LACS Asset Classification Standard
LACS is a simple way of classifying how much AI was involved in the creation of 3D models, textures, sound effects and other assets that may be included in larger creative works such as video games. LACS does not apply to the creative works themselves, only to the assets.
How does LACS work?
Asset creators self-declare their work as one of three categories:
- LACS-H (Human-Made): Indicates the asset was created entirely by human effort, potentially with the use of software tools, but without any generative or assistive AI involvement beyond what is defined as an Inconsequential Algorithmic Element (IAE) in the specification (section 4, third point). Basically, you can’t use AI unless the AI does something very, very trivial.
- LACS-A (AI-Assisted): Indicates the asset was created through a collaborative process involving both human and AI, where both have made significant contributions to the final product. The human provides creative direction and makes key artistic choices, while the AI assists in generating variations, refining details, or performing other tasks that go beyond the scope of an IAE as defined in OSST.
- LACS-G (AI-Generated): Indicates the asset was created primarily or entirely by AI, with minimal human input beyond initial prompting, parameter setting, or curation of AI-generated output.
Why use LACS?
By labelling your assets with a LACS tag, regardless of which category, you demonstrate transparency and build trust with your customers. Your customers will have a better understanding of what they are buying, which is important if they themselves need to categorize their work’s overall use of AI.
How to use LACS
Simply determine the most appropriate class for the asset in question, and then label it as such!
If the marketplace in which you sell your assets does not support LACS labels, just include the tag, i.e. “LACS-A” in your asset description or as a regular search tag. Check out Appendix A of the LACS specification for more ideas on where to put your LACS tag.
