Large Language Models Achieve Gold Medal Performance at the International Olympiad on Astronomy & Astrophysics (IOAA) (2510.05016v2)
Abstract: While task-specific demonstrations show early success in applying LLMs to automate some astronomical research tasks, they only provide incomplete views of all necessary capabilities in solving astronomy problems, calling for more thorough understanding of LLMs' strengths and limitations. So far, existing benchmarks and evaluations focus on simple question-answering that primarily tests astronomical knowledge and fails to evaluate the complex reasoning required for real-world research in the discipline. Here, we address this gap by systematically benchmarking five state-of-the-art LLMs on the International Olympiad on Astronomy and Astrophysics (IOAA) exams, which are designed to examine deep conceptual understanding, multi-step derivations, and multimodal analysis. With average scores of 85.6% and 84.2%, Gemini 2.5 Pro and GPT-5 (the two top-performing models) not only achieve gold medal level performance but also rank in the top two among ~200-300 participants in all four IOAA theory exams evaluated (2022-2025). In comparison, results on the data analysis exams show more divergence. GPT-5 still excels in the exams with an 88.5% average score, ranking top 10 among the participants in the four most recent IOAAs, while other models' performances drop to 48-76%. Furthermore, our in-depth error analysis underscores conceptual reasoning, geometric reasoning, and spatial visualization (52-79% accuracy) as consistent weaknesses among all LLMs. Hence, although LLMs approach peak human performance in theory exams, critical gaps must be addressed before they can serve as autonomous research agents in astronomy.
Summary
- The paper shows that models like GPT-5 and Gemini 2.5 Pro achieved gold medal performance on both theory and data analysis exams, often surpassing top human competitors.
- The methodology used standardized LaTeX prompts with expert grading to objectively assess multi-step derivations, multimodal analysis, and astronomical problem-solving.
- The findings highlight LLM strengths in scientific reasoning alongside notable limitations in geometric/spatial and multimodal integration, guiding future model enhancements.
LLMs Achieve Gold Medal Performance at the International Olympiad on Astronomy & Astrophysics (IOAA)
Introduction and Motivation
This paper presents a systematic evaluation of five state-of-the-art LLMs—GPT-5, Gemini 2.5 Pro, OpenAI o3, Claude Opus 4.1, and Claude Sonnet 4—on the International Olympiad on Astronomy and Astrophysics (IOAA) exams from 2022 to 2025. Unlike prior benchmarks that focus on simple question-answering, the IOAA exams probe deep conceptual understanding, multi-step derivations, and multimodal analysis, providing a rigorous testbed for assessing LLMs' scientific reasoning capabilities in astronomy and astrophysics.
The IOAA consists of theory, data analysis, and observational exams, with the latter excluded due to the digital nature of LLMs. The evaluation covers 49 theory and 8 data analysis problems, spanning a wide range of topics and difficulty levels. The paper aims to elucidate both the strengths and limitations of LLMs in complex astronomical problem-solving, with implications for their deployment as autonomous research agents.
Experimental Design and Evaluation Protocol
All models were prompted with standardized LaTeX-formatted problems, embedded figures, and a reference sheet of constants and formulas, mirroring the conditions faced by human IOAA participants. Solutions were required to be step-by-step, fully justified, and rendered in LaTeX, including plot generation via tikzpicture and pgfplots. Grading was performed independently by two IOAA experts using official rubrics, with consensus resolution for discrepancies.
The dataset includes both historical (2022–2024) and contamination-free (2025) problems, enabling assessment of potential training data leakage. Difficulty levels were assigned based on median human scores, ensuring objective calibration across Easy, Medium, Hard, and Extra Hard categories.
Performance Analysis: Theory and Data Analysis Exams
Theory Exams
GPT-5 and Gemini 2.5 Pro consistently achieve gold medal performance, with average scores of 84.2% and 85.6%, respectively, ranking in the top two among 200–300 human participants in all four years. Notably, these models outperform the best human competitors in several instances. OpenAI o3 follows with 77.5%, while Claude models lag at 64.7% (Opus 4.1) and 60.6% (Sonnet 4).
Performance is robust across difficulty levels, though GPT-5 exhibits higher scores on hard questions, attributed to dataset size and occasional significant errors on easier problems. All models maintain gold-level rankings except Claude Sonnet 4, which drops to silver in 2023.
Data Analysis Exams
GPT-5 demonstrates exceptional multimodal capabilities, scoring 88.5% and ranking in the top 10 among human participants. Gemini 2.5 Pro also maintains strong performance (75.7%), but other models show marked declines (OpenAI o3: 67.7%, Claude Opus 4.1: 54.8%, Claude Sonnet 4: 47.9%). The variance is attributed to the heavy reliance on plot interpretation and data visualization, with GPT-5 exhibiting superior error rates in these domains.
Error Analysis and Failure Modes
A detailed error analysis categorizes mistakes into conceptual, geometric/spatial, calculation, plot/image reading, plotting, notation, approximation, and derivation errors.
Figure 1: Distribution of points lost by error type across all models for IOAA theory and data analysis exams, highlighting the dominance of conceptual and geometric/spatial errors in theory and plotting/image reading errors in data analysis.
Theory Exams: Geometric and Conceptual Reasoning
The most prevalent errors are conceptual (misapplied formulas, flawed reasoning) and geometric/spatial (visualization, spherical trigonometry, coordinate transformations), together accounting for 60–70% of total points lost. All models except Gemini 2.5 Pro and GPT-5 show pronounced weaknesses in geometric reasoning, particularly in the 2024 exam where such problems dominate.
Qualitative analysis reveals fundamental issues: models often violate basic geometric principles, misinterpret spherical trigonometry, and confuse temporal reference frames (e.g., tropical vs. sidereal years). The inability to visualize or sketch spatial configurations during reasoning is a critical limitation, suggesting the need for integrated visual sketchpad architectures.

Figure 3: Detector configuration with , exemplifying basic geometric tasks that challenge most LLMs.
Data Analysis Exams: Multimodal and Computational Errors
In data analysis, errors are more evenly distributed, with plotting and plot/image reading as the dominant categories for less capable models. Calculation errors are also significant due to the multi-step nature of data extraction and visualization tasks. Conceptual and geometric errors are less prominent, reflecting the shift in skill requirements.

Figure 5: Multiple blackbody radiation curves requiring identification of correct temperature relationships, highlighting the challenge of integrating theoretical knowledge with visual analysis.
Figure 6: Scale factor evolution plot requiring value extraction for black hole mass calculations, demonstrating the complexity of multimodal reasoning in data analysis.
Comparison to Human Performance
LLMs not only achieve gold medal thresholds but also frequently surpass the best human competitors in both theory and data analysis exams. The ranking analysis confirms that GPT-5 and Gemini 2.5 Pro consistently place first or second, with OpenAI o3 also outperforming top students in select years. Claude models, while competitive, do not match the top-tier performance.
Implications and Future Directions
The results indicate that LLMs possess genuine scientific reasoning capabilities, rivaling talented human competitors in astronomy and astrophysics. They are suitable as AI co-scientists for formula verification, parameter exploration, and concept cross-checking. However, critical gaps remain in geometric/spatial reasoning, multimodal integration, and mathematical rigor, precluding their deployment as fully autonomous research agents.
To address these limitations, future work should focus on:
- Visual Sketchpad Integration: Enabling models to visualize and manipulate spatial representations during reasoning.
- Multimodal Data Synthesis: Large-scale generation of visual question answering examples to improve chart and image understanding.
- Mathematical Reasoning Transparency: Training for complete derivations and stepwise explanations, reducing answer-focused biases.
- Domain-Specific Fine-Tuning: Leveraging astronomy's collaborative research culture and vast data resources for targeted model improvement.
Conclusion
This paper provides a comprehensive benchmark of LLMs on the IOAA, revealing near-human and often superhuman performance in complex astronomical problem-solving. While LLMs are poised to accelerate research as valuable partners, substantial architectural and training advances are required to overcome persistent weaknesses in geometric, spatial, and multimodal reasoning. The IOAA benchmark sets a new standard for evaluating scientific AI agents, guiding future developments toward robust, autonomous research capabilities in astronomy and beyond.

What is this paper about?
This paper tests how well powerful AI LLMs can solve tough astronomy and physics problems from a real international competition, the International Olympiad on Astronomy and Astrophysics (IOAA). The main idea is to see whether these AIs can think through multi-step science problems like top students do, not just answer simple quiz questions.
What questions did the researchers ask?
The researchers focused on a few simple questions:
- Can today’s AI models solve IOAA problems at a medal level, like top human students?
- Which kinds of problems are they good at, and which kinds still trip them up?
- Do they handle not only math and concepts, but also real data, graphs, and diagrams?
- Are the results reliable and not just memorized from the internet?
How did they test the AIs?
First, a quick note: IOAA is like the “Olympics” for high school astronomy. It has three parts:
- Theory: deep science questions that need multi-step reasoning and math.
- Data Analysis: working with real astronomy data, charts, and plots.
- Observation: using instruments and the night sky (not used here, because AIs can’t point telescopes).
What the researchers did:
- They collected four years of IOAA problems (2022–2025): 49 theory questions and 8 data analysis tasks of different difficulty levels.
- They tested five top AI models: GPT-5, Gemini 2.5 Pro, OpenAI o3, Claude Opus 4.1, and Claude Sonnet 4.
- Each AI got the exact same question text and any figures. They were asked to show their work step by step, like students do.
- Two IOAA experts graded the AI answers using the official scoring rules, discussed any differences, and agreed on final scores.
- To check against memorization, they paid special attention to the 2025 exam (given after the models’ knowledge cutoffs), which serves as a “fresh” test. The AIs performed similarly there, suggesting results weren’t just from memorized answers.
A few terms in everyday language:
- LaTeX: a way to neatly write math and science solutions (like a very clean digital “handwriting” for equations).
- Multimodal: handling not just words, but also images, charts, and plots.
- Spherical trigonometry: geometry on a sphere (like Earth’s surface), used for things on the sky dome, not flat paper.
What did they find?
Big picture:
- On the theory exams, GPT-5 and Gemini 2.5 Pro scored around 84–86% on average—good enough for gold medals and even top-2 rankings among roughly 200–300 human participants each year.
- On the data analysis exams, GPT-5 did extremely well (about 88.5% average, often top 10 among humans). Other models dropped more (roughly 48–76%), especially when they had to read or make plots.
More details on strengths and weaknesses:
- Strong: Physics and math reasoning. When problems were mostly calculations and scientific concepts (like astrophysical formulas and estimates), the top AIs did very well.
- Weak: Geometry and spatial thinking. Problems that need you to picture the sky, rotate coordinates, or do math on a sphere were much harder. For example, picking the right angles on the “celestial sphere,” or understanding time systems (tropical vs. sidereal year), often led to mistakes.
- Mixed: Working with charts and plots. GPT-5 read and made plots more accurately than the others. For some models, plotting and reading figures was the biggest source of errors.
- Most common errors: Conceptual misunderstandings (using the wrong idea or formula) and geometric/spatial mistakes (trouble visualizing shapes in 3D or on a sphere) caused most lost points. Simple arithmetic slips were less important overall in theory, but showed up more in data analysis because there are many small calculations.
Why this matters:
- The best AIs now solve difficult, multi-step science problems at a level that rivals top human competitors. That’s a big leap beyond simple quiz-style tests.
What does this mean for the future?
Simple takeaways:
- Helpful co-scientists: These AIs can already help students and researchers check equations, explore ideas, and reason through many astronomy problems.
- Not fully independent yet: They still struggle with visual-spatial tasks, spherical geometry, and some chart understanding. Human checking is still important—especially for diagrams, time systems, and geometry-heavy steps.
- How to improve AIs: Giving them better “visual thinking” tools (like a sketchpad to draw and reason with shapes), training them more on reading and creating scientific plots, and practicing with realistic astronomy data should make them stronger.
- Bigger picture: As these models get better at spatial and multimodal reasoning, they could speed up real discoveries in astronomy by handling more of the careful, step-by-step work scientists do.
In short, today’s AIs can earn gold medals on tough astronomy theory exams and do very well on data tasks—especially the top models—yet they still need to get better at thinking in pictures (space, angles, and spheres) before they can act like fully independent astronomy researchers.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a single, consolidated list of what remains missing, uncertain, or unexplored in the paper, framed concretely so future work can act on it.
- Evaluation excludes the IOAA observation exam; design and assess simulated observation tasks (e.g., star-chart navigation, telescope pointing/calibration, real-time sky conditions) to cover hands-on skills central to astronomy.
- Generalization to real research workflows is untested; benchmark LLMs on end-to-end tasks using real astronomical data products (FITS images, spectra, catalogs), code execution (e.g., AstroPy), and archive queries (e.g., SDSS, Gaia) within tool-augmented agent settings.
- Multimodal reasoning is only probed via static exam figures and LaTeX plotting; assess performance on richer modalities (FITS visualization, spectral line identification, multi-instrument cross-matching, multi-band photometry) and interactive 3D geometry/visualization tasks.
- Data contamination for 2022–2024 is inferred to be minimal but not audited; perform formal contamination detection (e.g., web-scale search for overlaps, model “copying” checks, nearest-neighbor retrieval tests) and sensitivity analyses to quantify its effect on scores.
- Single-shot evaluation masks variance; measure performance stability across multiple runs/seeds and under self-verification/reflection loops to estimate reliability and best-of-N versus first-pass behavior.
- Prompting effects are not studied; run ablations comparing different prompt styles (concise vs. verbose, tool-use directives, hidden vs. explicit chain-of-thought) and quantify prompt sensitivity on scoring and error types.
- Tool augmentation is restricted (e.g., no calculators/Python during solving); compare baseline to tool-enabled agents (symbolic math, numerical solvers, plotting libraries) to isolate the gains from computation and external tools.
- Grading reliability is not quantified; report inter-rater agreement (e.g., Cohen’s κ) and release a detailed rubric-to-score mapping for each problem to enable independent verification and meta-evaluation.
- Potential verbosity-to-partial-credit bias is unaddressed; test whether longer, highly verbose solutions systematically earn more partial credit than concise correct steps, and normalize grading to control for verbosity.
- Human comparison and medal rankings are inferred from theory/data-analysis components only; evaluate how excluding the observation component alters rank estimates, or develop methods to approximate observation scores for a fairer holistic comparison.
- Statistical rigor on year-to-year comparability is limited; apply formal tests (e.g., mixed-effects models) to separate model effects from annual variation in topic mix, style, and difficulty, and reweight scores by topic distribution.
- Dataset scale is small (49 theory, 8 data analysis problems across four years); expand coverage with additional IOAA years and construct validated, IOAA-like synthetic problems to increase statistical power, especially for data analysis tasks.
- Error taxonomy lacks reproducibility measures; formally define each error category, release annotated errors per problem/model, and measure inter-annotator agreement to make the taxonomy reusable and comparable across studies.
- Calibration and uncertainty are not assessed; require models to provide confidence estimates, then evaluate calibration (e.g., Brier score, ECE) and whether confidence correlates with correctness across problem types.
- Robustness to noisy/incomplete/problematic inputs is untested; introduce realistic perturbations (typos, missing constants, conflicting figures, ambiguous phrasing) to quantify resilience and failure modes under non-ideal conditions.
- Spatial reasoning interventions are not evaluated; test sketchpad/drawing tools, geometric solvers, and explicit diagram generation pipelines to quantify their impact on spherical trigonometry and celestial geometry tasks.
- Targeted deficits (sidereal vs. tropical years, calendar vs. tropical year equivalence, great-circle geometry) are observed but not isolated; build focused micro-benchmarks to measure mastery of timekeeping systems and spherical trigonometry independently of broader context.
- LaTeX plotting (tikz/pgfplots) is atypical for astronomical practice; compare performance using standard scientific plotting (matplotlib, seaborn) and dataframes to see if plotting errors are format-specific rather than reasoning-related.
- Multilingual capability (common in international olympiads) is not evaluated; assess performance on problems in multiple languages and mixed-language settings to test robustness and accessibility.
- Context-length and file-handling constraints are not probed; evaluate tasks requiring long tables, external file ingestion (FITS, CSV), and iterative refinement across multi-turn dialogues to reflect realistic data analysis workflows.
- Latency, cost, and throughput are not reported; measure time-to-solution, API costs, and computational budget to assess practical viability compared to human effort in competitive or research settings.
- Model versioning and reproducibility are under-specified; log exact model builds/dates and re-run a subset after provider updates to quantify performance drift and ensure longitudinal reproducibility.
- Retrieval-augmented reasoning is not examined; compare closed-book solving to retrieval from vetted astronomical references (textbooks, papers, catalog docs) to determine whether knowledge access mitigates conceptual errors.
- Release of full artifacts is partial; publish raw model outputs, compiled PDFs, per-step rubric scores, and error annotations (with licenses) to enable third-party replication and meta-analysis.
