Evaluating Large Language Models in Scientific Discovery (2512.15567v1)
Abstract: LLMs are increasingly applied to scientific research, yet prevailing science benchmarks probe decontextualized knowledge and overlook the iterative reasoning, hypothesis generation, and observation interpretation that drive scientific discovery. We introduce a scenario-grounded benchmark that evaluates LLMs across biology, chemistry, materials, and physics, where domain experts define research projects of genuine interest and decompose them into modular research scenarios from which vetted questions are sampled. The framework assesses models at two levels: (i) question-level accuracy on scenario-tied items and (ii) project-level performance, where models must propose testable hypotheses, design simulations or experiments, and interpret results. Applying this two-phase scientific discovery evaluation (SDE) framework to state-of-the-art LLMs reveals a consistent performance gap relative to general science benchmarks, diminishing return of scaling up model sizes and reasoning, and systematic weaknesses shared across top-tier models from different providers. Large performance variation in research scenarios leads to changing choices of the best performing model on scientific discovery projects evaluated, suggesting all current LLMs are distant to general scientific "superintelligence". Nevertheless, LLMs already demonstrate promise in a great variety of scientific discovery projects, including cases where constituent scenario scores are low, highlighting the role of guided exploration and serendipity in discovery. This SDE framework offers a reproducible benchmark for discovery-relevant evaluation of LLMs and charts practical paths to advance their development toward scientific discovery.

Evaluating LLMs in Scientific Discovery
Overview: From Static Benchmarks to Scenario-Grounded Evaluation
LLMs are increasingly deployed in scientific research workflows, encompassing stages from literature triage to hypothesis generation, simulation, code synthesis, and autonomous experimentation. Despite advances in coding, mathematics, and basic science Q&A challenge sets, prevailing benchmarks have remained largely decontextualized, focusing on quiz-like formats without measuring iterative reasoning, hypothesis refinement, and the integration of imperfect evidence that typify genuine scientific discovery. This paper introduces the Scientific Discovery Evaluation (SDE) framework, which evaluates LLMs on modular, expert-curated research scenarios and end-to-end project-level discovery tasks across biology, chemistry, materials, and physics domains.

SDE Framework: Methodological Design and Scope
The SDE benchmark is structured hierarchically. Domain experts define projects of concrete scientific interest, which are decomposed into modular research scenarios recurring in real workflows. Each scenario is supported by vetted question sets, totaling 1,125 questions spanning 43 scenarios, designed to reflect authentic challenges in biology, chemistry, materials, and physics. Evaluation comprises two axes: (1) question-level accuracy on scenario-grounded items and (2) project-level performance, requiring models to generate hypotheses, design experiments or simulations, and interpret results iteratively.
Question-Level Evaluations: Accuracy, Scaling, and Failure Modes
Performance of LLMs varies sharply across scenarios and models, with distinct flagship models excelling per domain. Notably, scores on SDE are consistently lower than on general science QA (e.g., GPQA-Diamond, MMMU), revealing a persistent gap between decontextualized trivia and discovery-relevant reasoning.
Figure 2: Cross-model, cross-domain scenario accuracies; SDE exposes greater difficulty and performance spread than general benchmarks.
Scaling and explicit reasoning (multi-step derivation, evidence integration) yield accuracy improvements but demonstrate diminishing returns; gains from increased model size or test-time compute saturate on SDE tasks for recent frontier models (gpt-5, grok-4, deepseek-R1, claude-sonnet-4.5).
Figure 3: Scaling and reasoning effort for gpt-5 series; monotonic but saturating domain accuracy for both model size and reasoning depth.
Moreover, top models display strong error correlations and concordant failure modes—shared weaknesses across most difficult scenarios (e.g., NMR structure elucidation, quantum property prediction), possibly due to convergent pretraining corpora and objectives. Ensemble strategies deliver limited gains on such scenarios.
Project-Level Evaluations: End-to-End Scientific Discovery
SDE includes eight discovery projects emulating authentic loops: hypothesis proposal, experiment/simulation, observation, and hypothesis refinement, integrating domain-specific computational oracles and iterative evolutionary search strategies. Projects span retrosynthesis, molecule optimization, protein engineering, TMC optimization, crystal structure generation, gene editing, symbolic regression, and Ising model minimization.
Figure 4: Project-level evaluation schematic and results; normalized single-metric scores across four flagship LLMs in diverse discovery tasks.
On quantifiable projects (e.g., protein optimization, TMC polarisability maximization), LLMs with enhanced reasoning capabilities demonstrate faster convergence and superior performance, rivaling or outperforming traditional evolutionary baselines, especially for high-dimensional combinatorial spaces. For instance, deepseek-R1 achieves the highest average Top-1 score in protein optimization ($0.8713$), improving over evolutionary baselines.
Figure 5: Protein sequence optimization: bar chart and convergence curves highlight optimization quality and sample efficiency across LLMs.
In symbolic regression, LLMs (gpt-5, deepseek-R1) outperform PySR, finding governing equations with higher accuracy and lower mean squared errors, both in-distribution and OOD—a significant deviation from local search paradigms.
Figure 6: Symbolic regression convergence demonstrating LLM-guided iterative discovery surpasses evolutionary search baselines.
Conversely, projects demanding rigorous long-horizon planning (retrosynthesis) or validity checks pose challenges, with model performance lagging behind tailored search algorithms or earlier LLM releases, and older models (gpt-4o) sometimes outperforming successors.
Scenario-to-Project Performance Transfer and Model Robustness
While scenario-level mastery is generally predictive of downstream project success, exceptions occur. Models demonstrate notable serendipity: e.g., despite low scenario accuracy in TMC property prediction, reasoning LLMs efficiently navigate optimization in the full 1.37M TMC space. However, high scenario scores do not guarantee project-level proficiency—failures in molecule or reaction validity thwart advanced retrosynthesis.
No model uniformly excels across all projects; performance leadership rotates, accentuating the need for balanced cross-scenario proficiency. Strong reasoning enhancements fail to deliver in some tasks, and pretraining corpus effects are less decisive in complex multi-step discoveries than simple Q&A or property estimation.
Cross-Model Patterns: Correlation, Consensus, and Difficult Questions
Top models' accuracies and rankings display substantial domain-wise and scenario-wise correlation, particularly in chemistry and physics (pairwise Pearson/Spearman ). Question-level error concordance (SDE-hard set) confirms systematic common weaknesses, challenging ensemble or majority-voting approaches and underscoring the need for targeted data and objective diversification.
Figure 7: Pairwise accuracy correlations among flagship models, colored by domain, underscore shared strengths and failure modes.
Consensus plots emphasize frequent co-failure and infrequent unique model successes on difficult questions, motivating investment in fundamentally novel model architectures and training regimens.

Implications, Limitations, and Future Directions
The SDE framework and results highlight key deficiencies in LLMs as autonomous scientific agents. Despite progress in QA and coding, models remain distant from "scientific superintelligence": reasoning and scaling advances plateau for discovery tasks, and systematic weaknesses persist. Performance transfer from scenario to project level is nuanced; capacity for hypothesis navigation and serendipitous search often trumps explicit structure-property knowledge.
To bridge capability gaps, future research should:
- Prioritize targeted training on scientific problem formulation, hypothesis refinement, and tool-use integration over indiscriminate scaling.
- Diversify pretraining data sources and inductive biases to mitigate cross-model error correlation and shared failure modes.
- Intensify reinforcement and evolution strategies specifically for scientific reasoning and long-horizon planning.
- Expand frameworks to incorporate additional disciplines (engineering, social sciences, earth sciences) and non-commercializable, reproducible open-weight model baselines.
Comprehensive benchmarking—evaluating not only answer correctness but also executable action, protocol refinement, and dynamic error propagation—will be crucial for advancing LLM readiness for autonomous and collaborative scientific discovery. Safety and domain-specific risk assessment, particularly in biological applications, remain ongoing concerns.
Conclusion
This paper establishes the Scientific Discovery Evaluation (SDE) framework, providing a scenario-grounded, project-integrated benchmark for LLMs in core scientific disciplines. The analysis reveals persistent gaps between conventional general science QA and discovery-relevant reasoning, diminished returns from scaling, convergent cross-model failure modes, and the nontrivial complexities of integrating LLMs into iterative research workflows. SDE offers a reproducible scaffold for charting practical paths toward next-generation models better equipped for multifaceted scientific discovery tasks, stimulating methodological innovation and systematic progress in AI for science.

Overview
This paper looks at how well “LLMs” (LLMs)—very smart chatbots like GPT, Claude, Grok, and DeepSeek—can actually help scientists make new discoveries. Instead of just testing them on random science quiz questions, the authors built a new way to test LLMs on real research tasks from biology, chemistry, materials science, and physics. They call this the Scientific Discovery Evaluation (SDE).
Key Questions the Paper Asks
- Can LLMs do more than answer science trivia? Can they handle the actual steps of discovery—like forming hypotheses, running tests, and learning from results?
- How do LLMs perform on realistic, context-rich science tasks compared to standard benchmarks (like math or general science quizzes)?
- Does “reasoning mode” (letting the model think step-by-step) or just making the model bigger always improve scientific discovery?
- Do different top models fail in the same ways?
- How do scores on small tasks (“scenarios”) connect to performance on full research projects?
How the Authors Tested the Models
They created a two-part evaluation that resembles the way scientists work in real life:
1) Scenario-Level (Question-Level) Tests
Think of “scenarios” as mini real-world tasks scientists face, like:
- Predicting what happens in a chemical reaction
- Reading lab data (like NMR or X-ray patterns) to figure out a molecule or crystal structure
- Judging if a drug candidate is likely to work in the body
- Estimating properties of materials (like battery electrolytes or metal complexes)
For each scenario, experts wrote or curated sets of questions (1,125 in total across 43 scenarios). These questions are tied directly to real research projects, not random trivia.
2) Project-Level (End-to-End) Tests
This mimics the “science fair project loop,” but at research level:
- The model proposes a testable hypothesis (an idea it wants to check)
- It designs or runs a simulation or experiment (using tools or code)
- It looks at the results and updates its hypothesis
They built a framework called “sde-harness” to run this loop across eight actual projects (e.g., optimizing special metal complexes, designing proteins, discovering equations for complex systems, and building new crystals). The model’s goal is to improve results over several rounds—like getting better at finding high-performing materials by learning from previous tries.
To keep it simple:
- Scenarios are the building blocks (small tasks)
- Projects are full builds (multi-step research challenges)
Main Findings
1) Real Research Tasks Are Harder Than Science Quizzes
- Top models score high on general benchmarks (like GPQA or MMMU) but noticeably lower on SDE’s scenario questions.
- Why? The SDE questions are grounded in real projects and require context, careful thinking, and interpreting imperfect evidence—just like real science.
2) Reasoning Helps—but Hits Limits
- Models that “think step-by-step” (like DeepSeek-R1) usually beat similar models without reasoning.
- However, simply turning up “reasoning” or making models bigger doesn’t keep giving big gains. Improvements start to flatten out on these discovery tasks.
3) Different Models Often Fail the Same Way
- Top models from different companies often make mistakes on the exact same hardest questions.
- This suggests they learned similar patterns from similar data, and share the same weaknesses.
4) A “Hard Mode” Shows Big Gaps
- The authors created SDE-hard: 86 of the toughest questions.
- All models scored very low, though a “pro” version of GPT did notably better on some especially tough items.
- There’s still a long way to go before LLMs become “superintelligent scientists.”
5) Project Results: Serendipity Matters
- In some projects, models did surprisingly well even if they didn’t score great on related scenarios.
- For example, multiple models quickly found metal complexes with very high polarizability from a huge search space, exploring trade-offs effectively.
- In symbolic regression (finding equations from data), models with reasoning improved faster and reached lower errors, showing strong “discover-and-refine” behavior.
- But models struggled with long, strict plans like multi-step chemical synthesis (retrosynthesis), often failing validity checks, and not always beating traditional tools.
6) No One Model Wins Everything
- Performance varies by project. One model might shine in materials, another in physics or chemistry.
- Overall, all current LLMs are far from a one-size-fits-all “scientific superintelligence.”
Why This Matters
- Real scientific discovery isn’t just answering facts; it’s about forming ideas, testing them, and learning from messy results. This new benchmark (SDE) tests exactly that.
- The findings show that:
- Models need training that focuses on scientific thinking (problem setup, hypothesis refinement), not just bigger models or longer “reasoning chains.”
- Better data and new training strategies are needed—especially ones that teach models to use tools (simulators, code, lab planners) and fix execution errors.
- Future improvements should target the actual loop of discovery: propose, test, interpret, and iterate.
Final Takeaway
LLMs are starting to help in real science—sometimes even finding good solutions quickly in large search spaces. But they still struggle with complex planning, strict validity checks, and truly hard questions tied to real research. The SDE framework gives scientists and developers a clearer, more honest way to measure progress and figure out what to improve next, nudging AI toward being a reliable partner in scientific discovery.
Knowledge Gaps
Below is a concise, action-oriented list of knowledge gaps, limitations, and open questions the paper leaves unresolved. Each point is intended to inform concrete follow-up studies or benchmark extensions.
- Domain coverage is incomplete: earth sciences, engineering, and social sciences are absent; how well does SDE generalize to these fields and cross-disciplinary problems (e.g., climate–materials, bio–policy)?
- Scenario selection bias: scenarios reflect contributors’ interests and practices; develop protocols for broader community sourcing, inter-rater agreement, and periodic rebalancing to ensure representativeness.
- Limited item counts per scenario (often ≥5 but still small) inflate variance; conduct power analyses, expand item pools, and report confidence intervals/bootstraps to quantify uncertainty.
- Possible pretraining contamination of templated or public-dataset-derived questions was not audited; implement overlap checks, provenance tracing, and contamination-adjusted baselines.
- API non-determinism and A/B testing hinder reproducibility; standardize with local open-weight baselines, fixed seeds, frozen tool/oracle versions, and published inference logs.
- Model coverage is narrow at project level (cost-limited) and focuses on a few frontier models; broaden to diverse open/closed models, ablate temperature/decoding settings, and report cost–accuracy trade-offs.
- Single optimization strategy and prompting protocol in project evaluations; compare Bayesian optimization, MCTS, bandits, active learning, and agentic frameworks with ablations over selection rules and iteration budgets.
- Tool-use capability is not directly benchmarked; add scenarios/projects that require planning, calling, and debugging domain tools (e.g., RDKit, VASP, LAMMPS), with metrics for execution success, recovery, and throughput.
- Question-to-project transfer is only qualitatively assessed; build predictive models that map scenario competencies to project success, and run controlled interventions to identify causal bottlenecks.
- Diminishing returns from scaling and test-time reasoning are observed but not explained; run controlled training studies (scientific RLHF/RLAIF, tool-integrated SFT, curricula on hypothesis formation) to quantify gains.
- Shared failure modes across providers are documented but not dissected; test whether diversifying pretraining corpora, objectives, or inductive biases reduces cross-model error correlation on SDE-hard.
- SDE-hard is small (86 items) and sensitive to “no response” handling; expand with more balanced, multi-domain, adversarially constructed items and define standardized abstention/calibration scoring.
- Evaluation metrics emphasize exact match/accuracy; add partial credit, rationale grading, calibration (ECE/Brier), abstention rewards, and uncertainty-aware scoring to better capture scientific decision quality.
- Multi-modality is limited; incorporate raw instrument/sensor modalities (e.g., NMR/IR/MS spectra, microscopy, PXRD images, time-series traces) instead of only textual/templated representations.
- Long-horizon planning and memory are not stress-tested; add projects requiring multi-stage plans, plan repair, persistent memory, and stateful tool invocation over tens to hundreds of steps.
- Safety and misuse risks (especially in biology) are acknowledged but not evaluated; integrate safety gates, red-team tasks, jailbreak resistance, and safe-abstention metrics into SDE and sde-harness.
- Real-world lab integration is missing; validate end-to-end closed-loop performance with autonomous labs, measuring experimental yield, time/cost, error handling, and physical constraints.
- Human-in-the-loop benefits are not quantified; run controlled user studies comparing human-alone, LLM-alone, and human+LLM conditions across projects and report net productivity/quality gains.
- Novelty and impact of discoveries are not measured; add bibliometric/novelty metrics (e.g., distance from literature), expert panel ratings, and downstream validation (e.g., simulation-to-experiment success).
- Interpretability and mechanistic understanding are unevaluated; score reasoning chains, mechanistic consistency, and causal hypothesis quality beyond final answers.
- Robustness and OOD generalization are lightly probed; systematically introduce domain shifts, noisy/contradictory evidence, and imperfect oracles to assess resilience and error recovery.
- Prompt sensitivity and protocol drift are underexplored; perform prompt ablations, instruction-tuning sensitivity analyses, and standardize prompt/version registries for comparability.
- Cost and sample efficiency are not benchmarked; report tokens-per-gain, optimizer evaluations-per-gain, and compare against classical baselines (e.g., BO) on efficiency fronts.
- Dataset and oracle versioning is not fully specified; provide immutable releases with checksums, semantic versioning, and change logs for questions, scenarios, oracles, and harness code.
- Cross-lingual performance is unassessed; build parallel scenario/question sets in other languages and measure transfer, bias, and accessibility.
These gaps define a concrete roadmap for expanding SDE’s scope, improving methodological rigor, and isolating which training, data, and tool-use interventions most effectively advance LLMs for real scientific discovery.

Feasibility hinges on access to domain tools and oracles, robust governance (especially for biology), reproducible open-weight baselines, and sustained community investment in scenario curation and standardization.
