The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing mechanism is the STORM multi-agent generation framework combined with human expert selection. Six specialized agents—a LaTeX math extractor, a query drafter (GPT-o1-Pro), an answer retriever that pulls derivations verbatim from the source paper, a context collector, a question refiner that makes problems self-contained, and an answer filter—turn a paper's formulas into question–answer pairs; human mathematicians then score each candidate on reasoning type, clarity, correctness, and reasoning density and keep only the top 100. The paper's illustrative example is the DPO closed-form solution $\pi_r(y|x) = \frac{1}{Z(x)}\pi_{\mathrm{ref}}(y|x)\exp(\frac{1}{\beta}r(x,y))$, where the generated answer reproduces the derivation from the KL-constrained objective with explicit heuristic cues. The mechanism is what turns raw paper text into self-contained, hard, human-like derivation problems.
What would settle it
Have an independent panel of professional mathematicians, with stated credentials and measured inter-annotator agreement, re-verify all 100 ground-truth derivations and re-score the model outputs blind; if a substantial share of derivations contain errors or if any model's re-scored solve rate exceeds 5%, the difficulty claim would be refuted.
Extended reading notes
Core claim
STORM-BORN is positioned as a third kind of math dataset, neither numerical word problems nor formal theorem-proving code, but natural-language derivations that reproduce the long chains, approximations, and heuristic trial-and-error a mathematician actually performs. The authors claim that from 2,000 pipeline-generated samples, expert mathematicians selected 100 with the highest reasoning density and correctness, and that these 100 defeat all six evaluated frontier models, with the best (GPT-o1-Pro) at 5% and DeepSeek-R1 at 4.6%. They also claim that supervised fine-tuning on only these 100 samples yields consistent accuracy gains on GSM8K, MATH, and AIME across TinyLLaMA, LLaMA2-7B, LLaMA3-8B, and Qwen2.5 models, and that a quality ablation shows the curated top-100 outperforms larger uncurated subsets. The runnable artifact is the dataset itself plus the STORM pipeline that produced it.
Load-bearing premise
The benchmark's difficulty and correctness rest on the assumption that the human mathematicians' quick review—about fifteen minutes per paper, roughly thirty seconds per problem—caught every error in the AI-generated derivations and scored the model outputs fairly.
Editorial extensions
If this is right
- If the <5% solve rate holds under independent scoring, STORM-BORN becomes a benchmark where frontier LLM progress on genuine research-level derivation can be tracked for the first time.
- Fine-tuning on just 100 STORM-BORN samples transfers to GSM8K, MATH, and AIME, so small curated derivation sets could be a data-efficient alternative to large arithmetic corpora.
- The quality ablation implies that uncurated synthetic data can actively hurt reasoning performance (full 2k set drops LLaMA2-7B GSM8K zero-shot from 7.96% to 5.16%), reinforcing the value of the human-in-the-loop filter.
- The same pipeline can be pointed at fresh papers to produce new hard benchmarks continuously, avoiding the staleness and contamination that affect static datasets.
Reading between the lines
- Inference: The <5% figure depends on human partial-credit scoring of long free-form derivations; a more mechanical scoring rule (e.g., checking only the final formula or key lemmas) could change model rankings even if the dataset is correct.
- Inference: The transfer gains may come from the derivations' dense heuristic cues and step length rather than from mathematical content per se; ablating problems by step count or by presence of approximation language would test this directly.
- Inference: The same multi-agent-plus-expert recipe could plausibly be reused for other reasoning-dense fields (theoretical physics, algorithms, formal methods) where derivation chains appear in papers.
- Inference: Because the dataset deliberately samples recent (2023–2024) papers, its difficulty may decay quickly as models train on those same papers; the pipeline is the durable contribution, not the static 100 items.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper introduces STORM-BORN, a dataset of 100 mathematical derivation problems extracted from recent arXiv papers through a human-in-the-loop, six-agent LLM pipeline. The authors claim that frontier LLMs such as GPT-o1-Pro solve fewer than 5% of these problems, and that fine-tuning on STORM-BORN improves performance on standard numerical reasoning benchmarks such as GSM8K, MATH, and AIME. The paper also reports a quality ablation suggesting that a small, expertly curated subset outperforms larger automatically generated subsets. The dataset and code are publicly released.
Significance. If the difficulty and generalization claims hold, STORM-BORN would be a useful complement to existing numerical-reasoning and formal-theorem-proving benchmarks, targeting informal, human-like derivations with dense reasoning steps. The multi-agent curation framework is described in unusual detail, including full prompts in the appendix, and the public release of code and data is a practical strength. The fine-tuning experiments cover several model families and show some positive transfer effects. However, the headline 'fewer than 5%' difficulty claim is not yet secure because the human evaluation protocol is under-specified: the number and credentials of expert graders, the scoring rubric, and inter-annotator agreement are all missing, and the reference answers were produced by the same LLM pipeline being evaluated. The fine-tuning evidence is also mixed, with several large degradations in Table 1 that are not discussed.
major comments (5)
- [§3.3 and §4.2] The central difficulty claim ("even most advanced models solve fewer than 5%") rests entirely on expert scoring, but the manuscript does not report how many experts graded each response, what their mathematical qualifications were, the detailed rubric used to decide "fully correct" versus "partial credit," or any inter-annotator agreement statistic. Section 3.3 states that one paper's ~30 samples were processed in about 15 minutes, i.e., roughly 30 seconds per sample, which is too fast to give confidence that the LLM-extracted reference derivations were carefully checked. This is load-bearing: if the reference derivations contain errors, or if the rubric penalizes correct alternative derivations, the reported solve rates measure annotation artifacts rather than mathematical difficulty. The authors should release the full scoring protocol, the individual expert scores, and an agreement analysis, and ideally have an independent set of graders re-score a random subset.
- [§3.2 and §4.2] The reference answers used as ground truth in the human evaluation were produced by the same GPT-o1-Pro-based multi-agent pipeline that is being evaluated (Query Draft Agent and Answer Retriever Agent), and §4.2 does not state that graders were instructed to credit mathematically correct derivations that differ stylistically from the reference. Since the dataset deliberately contains "human-like approximations and heuristic cues" rather than formal proofs, a model can produce a correct derivation with different notation, ordering, or heuristic choices. If graders compare against the reference solution rather than the underlying mathematical claim, the <5% result would be partly a rubric-mismatch artifact. I recommend a targeted experiment: have independent mathematicians score a random sample of model outputs against the original paper's derivation (not the pipeline's extracted answer) and report the difference.
- [§4.2 vs §4.3] The paper states in §4.2 that DeepSeek-R1 "assigns a perfect score to flawed cases" and therefore expert validation is essential, yet §4.3 uses DeepSeek-R1 as the automatic evaluator for the formula-derivation test set, scoring correctness, completeness, and similarity. This is internally inconsistent unless the authors show that DeepSeek-R1's scores are calibrated for that particular test set. They should either validate DeepSeek-R1's scores against human scores on a subsample, report the correlation or agreement, or use a different evaluation method.
- [Table 1 and §4.3] The abstract and §4.3 highlight positive fine-tuning gains, but Table 1 contains notable degradations that are not discussed: LLaMA3-8B drops from 50.27% to 45.49% on GSM8K-8shot and from 17.08% to 13.82% on MATH-4shot after fine-tuning, and LLaMA2-7B gains on MATH are near zero in the 4-shot setting. No confidence intervals or multiple-seed results are reported, so it is unclear whether the headline gains (7.84% on MATH for LLaMA3-8B, 9.12% on MATH-4shot for Qwen2.5-7B) are statistically meaningful. The claim that "the improvement increases with model capability" is not supported by these mixed results. Please report variance across seeds, significance tests or effect sizes, and discuss the drops explicitly.
- [§3.3 and Table 4] The procedure for selecting the "100 most difficult" samples is described only through four qualitative principles, although §3.3 says there are five core principles and lists only Q1 through Q4. There is no quantitative difficulty score, no threshold, and no inter-rater reliability for the selection. This matters for the quality-ablation claim in Table 4 that "top-100" outperforms larger subsets. The authors should define an operational difficulty metric or at least report the agreement among experts in choosing the top-100, and state how borderline samples were resolved.
minor comments (5)
- [Figure 3] The numerical labels in Figure 3 are difficult to parse: the value "5" appears between the model names and the percentage list, and the abstract's "fewer than 5%" should be reconciled with the exact values shown. Please reformat the figure so each bar has a clear value, and ensure the text matches those values.
- [Figure 1 and §4.1] The MiniF2F example is described as "can be solved with only one ring"; this should be "one `ring` tactic" or "one proof step" for clarity.
- [Introduction] The introduction says "Qwen improves by 16.7%" while the abstract and Table 1 report a 9.12% absolute gain on MATH-4shot; the 16.7% is a relative improvement. Please state which convention is being used in each place.
- [Appendix C] The heading for the derivation evaluation prompt reads "Prompt of Answer Retriever," but this is the evaluation prompt, not the Answer Retriever agent prompt. Please correct the heading.
- [Throughout] The model name is written inconsistently as "Deepseek-R1" in some places and "DeepSeek-R1" in others; please standardize.
Circularity Check
No circularity: STORM-BORN's ground truth comes from external papers, difficulty is an empirical measurement, and fine-tuning gains are evaluated on held-out benchmarks; noted evaluation inconsistencies are validity concerns, not circular derivation steps.
full rationale
STORM-BORN's questions are generated from formulas extracted from external academic papers, and the reference answers are retrieved from those same papers (Sec. 3.2), so the ground truth is an external source rather than a quantity fitted from model outputs. The benchmark difficulty claim (<5% solve rate) is an empirical measurement on a deliberately hard subset; while the selection criteria explicitly target difficulty and reasoning density (Sec. 3.3), that is standard benchmark curation, not an equation-level reduction. Fine-tuning gains are measured on held-out external benchmarks (GSM8K, MATH, AIME, and a NuminaMath-derived formula derivation test set), so the generalization claim is not equivalent to the training signal. The paper cites several works by its own authors, but only as related-work context (e.g., Lu et al. 2024a, 2024b; Fan et al. 2024; Liu et al. 2024); none of these citations is load-bearing for the central claim. The internal inconsistency that DeepSeek-R1 is described as an over-generous scorer in Sec. 4.2 yet used as an evaluator in Sec. 4.3, and the absence of inter-annotator agreement statistics, are validity/correctness concerns for the evaluations, not circular derivation steps. No prediction in the paper reduces by construction to its inputs.

High-quality math datasets are crucial for advancing the reasoning abilities of large language models (LLMs). However, existing datasets often suffer from three key issues: outdated and insufficient challenging content, neglecting human-like reasoning, and limited reliability due to single-LLM generation. To address these, we introduce STORM-BORN, an ultra-challenging dataset of mathematical derivations sourced from cutting-edge academic papers, which includes dense human-like approximations and heuristic cues. To ensure the reliability and quality, we propose a novel human-in-the-loop, multi-agent data generation framework, integrating reasoning-dense filters, multi-agent collaboration, and human mathematicians' evaluations. We curated a set of 2,000 synthetic samples and deliberately selected the 100 most difficult problems. Even most advanced models like GPT-o1 solved fewer than 5% of them. Fine-tuning on STORM-BORN boosts accuracy by 7.84% (LLaMA3-8B) and 9.12% (Qwen2.5-7B). As AI approaches mathematician-level reasoning, STORM-BORN provides both a high-difficulty benchmark and a human-like reasoning training resource. Our code and dataset are publicly available at https://github.com/lwhere/STORM-BORN.
