Author Guidelines for Use of AI and LLMs in Manuscript Preparation

Preamble

The rapid development of large language models (LLMs) and generative artificial intelligence (GenAI) systems has wide-ranging implications for scientific research, workflows, and dissemination of scholarly content. The number of available models has increased alongside their usability and utility. These technologies have the potential to support researchers and others interested in scholarly information, but they also introduce challenges related to the scientific accuracy and integrity of the information.

Authors are responsible for the accuracy and nature of the content that they submit to the AAS journals. Proper attribution and accuracy in presentation and referencing are critical for the results in a publication to be trustworthy, and this trust can be undermined by the use of an LLM or GenAI technology to generate information and insight.

For the purposes of these guidelines, it is important to differentiate what is meant by “LLM,” “AI,” and “Generative AI.” An LLM is a type of AI designed to understand and generate human-like text. They are trained on massive datasets, often billions of words, that can generate and work with human language. By analyzing all these data, the model learns patterns and structures of language, enabling it to predict and generate text that could plausibly have been written by a human. Specific examples of LLMs are tools like ChatGPT, Gemini, and Claude for tasks such as writing, summarizing, translating, and coding. In contrast, “AI” is the simulation of human intelligence by computer systems to perform tasks like reasoning, learning, problem-solving, and perception. In practice, the term is not well-defined in modern usage, but for the purposes of this document, it covers LLM and machine learning (as it relates to article authorship). “Generative AI” is the use of AI to generate content, including text or images. 

These guidelines are not intended to cover the general use of AI or LLMs in research or in other contexts, but only the use of LLMs in the preparation of a manuscript for submission to the AAS journals. Guidelines for the use of LLMs in refereeing a manuscript are available here. These general guidelines are meant to assist authors in manuscript preparation.

The development of LLMs and GenAI, alongside guidelines for responsible use of them, is a rapidly evolving field. We expect to update these guidelines as the landscape changes. We encourage authors to check back here frequently for the most recent version. 

These guidelines were initially posted on 9 September 2026. If you have questions or feedback, please contact us via this form.

Guidelines for Use of AI and LLMs in Manuscript Preparation

All authors submitting to AAS journals sign the following agreement: “The author(s) certifies that the manuscript being submitted… consists of original work by the author(s).” In the era of AI, “original work by the author(s)” becomes (more) difficult to define, given the new modes of co-coding, co-analyzing, co-writing, and co-editing that authors are adopting with AI tools. The guidelines below are intended to help authors ensure that the content of the manuscript is original even when LLMs are used to assist in preparation of the manuscript.

If LLMs are used in the preparation of a submitted manuscript, the authors must disclose this use. We have provided examples of disclosure statements below. In addition, at submission authors may want to identify for the editor and referee which sections have benefited from the use of LLMs. 

AI cannot be listed as an author on publications, as outlined in this editorial by the AAS Editor in Chief. This is primarily because an AI tool cannot take responsibility for the scientific content of an article, which is a core responsibility of an author.

The International Association of Scientific, Technical & Medical Publishers generated recommendations for classification of AI use in academic manuscript draft preparation. These recommendations provided nine specific use cases for how LLMs/GenAI could be used in manuscript preparation, and these specific cases were used to guide the recommendations and case examples presented below.

Unacceptable Uses of LLMs in Manuscript Preparation

Uses of generative AI tools in manuscript preparation that are not in line with the professional and ethical standards for the AAS journals are never allowed. These unacceptable uses fall into three main categories:

1. Presentation of any kind of content generated by AI as though it were original research data or results from non-AI sources.

We anticipate that authors will incorporate AI tools in their workflows, and the expectation is that authors are transparent about the tools they have used in their research, as is the current norm in the field for reproducibility.

2. Undisclosed use of generative AI tools in manuscript preparation, including in accessing, generating, and editing figures, data, text, and references.

Authors have the final responsibility and accountability for the veracity of the figures, data, text, and references in their manuscripts; this remains true in cases where AI tools have been used in their access or generation. Authors are required to closely verify data, images, and references generated by AI tools for accuracy.

3. Plagiarism that results from the use of generative AI tools to access or generate figures, data, manuscript text, and references.

Plagiarism is defined in the professional and ethical standards for the AAS journals as “the act of reproducing text or other materials from other articles without properly crediting the source.” Authors should clearly understand the risks of incorporating figures, data, text, and references accessed or generated by AI tools in their manuscripts. However unintentional or incidental, plagiarism occurring in this manner will be treated as a serious ethical breach, as well as a legal breach of copyright if the reproduced material has been previously published.

If any of the above instances are identified in submitted manuscripts, they will be considered fraudulent misrepresentation of original work by the author(s), with commensurate consequences, up to and including retraction of the manuscript and banning of the author(s) from further publication in AAS journals.

Acceptable Uses of LLMs Requiring Disclosure

LLMs may not be used to generate any portion of a manuscript unsupervised. However, when supervised, they may be used to assist in aspects of the manuscript preparation process. Any use of LLMs in this process must be disclosed by the author.

Examples of acceptable uses of LLMs in the preparation process include:

  • Increasing accessibility.
    The use of LLMs to provide tools for increasing accessibility for authors is allowed. For example, LLMs may assist authors with learning differences such as dyslexia. The use of the LLM to increase text readability or structure should be disclosed. The reason for the use, however, does not need to be disclosed.
  • Refining, correcting, editing, or formatting the manuscript to improve clarity of language.
    LLMs may be used in the editing phase of manuscript preparation to ensure readability.
  • Refining or formatting data reported in the manuscript.
    LLMs and AI tools may be used in the readying of datasets for inclusion within the manuscript, and/or any supplemental data files published with the manuscript, specifically for enhancing the usability and accessibility of these data and datasets to a broad range of users.
  • Refining or formatting code reported in the submitted manuscript.
    LLMs and AI tools may be used in the readying of scripts or codes to be included in a manuscript, and/or supplemental files to be published with the manuscript, specifically for enhancing the usability and accessibility of these scripts or codes for a broad range of users. As a reminder, these guidelines concern the manuscript, not the data analysis. Therefore, this paragraph makes no recommendation on the use of AI in data analysis or writing code.

LLM Uses Requiring Extra Caution and Disclosure

The following uses of LLMs during manuscript preparation require extra caution and disclosure.

1. Drafting manuscript content.

Because LLMs are susceptible to hallucination and unreliable for attribution of ideas and phrases, their use in the generation of text carries significant risks of plagiarism and scientific misrepresentation. It is the authors’ responsibility to ensure that all text included in their manuscript is original and scientifically sound.

Examples of acceptable use of AI in drafting manuscript text:

  • An author writes an outline of the scientific argument they intend to make and uses ChatGPT to generate text connecting these arguments together in complete sentences. The author (and coauthors, as applicable) read the generated text and implement any necessary edits to ensure it is scientifically correct and that it conveys the authors’ intended meaning. This use is described in the authors’ AI disclosure statement included at the end of the article.
  • An author wishes to include a summary of a specific published article in their manuscript. They prompt ChatGPT to summarize the article in the desired number of words. They then check that the summary is factually correct and that it faithfully conveys the findings of the article. The author and coauthors implement any necessary edits to ensure it conveys the intended meaning. This use is described in the authors’ AI disclosure statement.

Example of unacceptable use of AI in drafting manuscript text:

  • An author prompts ChatGPT to write the introduction section of an article on a particular topic. The author copies and pastes the generated text without reading it. This use is unacceptable whether or not the author discloses their LLM use.

2. Using AI to translate manuscript text written in a language other than English for the purposes of publishing.

Example of acceptable use of AI-assisted translation:

  • An author writes a paragraph in Spanish and uses ChatGPT to translate it to English. That author or a co-author reads the translated paragraph and edits it, as appropriate, to ensure that it conveys the authors’ intended meaning. At the end of the article, the authors disclose their use of ChatGPT for translation.

Example of unacceptable use of AI-assisted translation:

  • An author writes a paragraph in German and uses ChatGPT to translate it to English. The author copies and pastes the translation into the manuscript without reading it or asking anyone else to read it.

3. Generating, refining, correcting, editing, or formatting images, diagrams, or other figures for illustrative purposes only.

It is not possible to trace source material when images are generated by LLMs. Authors are responsible for doing due diligence to ensure images are not copies of others’ work. The use of tools to create illustrations must be disclosed and should include the specific tool used, and even potentially the prompt, in the image caption.

Examples of acceptable use:

  • Creating cartoons or diagrams for illustrative or explanatory purposes to explain complex phenomena or methods.
  • Creating illustrative images of physical systems to provide context or background to scientific results.

Examples of unacceptable use:

  • Generating scientific plots from unknown data provided by the LLM.
  • Presenting generated images as research outputs in themselves or as representing research outputs.

4. Generating, refining, correcting, editing, or formatting visualizations of research data or results.

GenAI tools and LLMs may be used to generate visualizations of research data or results, but care should be taken to ensure the accuracy of the result and that the visualization faithfully represents the data. Authors are responsible for ensuring the accuracy and integrity of what is submitted and published.

Examples of acceptable use:

  • Using AI tools to generate graphs, tables, or other visualizations of research datasets generated and provided by the author(s). The authors double-check the output to ensure faithfulness to the data, for example by checking the axis limits and checking that no data have been artificially added/removed by the tool. The figure caption should include the specific tool used, and, if possible, the prompt.
  • An author creates a plot from a dataset and uses AI tools to make it more accessible (adjusting axes, font sizes, colors, etc.).

Examples of unacceptable use:

  • Using AI tools to generate scientific visualizations with no oversight. For example, using an LLM to generate a visualization of the authors’ data, without double checking for accuracy such that the presented results represent a skewed version of the data.
  • Using AI tools to generate scientific visualizations without providing source data. For example, the authors ask the tool to create a graph of two data products but do not provide the data.
  • Using AI tools to manipulate data values to change the results.

5. Assisting with gathering references.

LLMs have proven to be powerful tools for identifying previously published articles in a given research area, and they are being used by many researchers during the information-gathering phases of their projects. At the same time, numerous experiments have shown that the publication lists generated in this way are often incomplete, and in the worst cases can even include entirely fictitious articles (hallucinated publications). The lists can also be more heavily weighted toward frequently appearing or cited articles, which can introduce a degree of groupthink into the compilations, causing important work by less visible researchers to be overlooked.

With these factors in mind, LLMs can provide a useful tool for supplementing references gathered using more traditional tools, but authors should refrain from relying solely on LLMs for generating the list of articles cited in their manuscripts. Authors should also apply commonsense checks to the LLM-generated references to ensure the legitimacy of the articles and their relevance to the research being cited, for example, by downloading the article to confirm its relevance (good practice regardless of where the reference came from), and even to confirm that the cited article actually exists. Publishing fictitious references is regarded as a serious professional breach, and it can result in the article being retracted by the publisher, with longer-term consequences for the authors. Authors should also bear in mind that they are responsible for citing and crediting previous work that relates directly to their own research, regardless of whether said articles were recovered by an LLM search. The application of an LLM does not reduce the need to also employ more traditional tools, such as the Astrophysics Data System (ADS), to ensure a complete and unbiased check of the literature.

Disclosure Statements

At submission, authors are required to disclose whether or not AI/LLMs were used in manuscript preparation. This disclosure statement is required for intellectual honesty and integrity. The statement should include the particular tool used as well as what it was used for. A potential tool to assist in declaration statements can be found here.

Some potential disclosure statement examples include:

  • Machine learning tools were used to suggest language improvements within the manuscript.
  • AI tools were used to assist with refinement of the presentation of code used in the research process and reported in the manuscript. The GAI tool used was ChatGPT.
  • AI tools were used to generate part of the manuscript text. The GAI tool used was Gemini 3.5 Flash. Responsibility for the final manuscript text lies entirely with the authors.
  • AI tools were used to assist translation of an author’s original work into a secondary language for inclusion in the manuscript. The GAI tool used was Claude Sonnet 4.6.
  • AI tools were used to visualize or refine visualizations of research data/results in the manuscript. The authors declare the use of generative AI in the research and writing process. According to the GAIDeT taxonomy (2025), the following tasks were delegated to GAI tools under full human supervision:
    • Code optimization
    • Visualization
    • Proofreading and editing
    The GAI tool used was Claude Sonnet 4.6.
    Responsibility for the final manuscript lies entirely with the authors.
    GAI tools are not listed as authors and do not bear responsibility for the final outcomes.
