Nov 27 2025 IPTC Photo Metadata Standard adds new properties for AI-generated content

An image generated by Bing Image Creator using the prompt “A cute robot sitting at a French-style cast iron table in a sunny garden, drawing a picture in a notebook”. This image contains the new IPTC Photo Metadata fields “AI Prompt Information”, “AI System Used” and “AI Prompt Writer Name”. Note that adding the new IPTC Photo Metadata properties has rendered the C2PA metadata invalid.

The IPTC Photo Metadata Working Group has released version 2025.1 of the IPTC Photo Metadata Standard, including properties that can be used for AI-generated content.

The new properties are:

  • AI System Used
    Definition: The AI engine and/or the model name used to generate this image.
    User Note: For example, ChatGPT DALL-E, Google Gemini, ChatGPT
    Suggest help text: Enter the name of the AI system and/or the model name used to generate this image.

  • AI System Version Used
    Definition: The version of the AI system used to generate this image, if known.
    Suggested help text: Enter the name or number of the version of the AI system used to generate this image.

  • AI Prompt Information
    Definition: The information that was given to the generative AI service as “prompt(s)” in order to generate this image.
    User Note: This may include negative [excludes] and positive [includes] statements in the prompt.
    Suggested help text: Enter the information given to the generative AI service as “prompt(s)” in order to generate this image.

  • AI Prompt Writer Name
    Definition: Name of the person who wrote the prompt used for generating this image.
    User Note: This person should not be considered as the image creator.
    Suggested help text: Enter the name of the person who wrote the prompt used for generating this image.

IPTC’s specification materials have been updated to accommodate the new properties:

The new properties are expected to be implemented in software tools soon. The popular open-source tool Exiftool already supports the new properties, since version 13.40 which was released on October 24th 2025.

Thanks to everyone who contributed to our request for comments on these new properties. We made several changes based on feedback from IPTC members and others, so your contributions were well appreciated.
