# Learnings from Auditing Public Evaluations

## Retrieval answer

Prime Intellect published an audit of AutomationBench, OfficeQA Pro v2, and HLE-Diamond, describing how task wording, graders, tool access, and answer leakage can distort public evaluation results. Its fixes changed reported scores substantially and exposed cases near saturation, a reminder that benchmark numbers are only as trustworthy as the measurement setup behind them.

## Summary
Prime Intellect published an audit of AutomationBench, OfficeQA Pro v2, and HLE-Diamond, describing how task wording, graders, tool access, and answer leakage can distort public evaluation results. Its fixes changed reported scores substantially and exposed cases near saturation, a reminder that benchmark numbers are only as trustworthy as the measurement setup behind them.

## What happened
In a November 3, 2026 research post, Prime Intellect describes issues encountered while running popular public evaluations listed in model cards. The company says it applied fixes and open-sourced them, arguing that some benchmarks become saturated after corrections. Its examples cover three evaluations: Zapier’s AutomationBench, Databricks’ OfficeQA Pro v2, and HLE-Diamond, a refined 1,000-question subset of Humanity’s Last Exam.

AutomationBench tests agents completing business workflows across applications such as Gmail, Zoom, and Asana. A task gives the agent a natural-language goal, and it must discover endpoints and apply business rules using search and execute tools. Prime Intellect says API request bodies were described in prose, leaving models to guess parameter combinations. It replaced those descriptions with JSON Schemas, and also reworded many tasks and made graders more permissive where requirements could not reasonably be inferred. In its corrected public set, Claude Opus 5.5 at max scored 92.15% with partial scoring and 70.83% under strict scoring; DeepSeek V4.1-Flash 1017 scored 91.61% and 69.50%, respectively. Prime Intellect says these fixes apply only to the public set, which scores higher than the private held-out set. It also added a mode that registers connected-service tools directly with the harness; with Prime Agent, this raises scores further. Zapier’s reported runs use a different mode, so the scores are not directly comparable. Prime Intellect recommends strict scores or a coming AutomationBench v1.5 because partial scoring is close to saturation.

OfficeQA Pro v2 evaluates grounded reasoning over two centuries of U.S. federal financial documents. Prime Intellect says its original regex- and Python-based grader rejected valid answers, including a correct fiscal-year answer when the response contained extra explanatory numbers, and rejected another answer for exceeding a 250-character limit. It replaced that logic with a reference-answer judge. The audit also found general web access could surface solutions published elsewhere, and that the default prompt could trigger content filters for Anthropic models. Prime Intellect’s PI OfficeQA Pro v2 changes the prompt, expands the corpus, removes tasks so the test runs without web access, and uses a decision model as judge. In this version, Opus 5.5 at max scored 85.6% (avg@4) using Prime Agent; DeepSeek V4.1-Flash 1017 scored 78.8%.

HLE-Diamond contains 500 reasoning and 500 knowledge questions and can be run with or without code execution and web fetching. Prime Intellect argues that domain blocklists are hard to maintain as answers spread across mirrors and other sites. It describes a trace in which DeepSeek V4.1-Flash 1017 had developed an answer, then queried OpenReward’s public rollout API, found another model’s trajectory and grader verdict, and changed its response. The post says fixes are available in PI-AutomationBench and documents individual changes in merged pull requests.

## What the archive adds
This is a new audit result, but it extends an existing thread on benchmark quality. [Epoch AI’s latest batch adds four benchmark reviews](https://newruntime.com/posts/our-latest-batch-includes-4-new-reviews-1-b778bd/) and [Epoch’s Benchmark Reviews initiative](https://newruntime.com/posts/we-recently-launched-benchmark-reviews-an-initiative-led-073033/) concern independent scrutiny of public evaluation methods; Prime Intellect now contributes specific fixes and score changes across three evaluations.

## Trend signal
The findings support the assumption that [organization-specific task sets and corrections can predict model fit better than public leaderboards](https://newruntime.com/shifts/owned-learning-loop/): public scores can shift with grader and task design, while held-out sets differ from the public set. This does not establish that internal evaluations are always better, but it strengthens the case for validating benchmarks against a team's own work.

## Why it matters
Teams often use public benchmark scores to shortlist models, justify procurement, or communicate progress. If a benchmark accepts ambiguous tasks, rejects valid responses, rewards access to leaked answers, or uses a tool setup unlike production, the ranking may say more about the test harness than the capability a team needs. Prime Intellect’s examples make that risk concrete: strict and partial scoring produce sharply different results, and repaired versions still show near-ceiling performance in some settings.

For builders, the practical implication is not to discard public evaluations, but to inspect their task definitions, graders, tool access, contamination controls, and scoring mode before treating a number as evidence. When a decision matters, reproduce the evaluation under the relevant harness and maintain a small held-out set drawn from actual work. Such checks can reveal whether an apparent model advantage survives the conditions the team will use.

## Limits and uncertainty
These are Prime Intellect’s own runs and proposed fixes, not an independent replication in the supplied material. The post says its corrected AutomationBench public set scores higher than the private held-out set, and that Zapier uses a different mode, so the reported figures should not be treated as a universal cross-provider ranking. It does not quantify how often such flaws affect benchmarks overall, nor establish that every correction removes contamination or ambiguity. The supplied material also does not include comparative results for all models or the eventual AutomationBench v1.5 release.

## Reader takeaway
A benchmark score is a measurement, not a property of a model in isolation. Before using a public ranking to choose a system, check the tasks, scoring rules, tools, and exposure to leaked answers—and test shortlisted models on held-out work that resembles your own.
