Introduction

Large Language Models (LLMs) have rapidly moved from novelty to valuable research tools across scientific disciplines. In the last few years, models like OpenAI’s GPT-4 and Anthropic’s Claude have demonstrated unprecedented abilities to generate and analyze text, inspiring scientists to integrate them into research workflows. A recent survey of 816 scientists found that 81% have already incorporated LLMs into some aspect of their research workflow. Researchers are using these AI systems for tasks ranging from literature review and hypothesis brainstorming to data analysis and even writing code. This report provides a structured overview of (1) the recent developments in using LLMs across fields like biology, chemistry, physics, climate science and beyond; (2) the thresholds of capability – current limitations that prevent LLMs from becoming fully autonomous scientists; and (3) a roadmap of next steps toward more advanced AI-driven science, including emerging techniques and changes in scientific practice.

Recent Developments: LLMs in Today’s Scientific Research

Widespread Adoption and Cross-Disciplinary Use: LLMs are already permeating the academic landscape. Over the past two years, scientists have embraced general models (like ChatGPT and Claude) and specialized tools (like Galactica, SciPhi, Elicit) to augment their research. In mid-2023, a global Nature survey reported that about one-third of postdoctoral researchers were using AI chatbots, most commonly for refining text (63% of respondents) and for coding or data analysis (56%). This aligns with other findings that LLMs are deeply integrating into research: for example, Elicit (an AI literature assistant) has been used by over 2 million researchers to speed up literature reviews, find otherwise-missed papers, and even automate parts of systematic reviews​. Such tools help scientists rapidly sift through vast literature and draft summaries or reports. Researchers in fields from medicine to sociology are leveraging chatbots to summarize articles, translate technical jargon, and generate readable synopses of new findings, dramatically reducing the time required for background research​.

Literature Review and Knowledge Discovery: One of the most immediate impacts of LLMs has been on scholarly literature review and knowledge synthesis. Advanced models can search for and summarize relevant research papers on a given topic​, helping scientists stay up-to-date. For instance, Galactica, introduced by Meta AI in late 2022, was a 120-billion-parameter LLM explicitly trained on scientific papers, aiming to serve as a knowledge base for researchers​. Although Galactica was withdrawn after just three days due to rampant hallucinations (e.g. inventing fake research papers and wiki articles on absurd topics)​, it demonstrated the potential of domain-specific LLMs. More robust successors now combine LLMs with database querying: SciPhi, for example, integrates retrieval-augmented generation to build knowledge graphs from unstructured data, allowing scientists to query complex relationships. ChatGPT and Claude themselves, with fine-tuning on scientific content, have been used as “research librarians” – answering questions about prior work and even providing references (with mixed accuracy)​. However, caution is required: a systematic probing of GPT-4 showed it still hallucinates references in about 5.4% of its outputs (GPT-3.5 did so 36% of the time)​, underscoring the need for verification. Despite this, LLM assistants like Elicit have proven their worth by quickly retrieving relevant papers and extracting key data, which can significantly accelerate the literature phase of research.

Hypothesis Generation and Ideation: Beyond fetching facts, LLMs are increasingly used for creative ideation in science. Researchers report using chatbots to brainstorm research questions, generate hypotheses, and even suggest experimental designs in early stages of projects. Because LLMs have ingested vast scientific corpora, they can output plausible conjectures or connections that a researcher might not immediately think of. For example, some social scientists have used ChatGPT to propose theoretical explanations or study designs, treating it as a virtual colleague for high-level idea generation. In one intriguing development, scientists have begun to treat LLMs as substitutes for human participants in certain scenarios​. An LLM can simulate human responses in a survey or experiment, allowing investigators to perform in silico pilot studies. This approach has been suggested as a way to gauge the effects of an experimental manipulation before investing resources in a live study​. In psychology and behavioral economics, for instance, researchers have tested whether an LLM can predict how humans might respond to a questionnaire or scenario. While far from perfect, these proxies can augment human data, essentially generating synthetic data points to test an idea cheaply​.

Data Analysis and Computational Support: Another arena where LLMs shine is assisting with data interpretation and coding. Traditionally, analyzing a complex dataset or running statistical tests required significant programming effort. Now, LLM-powered copilots can write and debug code, run calculations, and create visualizations based on natural language instructions​. OpenAI’s introduction of Code Interpreter (later known as Advanced Data Analysis) for ChatGPT in 2023 was a turning point. This tool allows a user to upload data files and ask questions in plain English; the LLM will then execute Python code to answer (with the code and result shown)​. For example, a researcher can ask to “calculate the correlation between these two variables and plot the trend,” and the LLM will handle the coding. This has made data exploration as easy as having a conversation, lowering the barrier for researchers less versed in programming. Early studies highlight that such capabilities let scientists focus on high-level interpretation while the AI handles the grunt work. Indeed, some describe this as akin to shifting from a manual to an automatic transmission in data science​. Similarly, Claude by Anthropic, which by mid-2023 featured a 100,000-token context window, allows users to feed entire datasets or lengthy documents (hundreds of pages) into a single query. This enabled tasks like digesting a full research paper or even a stack of papers at once – Claude can “summarize and explain dense documents like research papers” within one interactive session​. Such extended context means an LLM can synthesize information across a large corpus without needing separate searches, which is incredibly useful for comprehensive analyses.

Domain-Specific Breakthroughs: Across specific scientific domains, there have been notable pilot projects showcasing LLMs’ contributions:

• Biology & Medicine: LLMs are used to comb through biomedical literature and suggest new connections between genes, diseases, and drugs. Models like BioGPT (a GPT-derivative trained on biomedical text) and Google’s Med-PaLM have shown strong performance in answering medical questions and even passing medical licensing exams. In daily practice, biomedical researchers employ ChatGPT to summarize new papers, generate plain-language summaries of complex results, and even to help write sections of grant proposals or research articles (with human editing). There is experimental use of LLMs to propose potential drug targets or molecular hypotheses by synthesizing knowledge from genomics databases and publications. While domain experts must vet these suggestions, the AI often surfaces known relationships (a sanity check) and occasionally offers fresh ideas. Notably, GPT-4 was found to be on par with human scientists at writing certain sections of a biology paper (like introductions), in terms of coherence and content quality​. Such results hint that LLMs can take over some writing-intensive parts of research once provided with the relevant data.
• Chemistry & Materials Science: Researchers have tapped LLMs to help discover new materials and catalysts. A 2023 study from UC Berkeley showed that ChatGPT can be harnessed to text-mine chemistry literature and build structured datasets on demand​. In their project, the team trained ChatGPT to extract data on metal–organic frameworks (MOFs) – highly porous materials crucial for carbon capture and water purification – from hundreds of thousands of papers. The result was a comprehensive dataset of MOF properties that would have taken enormous manual effort to compile. With this, scientists can feed the AI-extracted data into predictive models, accelerating the design of new MOFs for climate mitigation​. “In a world where you have sparse data, now you can build large datasets,” said Omar Yaghi, the chemistry professor behind the project, noting that AI can now “mine it, tabulate it and build large datasets” from literature that no single person could systematically rea. Similarly, chemists use LLMs to plan organic syntheses by querying vast reaction databases: an LLM can suggest a sequence of reactions to create a target molecule, based on knowledge of published methods. These suggestions (sometimes provided by tools like IBM’s RXN or open models fine-tuned on chemical formulas) assist chemists in brainstorming synthetic routes. In materials design, integration of LLMs with robotic labs (discussed further below) is starting to enable closed-loop systems where the AI proposes a material, the robot synthesizes and tests it, and the results inform the next proposal.
• Physics & Mathematics: Physicists and mathematicians have been both excited and cautious about LLMs. On one hand, models like GPT-4 exhibit an ability to solve many textbook problems and even suggest proofs or code for simulations. For instance, GPT-4 can often derive or verify a formula by searching its internal knowledge (or writing a short program). A prominent mathematician, Terence Tao, noted in 2023 that current AI can generate “promising leads” for a working mathematician, especially when combined with tools like formal proof verifiers or computer algebra systems​. He anticipates that by 2026, AI (when tool-integrated) will be a trustworthy co-author for math research. Already, there are examples of GPT-4 assisting in discovering patterns or conjectures: for example, suggesting a possible relationship between mathematical objects which the human then formalizes. In physics, some researchers use LLMs to interpret results from simulations or experiments by asking for explanations of observed data trends. LLMs can also help write analysis scripts in Python/Matlab for processing physics data. However, pure text-based reasoning in complex physics is still unreliable – while an LLM might recite known physical laws correctly, it can just as confidently produce nonsense explanations if prompted outside its training distribution. Consequently, physicists use these models as brainstorming aides or for simpler tasks like unit conversions, basic derivations, or literature search, while critical derivations and experimental validations remain human-led.
• Climate & Earth Science: Climate scientists are exploring LLMs to aid in understanding and predicting complex environmental systems. One proposed use is feeding climate simulation outputs or observational data summaries into an LLM and asking for natural-language interpretations or plausible future scenarios. For example, ChatGPT has been discussed as a tool for climate model parameterization and scenario generation​. It could suggest how tweaking certain parameters (like carbon emission rates or ocean albedo) might affect outcomes, based on patterns it learned from climate reports. LLMs have also been used to generate multiple plausible narratives of future climate impacts (to help in risk assessment and communication). A 2023 commentary noted that ChatGPT could assist climate research by analyzing model outputs, generating hypotheses for climate dynamics, and even evaluating model performance. At the same time, specialized systems are being developed to ensure accurate and up-to-date climate information. ChatClimate, an LLM-based prototype introduced in 2024, grounds its answers in a curated climate science knowledge base to avoid the hallucinations and outdated info that a generic model might produce​. By providing sources (like IPCC reports) and citations with each answer, such systems aim to make AI a reliable assistant for climate policy makers and researchers. This trend of retrieval-augmented LLMs is likely to expand to other data-intensive fields, ensuring that the generative text is backed by current, verified scientific data.
• Interdisciplinary and Other Fields: In social sciences and humanities, LLMs like ChatGPT are used to accelerate qualitative analysis – for instance, helping to summarize interview transcripts or find themes in ethnographic notes. Early studies have tried using ChatGPT to perform thematic analysis on qualitative data, with some success in capturing obvious themes while missing subtle ones​. Economists use LLMs to quickly summarize policy documents or to draft sections of reports. In engineering and computer science, LLMs can serve as coding partners (for simulations or algorithm development) and as sounding boards for design ideas. Importantly, many scientists leverage LLMs for scientific writing assistance in general. Drafting papers, proposals, and presentations can be partially offloaded to these AI tools: researchers generate figures and results, then ask the LLM to compose initial drafts of method descriptions, related work summaries, or even entire introductions. A controlled study in 2024 found that GPT-4’s writing of a scientific review was comparable to human PhD students in terms of clarity and coherence (although humans needed to fact-check and polish the AI text)​. This indicates that LLMs are becoming true multipurpose aides in research – from inception of ideas to communication of results.

Thresholds of Capability: Current Limitations of LLMs as Scientific Agents

Despite their remarkable progress, today’s LLMs fall short of being fully autonomous scientists. Several critical limitations and capability thresholds prevent them from independently conducting reliable scientific research:

• Factual Accuracy and Hallucinations: LLMs have a well-documented tendency to “hallucinate” information – producing text that is convincing but false. In a scientific context, this is especially dangerous. Models like GPT-4 may occasionally invent nonexistent literature, misquote data, or assert false relationships. The case of Galactica illustrated this vividly: it began outputting fabricated papers and wiki articles (even citing fake authors and journals) when asked for information​. Open-ended queries can lead an LLM to confabulate just to satisfy the prompt. Evaluations show that even state-of-the-art models will sometimes generate bogus references or alter factual details if they don’t “know” the answer​. For example, when acting as a “research librarian,” GPT-4 produced fake citations ~5% of the time. This hallucination rate, while lower than earlier models, is non-negligible – especially because fabricated scientific content can be hard to immediately spot. Data fidelity is another aspect of this problem: if asked to summarize or analyze data, an LLM might subtly distort numeric values or experimental details, either through rounding errors or misinterpretation. Without ground-truth verification, these errors could propagate. In short, current LLMs lack an assurance of truthfulness, and they have no built-in mechanism to distinguish fact from a plausible-sounding lie. This limitation means that any LLM-generated scientific insight must be treated as a hypothesis – something to be checked – rather than accepted at face value. The scientific method demands verifiable truth, and LLMs are not yet reliable truth-tellers on their own.
• Reasoning and Analytical Limitations: Although LLMs can mimic some reasoning by virtue of pattern recognition, they struggle with complex logical or mathematical reasoning that is essential for scientific rigor. Researchers have observed that without special prompting or tools, even advanced models fail on tasks requiring multi-step deduction or precise calculation. For instance, GPT-4 cannot correctly multiply two four-digit numbers in its head with high reliability – a seemingly trivial task for a “smart” agent. It often makes arithmetic mistakes unless explicitly guided to write a program or use a calculator. This hints at a broader issue: LLMs do not possess genuine reasoning abilities in the human sense, but rather correlate patterns seen in training data. As one analysis put it, they risk being “stochastic parrots,” regurgitating training patterns without true understanding. In scientific research, robust reasoning is vital for hypothesis testing, experimental design, and result interpretation. Current LLMs might follow a line of thought that looks logical but contains hidden fallacies or leaps. They lack a reliable internal model of the world to check consistency. For example, an LLM might propose an experiment that is physically impossible or logically circular, because it cannot fully parse causality and constraints. Some experts have gone as far as to say that today’s best model (GPT-4) is “utterly incapable of reasoning” in a rigorous sense​, pointing out that it can solve problems in formats it has seen before, but fails at truly novel puzzles requiring abstract thought. While that stance is debatable, it’s clear that reasoning accuracy is a key threshold: until LLMs can perform stable multi-step logical inference (or reliably use external reasoning tools), they will need human scientists to handle the heavy lifting of rigorous analysis.
• Reproducibility and Consistency: A cornerstone of science is reproducibility – if an analysis or result is valid, an independent party (or the same researcher later) should be able to reproduce it. LLMs pose challenges here. Their outputs can be variable; they involve some randomness (temperature setting) and even with the same prompt, they might produce slightly different answers from run to run. This means an LLM might generate a useful insight once, but fail to do so consistently. Moreover, because the reasoning they perform is largely hidden in billions of neural weights, the lack of transparency makes it hard to trace why a conclusion was reached. If an AI assistant suggests a surprising hypothesis, a scientist cannot easily interrogate the model’s chain of thought or assumptions – unlike a human colleague who could explain step by step. This opaqueness complicates trust and reproducibility. In addition, LLM-generated code or analysis might have subtle bugs that are not immediately evident. A human programmer can write a detailed methods section; an AI’s internally generated script might not document its every decision. Reproducing that exact analysis could be difficult unless logs or code are saved. There’s also the issue of versioning: as models improve, a future GPT might not produce the same output given an identical prompt that a 2023 GPT-4 did. So citing an AI’s result in a paper is problematic because others might not replicate it if they can’t query the exact same model version with the same hidden state. Scientific reproducibility thus demands new strategies when involving LLMs – such as recording the AI’s prompts and outputs verbatim as part of the method, or using open-source models that can be preserved for verification. Until these practices mature, fully autonomous AI research is held back by the difficulty of ensuring that results are reliable and repeatable.
• Integration with Experimental and Physical World: Real scientific progress usually involves interacting with the physical world – running experiments, gathering empirical data, measuring phenomena. LLMs in their current form are disembodied text generators; they cannot directly perform experiments or handle physical apparatus. This limits their autonomy. An LLM might suggest an experiment (e.g., “synthesize a certain compound and test it for X property”) but it has no ability to carry it out without human or robotic intermediaries. Fully autonomous science would require coupling the AI’s “brain” with laboratory automation. While robotics and automated labs exist (so-called self-driving labs that can conduct high-throughput experiments), connecting an LLM to reliably operate such systems is non-trivial. There have been early forays – for example, the concept of a “Robot Scientist” has been around for over a decade (robots like Adam and Eve in the 2000s could autonomously run microbiology experiments)​. But those systems used more structured AI and hard-coded experiment selection logic, not the free-form reasoning of LLMs. Integrating LLMs could make lab robots more flexible (able to change plans on the fly through natural language instructions), yet safe and effective integration requires overcoming error and ambiguity in LLM outputs. An imprecise instruction from an AI could break expensive equipment or lead to invalid experiments. Currently, no LLM has direct real-time access to a wet lab or a telescope or a particle accelerator – and for good reason. Until an AI’s decisions can be fully trusted or constrained, giving it physical agency is risky. Therefore, LLMs remain advisors rather than actors in experimental science. This gap marks a significant threshold: achieving true autonomy will require LLMs to be paired with robotics and experimental controls in a way that is fail-safe and verifiable. Scientists will need to closely supervise any AI-directed experiment, which means we are still far from a “lab fully run by an AI” in practice.
• Accuracy, Bias, and Validation Constraints: Even aside from hallucinating facts, LLMs carry biases learned from their training data that can skew scientific judgment. They might over-represent viewpoints or conventional wisdom present in literature and under-represent minority or novel perspectives​. This could lead to less creative or less inclusive scientific ideas. There are also concerns about how to validate discoveries made by an AI. If an LLM proposes a new theory, confirming it still requires human-designed tests. The AI might not reliably judge its own idea’s validity – it has no intrinsic notion of truth, only what sounds plausible. Moreover, issues of credit and ethics arise: if an AI significantly contributes, how do we acknowledge it? The consensus so far is that LLMs cannot be authors on scientific papers​ because they cannot take responsibility for the content​. All these challenges imply that LLMs, in their current form, must be used with caution. They are powerful augments to human intellect, but not replacements for the careful, critical thinking and empirical validation that scientists practice. As Emily Bender and colleagues argue, LLMs today are often misused or overhyped, and their limitations mean that sometimes more specialized and transparent tools (like smaller domain models or symbolic algorithms) might be preferable for a given research task​. Reaching the next stage of AI-driven science will require surmounting these limitations or finding ways to mitigate them through new approaches.

Next Steps and Roadmap: Toward AI-Enhanced and Autonomous Science

The path forward for LLMs in science involves both technical innovations and shifts in scientific practice. Experts envision a future where AI is tightly woven into the fabric of research, but getting there will require overcoming the above limitations step by step. Here we outline key directions and a plausible roadmap for more advanced AI-powered scientific development:

• Combining LLMs with External Tools and Knowledge Sources: One immediate and promising step is to augment LLMs with retrieval systems, databases, and computational tools. This trend is already underway: providing an LLM access to an external knowledge base can greatly reduce hallucinations and keep information up-to-date. Rather than relying on a model’s frozen training data, systems like ChatClimate feed the model verified facts on demand so that it draws from a “live” memory of scientific knowledge​. This retrieval-augmented generation (RAG) approach supplies citations and grounded context for the model’s answers, improving factual accuracy. We can expect future scientific LLMs to be connected to literature databases (for the latest papers), scientific data repositories, and even real-time experimental data streams. Likewise, integrating computational tools addresses reasoning and math limitations. Already, ChatGPT with Code Interpreter can seamlessly hand off a calculation to Python when needed. In the future, an LLM agent might automatically invoke a symbolic algebra system for a tough equation, a statistical package for data analysis, or a theorem prover for checking a logical inference. By serving as the “glue” that knows when to call a specific tool, the LLM can compensate for its weaknesses. Terry Tao’s vision of a “2026-level AI” that is a trustworthy co-author was predicated on such integration – the AI would use formal proof verifiers, search engines, and math solvers alongside its language abilities​. In essence, the LLM becomes the orchestrator of a suite of specialized modules (neural and symbolic), combining their strengths. The roadmap’s first phase is thus creating hybrid systems where LLMs interface with tools for data, calculation, and knowledge retrieval. This could drastically improve reliability and allow AI to tackle tasks that are beyond a standalone LLM’s capability.
• Enhanced Reasoning via Structured and Symbolic Methods: To push beyond pattern imitation, researchers are exploring ways to inject more robust reasoning processes into AI. One avenue is neuro-symbolic systems, which blend neural network flexibility with symbolic logic’s rigor. For example, an LLM might generate hypotheses in natural language, but then those hypotheses are translated into a formal representation that a logic engine or knowledge graph can verify against known constraints​. Efforts like SciPhi’s knowledge graph construction or projects on LLM-driven symbolic regression of scientific equations​ exemplify this. Another approach is using multiple AI agents or a single AI in an iterative self-refinement loop to emulate scientific reasoning. An “AI researcher” could generate a possible solution, then an “AI reviewer” agent checks it for flaws or internal consistency, and they iterate – a bit like an internal peer review. This agent-based approach (sometimes called an AI ‘chain-of-thought’ or self-reflection) can catch reasoning errors that a single-pass LLM would miss. We already see simple versions of this when an LLM is prompted to “think step by step” or to critique and improve its previous answer. Future architectures may formalize this into distinct modules: one that proposes ideas, one that tests them (perhaps by simulating experiments or cross-checking against data), and one that refines conclusions. In mathematics and theoretical physics, coupling LLMs with formal proof systems will be crucial – the LLM might draft a proof in natural language and a proof assistant then tries to verify each step, with feedback guiding the LLM to fix gaps. By 2025–2030, we anticipate LLM-based systems that can reliably solve novel scientific problems by decomposing them into sub-tasks and rigorously validating each part (through either computation or logic), rather than relying on end-to-end guesswork. Achieving this will significantly close the gap between human-like reasoning and AI capabilities, inching us closer to autonomous research agents that reason as well as generate.
• Autonomous Experimentation and “AI Scientists”: A bold frontier – and perhaps the truest test of AI in science – is the development of systems that can conduct the entire scientific process. This includes not just thinking and writing, but planning and executing experiments or simulations, then interpreting the results and looping back. Recent developments suggest we are taking the first steps here. In 2024, a team introduced “The AI Scientist”, a prototype that automates the research lifecycle from idea generation and coding experiments to analyzing results and writing a paper​. In a demonstration on machine learning research problems, this system (built on LLMs and other AI components) was able to produce research papers that the authors claimed were of submission quality to top conferences​. While this was in a very meta domain (AI designing AI algorithms), it shows what’s conceptually possible. Similarly, in materials science, self-driving labs are being connected with AI planners. In a closed-loop setup, an AI can propose a material to synthesize, a robotic system performs the synthesis and tests it (e.g. measuring a new catalyst’s efficiency), and the results feed back into the AI to propose the next experiment​. Over multiple cycles, this can dramatically accelerate discovery – a process that might take human researchers months or years could play out in days. The vision for the future is an AI-driven laboratory where an LLM-like agent, augmented with experimental data and in control of lab automation, can carry out experiments 24/7, systematically searching a hypothesis space. Scientists would take on a supervisory role: setting high-level goals (“find a material that does X” or “test this theory’s predictions”) and the AI lab agent does the rest. Importantly, human oversight will remain essential to ensure safety and sense-check results, but their day-to-day involvement could be minimized. The figure below conceptualizes this integration of AI, automation, theory, and human insight in next-gen labs:

Next-generation intelligent research laboratories integrate multiple components: automated high-throughput experimentation, theoretical modeling, and AI-driven decision-making, all guided by human insight. Such systems aim to autonomously carry out cycles of experiment and analysis, allowing researchers to focus on creative direction and interpretation.

To reach this stage broadly across disciplines, significant work is needed in integrating LLM agents with domain-specific hardware and software. Each field will have its own challenges – an AI chemist’s robot needs fine motor skills and safety checks, an AI neuroscientist might need to interface with imaging devices, an AI ecologist might run large-scale simulations. The coming years will likely see incremental automation: perhaps AI managing parts of an experiment (like data collection and basic analysis) while humans handle complex procedures. Gradually, as confidence and capability grow, the AI could take on more. Achieving trustworthy autonomous experimentation will also require progress in the previous roadmap items (better reasoning and tool-use), because conducting experiments involves making many decisions (how to handle anomalies, whether data is sufficient, etc.) that demand sound judgment.

• Human-AI Collaboration and New Scientific Practices: Rather than envision AI replacing scientists, most experts foresee a collaborative future, where human creativity and AI efficiency combine. This will entail shifts in scientific practice and culture. Researchers will need to become skilled at “prompt engineering” – knowing how to ask the AI the right questions and how to steer it away from pitfalls. The role of a scientist may become more of a coach or supervisor for AI: for example, setting up an AI-driven analysis, monitoring its progress, and intervening if something seems off. There is also a push for developing guidelines and ethical frameworks for AI use in research. Issues like authorship credit, data privacy, and result verification will need standardized protocols. Already, major journals and conferences have policies requiring disclosure of AI tool usage and barring AI from being listed as an author. These will evolve as AI contributions become more substantive. Another likely change is an increased emphasis on transparent reporting when AI is involved: scientists might publish not just their results, but also the AI prompts and outputs that led to those results, as part of the supplementary material, to ensure clarity and reproducibility. Additionally, as AI handles more routine work, scientists could spend more time on the creative and conceptual aspects of research – formulating big questions, dreaming up new experiments, and interpreting the significance of findings. In education, we may train new scientists in how to effectively work with AI teammates.

Finally, keeping humans “in the loop” is not just a safeguard but a necessity for guiding the direction of science. As one perspective noted, humans should retain responsibility for setting the research agenda and ensuring ethical conduct, even in an AI-driven future​. An AI might be extremely efficient at achieving a goal, but society and scientists must decide which goals matter and why. Therefore, the roadmap to autonomous science isn’t about AI alone; it’s about co-evolution of AI systems and scientific workflows. In the coming decade, we will likely witness “AI-steered” discoveries – for example, an AI might propose a new drug molecule that ends up saving lives – but those successes will almost certainly be in partnership with human experts who validate and channel the AI’s contributions appropriately.

Conclusion

Large Language Models have quickly become versatile assistants in laboratories, field sites, and offices of researchers worldwide. They are already extending our abilities – reading more papers than any person could, suggesting ideas unbounded by human biases, and handling menial tasks from coding to proofreading. The current state of LLMs in science is that of a powerful augmentation tool: transformative when used wisely, but prone to severe errors if used naively. We have outlined how scientists across disciplines are harnessing LLMs and also where the technology falls short. Overcoming issues of accuracy, reasoning, and integration is crucial before we grant AI more autonomy in discovery. The future outlook is optimistic: through hybrid systems, better reasoning algorithms, and careful integration, LLMs are poised to evolve from intelligent assistants to genuine research collaborators – and eventually, to autonomous investigators tackling problems at scales and speeds humans never could. If we navigate this path responsibly, the coming era could see an explosion of scientific progress, with “AI scientists” working alongside human scientists to push the frontiers of knowledge. The journey has begun, and the next few years will be pivotal in determining how far and how fast LLM-driven scientific research can advance.
