· Lean TheoremLang2MLIP: End-to-End Language-to-Machine Learning Interatomic Potential Development with Autonomous Agentic Workflows

The pith
A multi-agent LLM framework automates end-to-end development of machine learning interatomic potentials from natural language input.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Lang2MLIP is a multi-agent framework that accepts natural-language descriptions and solves MLIP development as a sequential decision-making task solved by large language models, with each decision-making agent observing the dataset, model, evaluation results, and execution log to choose corrective actions and revisit subsystems when failures occur.
What carries the argument
Multi-agent LLM decision system that observes dataset-model-evaluation states and selects actions without a predefined pipeline.
If this is right
- MLIP workflows no longer require a fixed sequence of stages chosen in advance.
- Agents can return to earlier subsystems when new failures are detected in multi-component systems.
- The method is demonstrated on a solid electrolyte interphase containing multiple interfaces.
- Non-experts can supply natural-language goals instead of designing active-learning loops.
Where Pith is reading between the lines
- The same state-observation and action-selection pattern could be applied to related tasks such as tuning density-functional parameters or force-field parameterization.
- Reliability will depend on how well the LLM interprets quantitative evaluation outputs in materials systems beyond the tested SEI example.
- Adding direct links to experimental feedback could further close the loop between simulation and measurement.
Load-bearing premise
LLM agents can reliably read dataset, model, and evaluation states and choose useful corrective actions without expert oversight or fixed stage rules, even for heterogeneous materials.
What would settle it
A run on the SEI system in which the agent repeatedly selects ineffective actions, leaving model error metrics unchanged or worse after several observation-action cycles.

read the original abstract
Developing machine learning interatomic potentials (MLIPs) for complex materials systems remains challenging because it requires expertise in atomistic simulations, machine learning, and workflow design, as well as iterative active learning procedures. Existing automated pipelines typically assume a fixed sequence of stages or depend on domain experts, which limits their adaptability to heterogeneous materials systems where the optimal curriculum is not known in advance. To lower the barrier to developing MLIPs for non-experts, we propose Lang2MLIP, a multi-agent framework that takes natural-language input and formulates end-to-end MLIP development as a sequential decision-making problem solved by large language models (LLMs). At each step, a decision-making agent observes the current dataset, model, evaluation results, and execution log, and then automatically selects an appropriate action to improve the model. This removes the need for a predefined pipeline and enables the agent to self-correct by revisiting earlier subsystems when new failures arise. We evaluate this approach on a solid electrolyte interphase (SEI) system with multiple components and interfaces. These results suggest that LLM-based multi-agent systems are a promising direction for automating MLIP development and making it more accessible to non-experts.

Referee Report
Summary. The manuscript proposes Lang2MLIP, a multi-agent LLM framework that formulates MLIP development as an end-to-end sequential decision-making task. Given natural-language input, a decision-making agent observes the current dataset, model state, evaluation results, and execution log at each step and autonomously selects actions to improve the potential, enabling self-correction by revisiting subsystems without a fixed pipeline. The approach is evaluated on a solid-electrolyte interphase (SEI) system containing multiple components and interfaces; the authors conclude that LLM-based agentic systems are a promising route to making MLIP development accessible to non-experts.
Significance. If the central claim holds, the work would meaningfully lower the expertise barrier for generating MLIPs on heterogeneous materials systems where optimal curricula are unknown a priori. The removal of rigid stage sequences and the explicit self-correction loop address a recognized limitation of existing automated pipelines. The manuscript does not yet supply the quantitative evidence needed to substantiate these advantages.
major comments (2)
- [Evaluation] Evaluation section: The manuscript reports results on a single SEI system but supplies no quantitative metrics (energy/force RMSE, active-learning iteration counts, agent failure rates, or success/failure logs), no baseline comparisons (expert-designed workflows or scripted pipelines), and no error analysis. Because the central claim is that the agents reliably observe states and choose corrective actions without predefined pipelines, the absence of these data leaves the reliability of autonomous correction untested.
- [Method] Method section: The observation representation (how dataset, model, and log states are encoded for the LLM), the action space, and the prompting strategy used for decision-making are not specified. These elements are load-bearing for the claim that the framework operates without domain-expert oversight or fixed pipelines.
minor comments (1)
- [Abstract] Abstract: The sentence 'These results suggest...' does not indicate what concrete outcomes were observed on the SEI system; adding one or two quantitative highlights would strengthen the summary.
Simulated Author's Rebuttal
Thank you for the constructive feedback on our manuscript. We agree that the evaluation and method sections require strengthening to better support the claims regarding autonomous agentic workflows for MLIP development. We address each major comment below and will incorporate revisions in the next version of the manuscript.

Referee: [Evaluation] Evaluation section: The manuscript reports results on a single SEI system but supplies no quantitative metrics (energy/force RMSE, active-learning iteration counts, agent failure rates, or success/failure logs), no baseline comparisons (expert-designed workflows or scripted pipelines), and no error analysis. Because the central claim is that the agents reliably observe states and choose corrective actions without predefined pipelines, the absence of these data leaves the reliability of autonomous correction untested.
Authors: We agree that the current evaluation is insufficient to substantiate the central claim. The manuscript does not include the requested quantitative metrics, baselines, or error analysis. In the revised version, we will add energy and force RMSE values, active-learning iteration counts, agent failure rates with success/failure logs, comparisons against expert-designed workflows and scripted pipelines, and a detailed error analysis of agent decisions. These additions will directly test the reliability of the autonomous self-correction mechanism. revision: yes

Referee: [Method] Method section: The observation representation (how dataset, model, and log states are encoded for the LLM), the action space, and the prompting strategy used for decision-making are not specified. These elements are load-bearing for the claim that the framework operates without domain-expert oversight or fixed pipelines.
Authors: We acknowledge that the Method section provides only a high-level overview and omits the load-bearing technical specifications. In the revision, we will expand this section to detail the observation representation (text encoding of dataset statistics, model state, evaluation results, and execution logs), the full discrete action space available to the decision-making agent, and the exact prompting strategies (including templates and few-shot examples) used to enable state observation and action selection without predefined pipelines or domain-expert intervention. revision: yes
Circularity Check
No circularity: framework proposal with no derivations or fitted parameters
full rationale
The paper presents Lang2MLIP as a multi-agent LLM framework for end-to-end MLIP development. No equations, parameters, predictions, or derivation steps appear in the abstract or description. The central claim is a methodological proposal for autonomous decision-making by agents observing states, without any reduction to prior fitted values, self-citations, or ansatzes. Evaluation is described at a high level on one SEI system but contains no quantitative self-referential claims that could be circular. This is a standard non-circular framework description with independent content.
