Convert academic papers into benchmark tasks for evaluating AI agents.

Paper2Bench

Convert academic papers into benchmark tasks for evaluating AI coding agents.

Paper2Bench offers two complementary workflows:

1. Core pipeline — a reproducible task per paper: extract what the paper used (models, datasets, budget), hand it to an agent, and score the agent's conclusion against the paper's.
2. Benchmark-variant generator — turn a paper into a family of new research problems (perturbations, ablations, future-work tasks) that test whether an agent can transfer the paper's logic to new settings.

Both workflows auto-detect the paper's archetype (llm_evaluation / novel_architecture / empirical_study) and route extraction through a matching prompt and template — so papers like CGCNN or SchNet don't get shoehorned into an LLM-evaluation schema.

Install

For development:

git clone https://github.com/AbhayAnandUCSD/Paper2Bench.git
cd Paper2Bench
pip install -e .

Or install directly from GitHub:

pip install git+https://github.com/AbhayAnandUCSD/Paper2Bench.git@v0.3.0

If you want to use Claude models, install the optional anthropic extra:

pip install "paper2bench[anthropic] @ git+https://github.com/AbhayAnandUCSD/Paper2Bench.git@v0.3.0"

Requires Python 3.10+. Set at least one provider key (both may coexist in a .env file):

export OPENAI_API_KEY=sk-...           # required for gpt-* / o-* models
export ANTHROPIC_API_KEY=sk-ant-...    # required for claude-* models

Provider selection is automatic based on the model name:

• gpt-*, o1-*, o3-*, o4-* → OpenAI
• claude-*, anthropic/claude-* → Anthropic

So --model claude-opus-4-6 just works if ANTHROPIC_API_KEY is set and the anthropic extra is installed. The default model is gpt-4o. Each stage that accepts --model (or --agent-model / --eval-model) can be pointed at either provider independently.

Note on Claude + --split-rqs: a single paper's run makes ~6 LLM calls per RQ, each with ~45k input tokens. Lower Anthropic tiers (30k input-tokens/min) will hit rate limits on papers with many RQs. Workarounds: run one RQ at a time via --research-question "..." instead of --split-rqs, or use OpenAI for batch runs.

Python SDK

The pipeline is also importable as a library — useful when you want to feed Paper2Bench programmatically rather than via the CLI:

import paper2bench

result = paper2bench.run(
    pdf="paper.pdf",
    research_question="Does X improve Y?",
    api_key="sk-...",                  # or rely on OPENAI_API_KEY / ANTHROPIC_API_KEY env vars
    output_dir="./output",
)

print(result.paper_type)               # auto-classified, or pass paper_type=... to override
print(result.instruction_path)         # ./output/tasks/<task_id>/instruction.txt
print(result.instruction_gt_path)      # ground-truth experimental plan
print(result.config)                   # parsed task_config.yaml as dict

Stage functions (parse_paper_to_tree, classify_paper, extract_yaml_from_pdf, render_instruction, generate_supplementary_plan, build_instruction_gt, verify_instruction_gt, extract_paper_spec, generate_variants, chat) are also importable from paper2bench for power users who want to compose the pipeline manually.

Quick start

One-shot benchmark from an arXiv query:

paper2bench run \
  --task-id reversal_curse \
  --query "The Reversal Curse Berglund" \
  --research-question "If an LLM is fine-tuned on 'A is B,' does it learn 'B is A'?" \
  --output-dir ./output/ \
  --auto

--auto re-ranks arXiv results by title similarity and picks the top match if it scores at or above --min-similarity (default 0.4). If your query phrasing diverges from the canonical title and --auto aborts, pass a lower threshold like --min-similarity 0.3 — the abort message will tell you what value to try.

Generate a family of variant benchmarks from an existing PDF:

paper2bench specextract --pdf paper.pdf -o spec.json
paper2bench generate    --spec spec.json --pdf paper.pdf -o ./variants/

---

Pipelines at a glance

Core pipeline — paper → single benchmark task:

Paper title/author
  → paper2bench download   → PDF
  → paper2bench parse      → problem tree JSON
  → paper2bench classify   → paper_type (auto)
  → paper2bench extract    → task_config.yaml
  → paper2bench render     → instruction.txt
  → paper2bench plan       → instruction_gt.txt   (ground-truth plan)
  → paper2bench verify     → F1 check             (optional)

Benchmark-variant generator — paper → family of variant tasks:

PDF
  → paper2bench specextract → paper_spec.json  (7-component spec)
  → paper2bench generate    → variants/<id>/{instruction.txt, task_config.yaml, metadata.json}

The two workflows are independent — you can use either on its own.

--verify	After generating instruction_gt.txt, run an agent with it and check F1 ≥ 80
--template PATH	Use a custom instruction template
--model MODEL	Change the LLM (default gpt-4o)

Paper types and auto-classification

Every paper is auto-classified into one of three archetypes; the type drives both the extraction prompt and the instruction template. Pass --paper-type anywhere to override.

Type	When it fires	Schema highlights	Template
llm_evaluation	Paper evaluates existing models on a task (e.g. Lost in the Middle, Chain-of-Thought)	models.api, models.huggingface, datasets	default.txt
novel_architecture	Paper introduces a new model / method (e.g. CGCNN, SchNet, Transformer)	proposed_method, baselines, reference_implementation	novel_architecture.txt
empirical_study	Observational / meta-study, no new model	study_type, data_sources, analytical_tools	empirical_study.txt

All three schemas also include:

• references — author-year citations get their own field so they aren't mis-extracted as fake synthetic datasets.
• HuggingFace loader validation — any source: huggingface loader is checked against the Hub; missing repos are demoted to source: unknown (bypass with --skip-hf-validation).

Verification (F1 gate)

paper2bench verify runs a coding agent with instruction_gt.txt, extracts its final conclusion, decomposes both the conclusion and a paper-derived reference answer into atomic claims, and computes claim-level precision / recall / F1. The task passes if F1 ≥ 80.

Verification is opt-in and not suitable for papers whose experiments can't be executed in a Python sandbox.

paper2bench verify \
  --instruction-gt ./tasks/my_task/instruction_gt.txt \
  --pdf ./papers/my_paper.pdf \
  --data-dir ./tasks/my_task/data \
  --agent-model gpt-4o \
  --eval-model gpt-4o

Splitting papers with multiple research questions

Pass --split-rqs on run to emit a separate benchmark task per research question found in the parsed problem tree. Each sub-task lands in tasks/<task_id>_rqN/ with its own config, instruction, and instruction_gt.

paper2bench run --task-id my_task --pdf paper.pdf --split-rqs

Benchmark-variant generator

For evaluating transfer rather than reproduction, specextract + generate turn a paper into a family of new research problems:

• Perturbations — new dataset, tighter budget, different metric, shifted domain
• Ablation-derived — does the key component still matter under a shift? Which fails first?
• Future-work-derived — bounded instantiations of the paper's stated limitations

Each variant includes an automated leakage check (direct-answer / method / statistical leak) so instructions that accidentally reveal the paper's answer get flagged.

# Extract the 7-component paper specification
paper2bench specextract --pdf paper.pdf -o spec.json

# Generate a family of variants (auto-classifies paper type; override with --paper-type)
paper2bench generate --spec spec.json --pdf paper.pdf -o ./variants/

Each variant directory contains:

• instruction.txt — a detailed research instruction, same format as the core pipeline's instruction.txt (research question + models/method + datasets with loaders + budget + constraints), rendered through the paper-type-aware template.
• task_config.yaml — the resource spec that was rendered into the instruction.
• metadata.json — transformation type, difficulty, rationale, curator-only expected outcome hint, and leakage-check verdict.

Because the generator reuses the paper-type branching, variants of a materials-science paper tell the agent "implement the method yourself" while variants of an LLM-evaluation paper list concrete API model IDs and HuggingFace loaders.

Custom templates

Pass --template to render (or run) to use your own template:

paper2bench render --config task.yaml --template my_template.txt -o instruction.txt

Template placeholders: {research_question}, {models_section}, {datasets_section}, {budget_per_model}, {constraints_section}.

---

Worked examples

Three papers run end-to-end through the core pipeline, showing how the classifier routes each one to a different schema. Each example shows the full rendered instruction.txt (what the agent actually sees) and the extracted task_config.yaml that produced it.

---

Lost in the Middle (NLP / LLM)

Classified llm_evaluation (high confidence). The LLM-evaluation template lists concrete API + HuggingFace models, dataset loaders, and budget — the agent is expected to evaluate these models, not implement a new one.

CGCNN (materials science)

Classified novel_architecture (high confidence). The template tells the agent to implement the method from scratch — not call a library that bundles the paper's code — and hands it the method's key components, baselines, and a reference repo hint.

Rendered instruction.txt

You are a research agent. Conduct research about the question: "Can graph convolutional neural networks predict material properties directly from crystal structure?"

Your central task is to **implement a proposed method from scratch** and evaluate whether it answers the research question. Do NOT import a library that bundles the paper's exact code; the benchmark value comes from your own implementation.

Proposed method to implement:
- Crystal Graph Convolutional Neural Networks (CGCNN): CGCNN is a framework that represents crystal structures as graphs, where nodes represent atoms and edges represent bonds. A convolutional neural network is applied to these graphs to predict material properties directly from the crystal structure, achieving accuracy comparable to DFT calculations while providing interpretability by extracting contributions from local chemical environments.
  - Component: Crystal graph representation with nodes as atoms and edges as bonds
  - Component: Graph convolutional layers to update atom feature vectors
  - Component: Pooling layers to aggregate features into a crystal-level representation
  - Component: Fully-connected layers for property prediction
- Baseline for comparison: DFT calculations
- Reference hint: https://github.com/txie-93/cgcnn

SchNet (quantum chemistry)

Classified novel_architecture (high confidence). The HF-loader validator rejected all three claimed dataset paths (qm9, md17, iso17) as non-existent on the Hub — they were demoted to source: unknown so the agent knows to locate the data itself rather than waste time on hallucinated loaders.

Rendered instruction.txt

You are a research agent. Conduct research about the question: "Can continuous-filter convolutional neural networks accurately model quantum-mechanical interactions in molecules?"

Your central task is to **implement a proposed method from scratch** and evaluate whether it answers the research question. Do NOT import a library that bundles the paper's exact code; the benchmark value comes from your own implementation.

Proposed method to implement:
- SchNet: SchNet is a deep learning architecture that uses continuous-filter convolutional layers to model quantum interactions in molecules. It respects essential quantum-chemical constraints, providing rotationally invariant energy predictions and rotationally equivariant force predictions. SchNet is designed to handle molecules with arbitrary atomic positions, ensuring a smooth potential energy surface and energy-conserving force fields.
  - Component: Continuous-filter convolutional layers
  - Component: Rotationally invariant energy prediction

Before paper-type branching, CGCNN produced empty model lists and SchNet hallucinated meta-llama/Llama-3.1-8B-Instruct as a "model for the task" — neither paper has anything to do with LLMs.

Example variant (from the benchmark generator)

Running specextract + generate on CGCNN produced six variants across perturbation / ablation / future-work. Here is one — a perturbation that changes the empirical setting while preserving the paper's core hypothesis. Note the detailed instruction.txt uses the same novel_architecture template as the core pipeline, so the agent is still told to "implement the method yourself":

Variant: cgcnn_benchmark_elastic_properties — perturbation, medium difficulty, leakage-clean

How it works

Core pipeline

1. Download — arXiv search by title/author with exponential backoff on HTTP 429.
2. Parse — LLM decomposes the paper into a 3-level problem tree (root → research questions → experiments).
3. Classify — a small LLM call over the paper's head tags it as llm_evaluation, novel_architecture, or empirical_study. Drives everything downstream.
4. Extract — one of three type-specific prompts pulls a structured resource spec (models / method / datasets / budget / constraints) into YAML. HuggingFace loaders are checked against the Hub; hallucinated IDs are demoted to source: unknown. Author-year citations go into a separate references field.
5. Render — a type-aware template converts the YAML into a standardized instruction.txt. Deliberately withholds the paper's methodology so the agent must design experiments.
6. Plan — LLM reads the paper again and writes detailed experimental procedures as a supplementary plan, combined with the base instruction to produce instruction_gt.txt (for evaluation, not for the agent).
7. Verify (optional) — runs a coding agent against instruction_gt.txt, then scores the agent's conclusion with claim-level precision / recall / F1 (adapted from FIRE-Bench's RAGChecker evaluator).

Benchmark-variant generator

1. specextract — distills the paper into a 7-component specification: scientific question, method (summary + components), claims, evaluation protocol, assumptions, ablation structure, future work.
2. generate — given the spec, emits a JSON family of 6–12 instances across three transformation strategies (perturbation / ablation / future-work), each with a paper-type-matching task_config. Each config is rendered into a detailed instruction.txt via the same render_instruction function used by the core pipeline, then audited by an LLM judge for three leakage types.
