:24SPEAKER_00: The researchers removed a cue saying human reviewers had found one of the ideas novel.
- 0:29SPEAKER_00: They changed what the grader was told to assume.
- 0:32SPEAKER_00: This is the Augur dispatch for Wednesday, October 28th, 2026.
- 0:37SPEAKER_00: Augur's view is that the grading setup needs its own evaluation owner.
- 0:42SPEAKER_00: A score that looks convincing under one set of instructions hasn't earned the right to settle a release decision on its own.
- 0:49SPEAKER_00: Picture a product lead arriving at a release meeting with a reassuring chart.
- 0:53SPEAKER_00: The assistant's answers have improved, according to the model that grades them.
- 0:57SPEAKER_00: Nobody has changed the customer examples.
- 1:00SPEAKER_00: Everyone would like the meeting to end.
- 1:02SPEAKER_00: Asking to inspect the graders is unlikely to win the shortest meeting award, but it may be the most useful question in the room.
- 1:10SPEAKER_00: The reason teams use these graders is sensible.
- 1:13SPEAKER_00: If an assistant writes a customer response, there may be dozens of acceptable answers, and a rule that checks for one exact sentence won't tell you whether the response helped.
- 1:23SPEAKER_00: A model can read the meaning, apply a rubric, and return a score.
- 1:27SPEAKER_00: A rubric is just the criteria you're asking it to use.
- 1:30SPEAKER_00: Human review costs time, so an automated first pass can make testing practical at a scale people couldn't otherwise manage.
- 1:38SPEAKER_00: Anthropic has described a simple grading call that returned scores and a pass or fail judgment, and said it matched human judgments better than more elaborate arrangements in its research system.
- 1:50SPEAKER_00: That is a reason to take the method seriously.
- 1:53SPEAKER_00: It isn't a guarantee that the same approach will work for your assistant.
- 1:57SPEAKER_00: Agreement with humans is evidence about the examples and instructions you tested.
- 2:01SPEAKER_00: Changing either can change what that agreement means.
- 2:04SPEAKER_00: This is where Allen AI's experiment becomes useful.
- 2:08SPEAKER_00: Its study asks models to judge whether research ideas are novel, meaning they contribute something new rather than repackage existing work.
- 2:16SPEAKER_00: That's a difficult judgment even before you automate it.
- 2:20SPEAKER_00: The researchers built a pool of about 150 high-novelty ideas from accepted papers at a major machine learning conference.
- 2:27SPEAKER_00: They didn't just assume accepted papers must be original.
- 2:31SPEAKER_00: They looked for explicit praise of originality in the reviews and excluded papers where a reviewer disputed it.
- 2:37SPEAKER_00: They also collected lower novelty human ideas and produced a separate set of ideas with a basic AI generator.
- 2:44SPEAKER_00: Those different populations turned out to matter.
- 2:48SPEAKER_00: The striking result came when GPT-5.4 compared strong human ideas with generated ideas.
- 2:55SPEAKER_00: One prompt told it that reviewers had found exactly one idea novel.
- 2:59SPEAKER_00: Another left that statement out.
- 3:01SPEAKER_00: The measured accuracy dropped by more than 50 percentage points, more than half the verdicts changed on the same pairs.
- 3:09SPEAKER_00: But the paper says the prompts aren't equivalent, and we shouldn't quietly erase that sentence because it makes the headline less tidy.
- 3:16SPEAKER_00: Giving the judge information about prior reviewers can change its expectations.
- 3:21SPEAKER_00: This experiment doesn't isolate the effect of swapping one harmless phrase for another.
- 3:26SPEAKER_00: There's also uncertainty in the answer key.
- 3:29SPEAKER_00: The researchers assumed the basic generators' ideas were less novel than the selected human ideas.
- 3:35SPEAKER_00: One expert checked 30 pairs and agreed with that ordering in every case, but most of those were difficult cases for the strongest judge.
- 3:43SPEAKER_00: It wasn't a complete independent review of the whole collection.
- 3:47SPEAKER_00: Those limits affect how confidently we should interpret the accuracy figures.
- 3:51SPEAKER_00: They don't make the changed vertex disappear.
- 3:54SPEAKER_00: Two opposing answers to the same comparison can't both be the right answer.
- 3:59SPEAKER_00: On human-only pairs, the same prompt change moved GPT-5.4 by about seven points.
- 4:05SPEAKER_00: Another model moved by 21.
- 4:07SPEAKER_00: The grader that looked steadier on human writing wasn't necessarily steadier when generated ideas entered the comparison.
- 4:14SPEAKER_00: For the product lead in our imagined meeting, that changes the follow-up.
- 4:18SPEAKER_00: It isn't enough to ask whether the grader once agreed with people.
- 4:22SPEAKER_00: Ask whether the examples in that check resemble the output the team is producing now.
- 4:27SPEAKER_00: There is a reasonable defense of the grader.
- 4:30SPEAKER_00: New instructions can contain relevant information.
- 4:33SPEAKER_00: A human reviewer might change a judgment after learning the same thing, and research originality is a long way from checking whether a response includes the required account number.
- 4:43SPEAKER_00: Augur wouldn't use this paper to declare every automated score worthless.
- 4:48SPEAKER_00: That would repeat the mistake of stretching one measurement beyond the job it actually tested.
- 4:53SPEAKER_00: The narrower problem is still consequential.
- 4:56SPEAKER_00: If your team changes the instructions, adds a claim about what experts believe, or switches the kind of output being evaluated, the score may stop meaning what you thought it meant.
- 5:07SPEAKER_00: Imagine the engineer responsible for improving that score.
- 5:10SPEAKER_00: They've been adjusting the assistance prompts and checking each version against the same judge.
- 5:15SPEAKER_00: If the judge has an unnoticed preference, the engineer can spend a week satisfying it without making customers any better off.
- 5:23SPEAKER_00: The chart may be accurate about the graders' preferences.
- 5:26SPEAKER_00: That's an awkward thing to discover after the launch email.
- 5:30SPEAKER_00: Other research raises related concerns.
- 5:32SPEAKER_00: An audit of vulnerability analysis found that roughly 60% of correct model verdicts came with fabricated or unverifiable claims in their explanations.
- 5:42SPEAKER_00: That's security analysis, not this novelty experiment.
- 5:46SPEAKER_00: And it doesn't prove why Al NAI's judges change their minds.
- 5:50SPEAKER_00: It does explain why a plausible explanation shouldn't end the inspection.
- 5:54SPEAKER_00: A correct-looking verdict and a dependable reason for reaching it are separate things to check.
- 6:00SPEAKER_00: The practical response is a small comparison with a control.
- 6:04SPEAKER_00: Keep a sample of past outputs fixed, including cases the team considers unambiguous.
- 6:09SPEAKER_00: Run the original grading prompt again to see how often it changes its mind without an edit.
- 6:15SPEAKER_00: Then try two rewrites that another person has checked for the same meaning.
- 6:19SPEAKER_00: Keep the criteria and information intact.
- 6:22SPEAKER_00: If you want to test a reviewer authority queue, do that separately and label it as a different experiment.
- 6:28SPEAKER_00: Compare the changes with the repeated original baseline.
- 6:31SPEAKER_00: Have the evaluation owner inspect consequential reversals before the next rollout meeting.
- 6:36SPEAKER_00: A few stable examples don't prove the judge is safe, and a reversal doesn't prove every previous score was wrong.
- 6:44SPEAKER_00: The useful outcome is knowing which decisions need human attention.
- 6:48SPEAKER_00: Don't keep editing the instructions until the result turns green.
- 6:51SPEAKER_00: A grading prompt shouldn't have to negotiate its way onto the status slide.
- 6:56SPEAKER_00: Use fixed checks when the work permits them.
- 6:59SPEAKER_00: Wheaton Labs describes checking coding agent work against known correct spreadsheets, which gives those outputs a reference that doesn't change its opinion about the wording of a question.
- 7:09SPEAKER_00: For less definite work, keep the difficult customer examples and the human decisions made about them.
- 7:15SPEAKER_00: That history can make your evaluation better suited to your business.
- 7:19SPEAKER_00: Buying the same grading model as everyone else won't create that history for you.
- 7:24SPEAKER_00: A few signals remain on the clock in the wider written dispatch.
- 7:28SPEAKER_00: Anthropic has filed for a proposed NASDAQ listing under ANT.
- 7:32SPEAKER_00: A filing isn't a first trade.
- 7:34SPEAKER_00: Its new government discount is available for direct purchases, with cloud provider discounts planned in the coming months.
- 7:40SPEAKER_00: Watch for disclosed state or city contracts under those terms.
- 7:44SPEAKER_00: Allen AI's benchmark and code are available for further testing.
- 7:49SPEAKER_00: Evidence on narrower grading tasks would tell us how far this concern extends.
- 7:54SPEAKER_00: Google Research reports an offline learning method that retains information in model weights.
- 7:59SPEAKER_00: A product appearance would be the next useful signal.
- 8:02SPEAKER_00: DeepMind's Genie 4 is already entering a research preview for trusted testers.
- 8:07SPEAKER_00: Broader developer access and usable terms remain worth watching.
- 8:11SPEAKER_00: The written brief with every source is at augerdispatch.ai.
- 8:16SPEAKER_00: Portions of the Augur Dispatch are AI generated.
- 8:19SPEAKER_00: That is the Augur Dispatch for Wednesday, October 28th, 2026.
- 8:24SPEAKER_00: Thank you for listening.
