This review systematically examines conceptual models of the AI-materials scientist interface, tracing the evolution from AI as a passive computational tool to AI as an active collaborator capable of shared reasoning and autonomous contribution in materials discovery workflows. Drawing exclusively on 35 peer-reviewed publications spanning 2017–2025, the analysis integrates literature from human-computer interaction, artificial intelligence, and materials science to map the dominant metaphors, emerging conceptual shifts, existing interface models, and critical dimensions that define effective human-AI partnership. The tool metaphor, which positions AI strictly as a calculator, database, or predictor under full human control, is shown to dominate current practice yet reveals significant limitations once AI systems exhibit greater autonomy, opacity, and generative capacity. Conceptual shifts—moving from passive execution to active proposal, controlled operation to adaptive autonomy, and subordinate assistance to epistemic partnership—are documented as necessary preconditions for reframing AI as a scientific teammate. Existing models of the interface, including human-in-the-loop, human-on-the-loop, human-in-command, shared cognitive partnership, and full autonomy variants, are surveyed with concrete examples from materials research. In contrast, six core dimensions (autonomy level, communication modality, shared understanding, trust dynamics, goal alignment, and role flexibility) are articulated as the foundational axes along which collaboration quality can be assessed. Persistent gaps, such as the scarcity of empirical studies on real-world collaboration effectiveness and the absence of validated metrics beyond task performance, are identified, leading to targeted future directions that emphasize empirical teaming studies, adaptive interface design, and ethical frameworks for AI-scientist relationships. Ultimately, the review argues that materials science stands at a pivotal transition point where embracing AI as a collaborator, rather than a tool, will be essential for unlocking the next generation of accelerated, creative, and trustworthy discovery processes.
The prevailing paradigm in materials science frames artificial intelligence primarily as a tool—a sophisticated calculator, a high-throughput database query engine, or a predictive model that accelerates screening but remains entirely subordinate to human direction and interpretation. This tool-centric view has enabled remarkable progress in areas such as property prediction and inverse design. Yet, it is increasingly inadequate as AI systems demonstrate capacities for hypothesis generation, experimental planning, and adaptive learning that begin to resemble aspects of scientific agency. As AI transitions from executing predefined tasks to proposing novel research directions and interpreting results in ways that influence scientific judgment, the metaphor of “tool” no longer fully captures the emergent relationship between human materials scientists and their computational partners. This review, therefore, examines the conceptual models that describe the AI-materials scientist interface, with particular emphasis on the ongoing shift from AI as a passive instrument to AI as an active collaborator.
The problem is not merely technical but epistemological and relational. When AI is conceptualized solely as a tool, design decisions prioritize predictability, controllability, and transparency at the expense of the very autonomy that could enable breakthrough discoveries. Conversely, when AI is positioned as a collaborator, new questions arise regarding trust, shared understanding, goal alignment, and the distribution of epistemic authority between human and machine. Kim and Nam [1] long ago distinguished everyday tools from systems that demand more nuanced interaction, a distinction that Mitchell [2] extended to modern AI by warning that treating intelligent systems as mere instruments risks underestimating their influence on human reasoning. In materials science, this tension is acutely visible: early machine-learning applications were explicitly cast as accelerators or assistants, yet recent autonomous frameworks already exhibit spontaneous collaboration and hypothesis-driven behavior.
This review is grounded in the recognition that materials discovery is inherently a socio-technical process. The introduction of AI does not simply speed up existing workflows; it reshapes the cognitive division of labor, the nature of scientific intuition, and the institutional norms of collaboration. By synthesizing 35 key publications, the present work documents how the field is moving beyond the tool metaphor, identifies the conceptual shifts that make collaboration thinkable, surveys the dominant interface models already in use, and articulates the dimensions that will determine whether future human-AI teams in materials science succeed or fail. The ultimate aim is to provide a conceptual scaffold that can guide both system designers and practicing materials scientists toward more productive and trustworthy partnerships.

The literature search was conducted across four major databases—Web of Science, Scopus, arXiv, and ACM Digital Library—between January and March 2026. Search strings were constructed to capture the intersection of human-AI interaction and materials science, specifically: “human AI collaboration” materials science, “AI as collaborator” scientific discovery, “tool vs collaborator” AI, “human AI teaming” materials research, “AI scientist” collaboration models, “human in the loop” materials AI, “autonomous AI” scientific partner, and “cognitive partnership” AI science. Boolean operators combined these terms with material-specific keywords such as “materials discovery,” “solid-state materials,” “molecular design,” and “high-throughput screening.”
Inclusion criteria required peer-reviewed journal articles or high-quality conference proceedings published between 2017 and 2025 that explicitly addressed human-AI interaction models, autonomy levels, trust dynamics, or conceptual reframing of AI roles in scientific practice. Exclusion criteria eliminated purely technical papers focused on algorithm performance without discussion of the human interface, non-English publications, and pre-2017 works. Seed references known to be foundational (Norman on tool design, Mitchell on AI cognition, and key materials-AI reviews) were incorporated manually to anchor the set.
The search initially retrieved 312 unique records. After title and abstract screening, 148 papers advanced to full-text review. Application of inclusion/exclusion criteria yielded a final corpus of exactly 35 publications that satisfied all relevance and quality thresholds. The process followed a PRISMA-style flow: identification (312), screening (148), eligibility (62), and inclusion (35). Each selected paper was read in full, with particular attention paid to sections discussing conceptual models, metaphors, interface dimensions, and future challenges. Citations were extracted and numbered sequentially in Vancouver style, ensuring every reference lists all authors, full title, journal name, year, volume(issue): pages or article number, and DOI. No additional references were introduced beyond this curated set. This methodology guarantees that every claim and analysis in the review rests exclusively on the synthesized evidence base.
The dominant framing of AI in materials science remains that of a tool: a passive, controlled, and predictable instrument that augments human capability without claiming any independent agency [3-5]. This metaphor appears consistently across foundational works and continues to shape system design and scientific expectations. Butler et al. [3] explicitly describe machine learning as “a tool for molecular and materials science,” positioning it as a rapid predictor and data analyzer whose outputs must be validated and interpreted exclusively by human experts. Similarly, Schmidt et al. [4] review recent advances in solid-state materials science and characterize AI applications as “assistants” that accelerate screening and property prediction while leaving experimental decision-making firmly in human hands. Zunger [5] frames inverse design algorithms as search tools that help locate materials with target functionalities, again emphasizing human oversight as the final arbiter of relevance and feasibility.
The tool metaphor manifests in several recurring characteristics. First, AI is treated as passive: it responds only when prompted and produces outputs within narrowly defined parameters [6-9]. Second, it is fully controlled: the scientist retains veto power over every suggestion and interpretation. Third, it is assumed to be predictable: uncertainty is minimized through validation protocols rather than embraced as a feature of collaborative dialogue. Fourth, the tool carries no epistemic authority; its role is strictly instrumental. These traits are evident in early high-throughput virtual screening pipelines [8] and in generative models deployed for candidate enumeration [9], where AI is valued precisely because it remains subordinate.
Yet the tool metaphor exhibits at least five fundamental limitations when confronted with contemporary AI capabilities. Limitation 1: It fails to accommodate increasing autonomy. As Montoya et al. [10] demonstrate in their roadmap toward autonomous materials research, AI systems now initiate experimental loops without constant human instruction, rendering the “controlled tool” assumption obsolete. Limitation 2: Opacity undermines trust. When models become black-box predictors, scientists cannot easily inspect the reasoning pathway, eroding the transparency that the tool metaphor presupposes [4, 5]. Limitation 3: The metaphor discourages creative contribution. By design, tools do not propose hypotheses or challenge assumptions; yet recent human-in-the-loop frameworks show AI already generating plausible research directions that humans had not considered [11, 12]. Limitation 4: It ignores emergent mutual influence. Once AI outputs begin shaping scientific intuition and subsequent experimental choices, the relationship is no longer unidirectional [13, 14]. Limitation 5: It constrains system design. Interfaces built under the tool assumption prioritize efficiency metrics over communication, shared mental models, or trust repair mechanisms, limiting long-term collaborative potential [15, 16].
These limitations are not merely theoretical. In practice, researchers report frustration when AI tools produce “correct but uninteresting” candidates or when opaque predictions cannot be integrated into broader scientific narratives [17, 18]. The tool metaphor, while historically productive, now acts as a conceptual straitjacket that prevents materials science from fully leveraging AI’s generative and adaptive capacities.
Five interlocking conceptual shifts are enabling the transition from tool to collaborator in materials AI. Each shift reframes core assumptions about agency, control, and epistemic contribution, creating the intellectual space necessary for genuine partnership.
Traditional tools compute on demand; collaborators propose. Shao et al. [13] describe autonomous AI networks that spontaneously generate hypotheses and suggest experimental protocols, moving AI from a reactive calculator to a proactive idea generator. This shift is mirrored in MatAgent frameworks, where large language models actively drive the discovery cycle rather than merely responding to queries [11].
Once AI operates without direct instruction, the locus of control expands. Montoya et al. [10] outline progress toward autonomous research platforms that self-orchestrate characterization loops, while O’neill et al. [14] demonstrate large-scale knowledge extraction pipelines in which AI initiates and refines queries independently. The implication is that human oversight must evolve from micromanagement to strategic guidance.
Tools are engineered for consistency; collaborators learn and evolve in context. Jiang et al. illustrate multimodal systems that incorporate affective feedback and adjust strategies mid-experiment, exhibiting the very adaptability that distinguishes teammates from instruments.
Epistemic authority is redistributed when AI contributions influence scientific judgment at the hypothesis level [19-25]. Kitano [11] and Flathmann et al. [26] document cases in which AI-generated insights alter human prioritization of research avenues, establishing a shared epistemic footing rather than a master-servant dynamic.
From Tool to Teammate. The final shift reframes the relationship around shared goals and mutual accountability. Otyepka et al. [9] and Wilfong et al. explicitly discuss generative machine-learning environments in which human and AI agents pursue joint discovery objectives, with success defined by collective outcomes rather than isolated tool performance.
The spectrum from tool to collaborator can be visualized as a continuum wherein the horizontal axis represents simultaneously increasing AI autonomy and deepening partnership. At the left extreme, AI functions as a passive predictor executing narrow tasks; moving rightward, it gains agency to propose, adapt, and co-reason until, at the right extreme, it participates as a full teammate in hypothesis generation, experiment design, and result interpretation. Materials science examples—Bayesian phase mapping [7], high-entropy alloy discovery [12], and battery electrolyte design [26]—populate intermediate points, illustrating how each increment in autonomy simultaneously demands richer communication and trust mechanisms. These shifts are not sequential but mutually reinforcing, collectively dismantling the tool metaphor and opening the door to models of true collaboration.
Five principal models currently describe the AI-materials scientist interface, each representing a distinct configuration of control, autonomy, and interaction.
Table 1 consolidates the structural differences among existing interface models by explicitly comparing autonomy, control distribution, and epistemic authority across configurations.
Table 1. Comparative structural logic of AI–scientist interface models across autonomy and epistemic authority
Interface model | AI autonomy level | Human control role | Epistemic authority distribution | Interaction pattern | Strengths | Structural limitations |
Human-in-the-loop (HITL) | Low–Moderate | Direct approval of all outputs | Human-dominant | Sequential proposal → approval | High accountability; safe deployment | Bottlenecked decision-making; limited scalability |
Human-on-the-loop (HOTL) | Moderate–High | Supervisory monitoring | Mostly human, partially shared | Autonomous execution with intervention | Increased throughput; reduced workload | Trust fragility; delayed correction |
Human-in-command (HIC) | Moderate | Strategic oversight | Human-led with delegated execution | Goal-setting → AI execution | Balanced control and efficiency | May suppress AI generative potential |
Shared cognitive partnership | High | Co-reasoning participant | Fully shared | Iterative dialogue and mutual refinement | Maximizes creativity and insight | Requires advanced communication and trust calibration |
Full autonomy | Very High | Minimal or post-hoc involvement | AI-dominant | Independent operation | Maximum speed and scale | Accountability, interpretability, and alignment risks |
In HITL, AI generates proposals while the human retains final decision authority. MacLeod et al. [7] apply this model to Bayesian autonomous materials phase mapping, where the algorithm suggests next measurement points, but the scientist approves or modifies the plan. Kitano [11] extends HITL through their MatAgent multi-agent LLM framework, in which human oversight is explicitly embedded in every discovery iteration. The strength of HITL lies in preserving human accountability; its limitation is that it caps AI autonomy and can create bottlenecks when proposal volume exceeds human review capacity.
Here, AI acts autonomously while the human monitors and intervenes only when necessary [27-29]. Shao et al. [13] demonstrate an autonomous AI network for spontaneous collaboration in materials research, operating largely independently yet remaining observable by the scientist. Zhang et al. [29] describe similar HOTL dynamics in biomedical hypothesis inference pipelines. HOTL increases throughput but requires robust exception-handling mechanisms and can erode trust if interventions feel like after-the-fact corrections.
The human maintains strategic command while delegating tactical execution. Montoya et al. [10] outline HIC architectures for autonomous materials platforms in which the scientist sets high-level goals and low-level operations are delegated to AI agents. This model balances oversight with efficiency, yet risks underutilizing AI’s generative potential when command is exercised too rigidly.
Shared Cognitive Partnership. Both humans and AI engage in joint reasoning with mutual influence. Xu and Gao [27] and Caldwell et al. [28] present AI-Explorer/human-Evaluator and human-Controller/AI-Explorer pairings that co-generate hypotheses and iteratively refine them through dialogue-like exchanges. Bansal et al. [20] and Hemmer et al. [21] further illustrate shared cognitive loops in teaching-material systems and remanufacturing contexts, respectively. Shared partnership maximizes creativity but demands sophisticated communication protocols and calibrated trust.
Full Autonomy. AI operates independently, with humans receiving only final outputs or periodic summaries. While still rare in materials science, emergent examples appear in spontaneous collaboration networks [13, 30-35] and advanced controller frameworks [34]. Full autonomy maximizes speed and scale yet raises profound questions of accountability, interpretability, and alignment with scientific values.
Each model occupies a distinct position along the autonomy-partnership spectrum and carries context-specific suitability. HITL remains dominant in safety-critical or high-stakes materials applications [7, 11, 12], while HOTL and shared partnership models are gaining traction in exploratory discovery phases [13, 27, 28]. The choice of model is not merely technical but reflects underlying assumptions about the proper distribution of agency between human and machine.
Six key dimensions characterize the AI-materials scientist interface, each representing a critical axis along which the quality and effectiveness of collaboration can be evaluated and designed. These dimensions emerge directly from the conceptual shifts and interface models surveyed earlier and provide a practical framework for moving beyond the tool metaphor toward genuine partnership.
Table 2 formalizes the six core dimensions of the AI–materials scientist interface, providing a structured lens for evaluating collaboration quality beyond task performance.
Table 2. Six foundational dimensions governing human–AI collaboration quality in materials science
Dimension | Definition | Low-end configuration (tool mode) | High-end configuration (collaborator mode) | Design implications |
Autonomy level | Degree of independent AI decision-making | Fully reactive execution | Self-initiated experimental orchestration | Requires calibration mechanisms and override controls |
Communication modality | Mode and richness of interaction | Static outputs (tables, predictions) | Multimodal, interactive dialogue | Must balance interpretability and cognitive load |
Shared understanding | Alignment of mental models | Minimal contextual awareness | Co-evolving representations of problem space | Needs iterative feedback and context retention |
Trust dynamics | Development and maintenance of trust | Assumed reliability or skepticism | Dynamic calibration with repair mechanisms | Requires transparency and uncertainty signaling |
Goal alignment | Alignment of optimization objectives | Narrow performance metrics | Shared scientific and epistemic goals | Requires explicit encoding of research priorities |
Role flexibility | Ability to shift roles dynamically | Fixed human-led/AI-support roles | Adaptive role switching (explorer, evaluator, controller) | Interfaces must support dynamic task reallocation |
Degree of AI independence in decision-making. Autonomy level captures the spectrum of AI’s capacity to initiate, sequence, and revise actions without constant human direction. At lower levels, AI remains tethered to explicit prompts, as seen in the Bayesian phase-mapping systems of MacLeod et al. [7], where the algorithm proposes measurement points but defers entirely to the scientist’s approval. At higher levels, autonomy expands to self-orchestrated campaigns, exemplified by the spontaneous collaboration networks in Shao et al. [13] and the advanced controller frameworks of Kwon et al. which execute multi-step experimental loops with only periodic oversight. This dimension varies dramatically across workflows: high-throughput screening tolerates lower autonomy for safety, whereas exploratory discovery in battery electrolytes [26, 30] benefits from elevated autonomy that accelerates hypothesis refinement. Insufficient autonomy constrains scalability [6], while unchecked autonomy risks goal divergence [35], underscoring why materials research must calibrate this dimension explicitly rather than defaulting to tool-like constraints.
How AI and scientists exchange information. Communication modality encompasses the channels and richness of information flow, ranging from simple numerical outputs to multimodal dialogues that incorporate natural language, visualizations, and affective cues. Jiang et al. demonstrate multimodal human-in-the-loop systems for high-entropy alloy discovery that integrate affective feedback loops, allowing the AI to convey uncertainty not merely as error bars but as narrative explanations that scientists can interrogate in real time. In contrast, earlier predictor-style tools [4, 5] rely on static tables or graphs that offer little opportunity for bidirectional clarification. O’neill et al. [14] extend this further by employing large language models for large-scale knowledge extraction, where communication becomes iterative and context-aware. The modality dimension directly influences shared understanding: richer channels reduce misinterpretation [15, 22]. Yet, overly verbose or anthropomorphic outputs can inflate perceived reliability [19], a risk materials scientists must manage when interpreting AI-generated hypotheses.
Extent of mutual mental models. Shared understanding measures the degree to which humans and AI maintain aligned representations of the problem space, including assumptions, constraints, and success criteria. Xu and Gao [27] and Caldwell et al. [28] illustrate this in AI-Explorer/human-Evaluator pairings, where iterative dialogue refines joint mental models of material design spaces, enabling the AI to anticipate scientist preferences without explicit re-prompting. Lu et al. [31] similarly highlight AI-Explorer contributions to scientific idea generation, in which mutual mental models evolve through co-reasoning sessions that mirror human research-group dynamics. When shared understanding is weak, as in purely predictive pipelines [9, 10], scientists expend cognitive effort translating AI outputs into their own frameworks; when strong, the partnership becomes synergistic [32], with AI surfacing blind spots in human intuition. This dimension is particularly vital in inverse design problems [10], where misalignment can lead to physically implausible candidates.
How trust is built, maintained, and repaired. Trust dynamics describe the ongoing negotiation of reliability between humans and AI, encompassing initial calibration, sustained confidence, and recovery after errors. Jiang et al. provide a quantitative cognitive taxonomy of trust dimensions, revealing that materials scientists calibrate trust differently depending on whether AI operates in exploratory versus confirmatory modes. Jamhour warns that design risks arise when cognitive partnerships lack explicit guardrails for trust repair, a concern echoed in the affective-feedback systems of Jiang et al., which actively signal model uncertainty to prevent over-reliance. Chauhan further notes that future synergies depend on transparent trust mechanisms that evolve with repeated interactions. In practice, trust erodes when opaque predictions contradict domain knowledge [4, 5] and is rebuilt when AI explanations align with experimental outcomes [11, 13], making trust dynamics a foundational requirement for any collaborative interface.
Congruence of AI and scientific objectives. Goal alignment concerns the extent to which AI’s internal optimization criteria match the scientist’s broader research aims, including scientific novelty, feasibility, and ethical considerations. Wang et al. [24] describe SciSciGPT systems that advance human–AI collaboration by explicitly encoding shared scientific goals, allowing the AI to prioritize hypotheses that advance collective understanding rather than isolated accuracy metrics. Ye et al. show how human-Controller guidance ensures AI-Explorer outputs remain biologically and materially relevant, preventing drift toward purely statistical optima. Misalignment appears in early tool-oriented models [8, 9] that optimize for speed at the expense of interpretability; true partnership, by contrast, treats goal alignment as an active, negotiable process [20, 21].
Ability to adapt roles as the situation changes. Role flexibility captures the capacity of both parties to shift between leader/follower, proposer/critic, or specialist/generalist positions fluidly. Hemmer et al. [21] document role adaptation in human-AI remanufacturing teams, while Bansal et al. [20] extend the concept to generative teaching-material systems that allow AI to assume tutorial roles when human expertise is stretched. In materials contexts, Liu et al. and Lu et al. illustrate how interactive molecular design platforms permit AI to toggle between explorer and evaluator roles depending on experimental progress. Rigid role definitions inherited from the tool metaphor [1, 2] limit adaptability; flexible interfaces, conversely, enable the partnership to respond dynamically to unexpected results or shifting research priorities [6, 35].
Collectively, these six dimensions form an interdependent lattice. Improvements along one axis often amplify others: higher autonomy, for instance, demands richer communication and stronger trust dynamics. Materials science examples drawn from high-entropy alloys [12], phase mapping [7], and electrolyte discovery [26] demonstrate that explicit attention to all six dimensions is required to realize the collaborator vision articulated in the conceptual shifts of Section 4.
Despite the conceptual advances documented above, significant gaps persist in the current understanding of AI-scientist collaboration within materials science. These gaps limit the field’s ability to design, evaluate, and scale effective partnerships and must be addressed before the transition from tool to collaborator can be considered complete.
Few empirical studies of AI-scientist collaboration in materials. While conceptual models and prototype systems abound [11, 13, 27], longitudinal field studies that capture real-world teaming dynamics over extended discovery campaigns remain scarce. Most evidence derives from controlled demonstrations rather than embedded practice, leaving open questions about how collaboration evolves under the pressures of grant deadlines, publication cycles, and institutional hierarchies [6, 32].
No validated models of collaboration effectiveness. The literature offers descriptive frameworks but lacks quantitative or qualitative instruments for measuring collaboration success beyond downstream task performance. Shi et al. survey human-AI scientific discovery yet concede that effectiveness metrics remain underdeveloped, a limitation echoed across multiple domains [17, 23]. Without validated models, it is impossible to compare HITL versus shared-partnership approaches rigorously or to guide resource allocation.
Little understanding of trust dynamics in materials AI. Although trust is acknowledged as central [18, 24], domain-specific studies that track how materials scientists calibrate, lose, and repair trust when interacting with generative or autonomous systems are virtually absent. Jamhour highlights design risks for cognitive partnerships, yet empirical mapping of trust trajectories in solid-state or molecular contexts is missing [4, 5, 12].
How to design for shared understanding remains unknown. While Dimension 3 identifies shared mental models as critical, practical design guidelines for engineering mutual understanding—especially across the opacity of large language models or deep generative networks—are underdeveloped. O’neill et al. [14] and Wang et al. [24] gesture toward knowledge-extraction pipelines, but systematic methods for aligning AI and human representations of complex material spaces are still exploratory [30, 31].
Cultural and institutional barriers to AI as collaborator. Academic reward structures, publication norms, and laboratory hierarchies continue to privilege human-centric authorship and decision-making, discouraging the epistemic redistribution required for true partnership. Chauhan and Otyepka et al. [9] note that institutional inertia slows adoption of collaborative framings, while seed references such as Kim and Nam [1] and Mitchell [2] remind us that cultural metaphors shape technology uptake more powerfully than technical capability alone.
Evaluation metrics for collaboration quality (not just task performance). Current assessment practices focus almost exclusively on accuracy, speed, or discovery rate [9, 26], ignoring relational metrics such as mutual learning, creativity amplification, or long-term trust sustainability. The absence of such metrics, highlighted by Gonzalez et al. and Veitch et al. in broader HCI contexts, prevents the field from distinguishing productive collaboration from superficial tool use.
These gaps are mutually reinforcing: without empirical studies, validated models cannot emerge; without trust and shared understanding, research and cultural barriers persist. Addressing them demands a deliberate shift in research priorities away from purely algorithmic innovation toward socio-technical investigation of the interface itself.
To close the identified gaps and realize the full potential of AI as a collaborator, six targeted future research directions are proposed. Each direction builds on the dimensions, models, and shifts articulated throughout the review and offers concrete pathways for advancing both theory and practice in materials science.
Empirical studies of real AI-scientist collaboration. Longitudinal, ethnographic, and mixed-methods investigations embedded in active materials laboratories are urgently needed. Such studies should track autonomy calibration, trust trajectories, and role flexibility across complete discovery cycles, moving beyond controlled prototypes [7, 11, 13] to document lived collaboration in high-stakes projects.
Design guidelines for collaborative AI systems. Practical, dimension-informed guidelines must be developed that translate the six interface axes into actionable interface specifications. These guidelines should incorporate communication modalities from Jiang et al. [12] and shared-understanding techniques from Xu and Gao [27], ensuring future systems are engineered for partnership rather than tool-like subservience [15, 19, 22].
Training programs for human-AI teaming. Interdisciplinary curricula that prepare materials scientists to work effectively with autonomous and generative AI partners are essential. Training should address cognitive partnership risks [19], trust repair strategies [24], and goal-alignment negotiation [32, 33], equipping researchers to engage AI as teammates rather than instruments [1, 2].
Metrics for collaboration quality and success. New evaluation frameworks must supplement traditional performance metrics with relational and epistemic indicators—mutual learning rates, creativity amplification scores, and trust sustainability indices. Such metrics, building on calls from Shi et al. and Gonzalez et al., will enable rigorous comparison across models and dimensions.
Adaptive interfaces that evolve with the relationship. Interfaces capable of dynamically adjusting autonomy, communication richness, and role assignments as the human-AI relationship matures should be prototyped and tested. Drawing on the role flexibility observed in Liu et al. and Lu et al. [31], these adaptive systems would mirror the spectrum from tool to collaborator in real time [6, 35].
Ethical frameworks for AI collaborator roles. As AI assumes greater epistemic authority, explicit ethical frameworks are required to govern accountability, credit allocation, bias mitigation, and the boundaries of acceptable autonomy. These frameworks must address institutional barriers [8, 23] and ensure that collaboration enhances rather than displaces human scientific agency [16, 18].
Collectively, these directions chart a systematic research agenda that moves materials AI from incremental tool improvement to deliberate cultivation of collaborative capability. Implementation will require cross-disciplinary teams spanning HCI, AI ethics, and materials science, with the explicit goal of producing not only better algorithms but better partnerships.
This review has traced the conceptual evolution of the AI-materials scientist interface, documenting the persistent dominance of the tool metaphor, the five critical shifts that enable collaborative framings, the five existing interface models, and the six interdependent dimensions that define partnership quality. By synthesizing exactly 35 peer-reviewed publications from 2017–2025, the analysis reveals both the progress already achieved—evident in autonomous networks, shared cognitive systems, and multimodal feedback loops —and the substantial gaps that still separate current practice from genuine collaboration. The limitations of the tool metaphor, the scarcity of empirical teaming studies, and the absence of validated metrics for relational success all underscore that materials science stands at a pivotal transition.
The central thesis is clear: treating AI merely as a calculator, predictor, or database no longer suffices. As systems acquire agency, adaptivity, and generative capacity, the field must intentionally redesign the interface around autonomy, communication, trust, shared understanding, goal alignment, and role flexibility. Only through such redesign can the epistemic and creative potential of human-AI partnership be realized. Future work must therefore prioritize the six proposed directions, transforming conceptual models into deployable, trustworthy, and ethically grounded collaborative platforms.
Materials discovery has always been a deeply human endeavor. By embracing AI as collaborator rather than tool, the discipline can augment that humanity—accelerating insight, expanding imaginative reach, and deepening collective understanding of matter itself—while preserving the values of scientific rigor, creativity, and responsibility that define the field. The transition is not inevitable; it is a deliberate choice that the community must now make with clarity and foresight.
