Questions and answers

What must happen to Marine Corps GenAI pilots?

All GenAI pilots shall be coordinated and registered with the Service Data Officer AI registry using an approved Marine Corps designated use case intake form, thereby ensuring compatibility with future Service level capabilities and to capture appropriate lessons learned and user feedback to shape enterprise solutions. (paragraph 4)

What are GenAI system users responsible for when entering information?

Responsible for their input to a GenAI system and have no expectations of privacy with respect to that input. (paragraph 4)

What must users do before using GenAI outputs?

Responsible for products and decisions made with the assistance of GenAI. System users should distrust and verify all outputs prior to use. (paragraph 4)

What must users label when GenAI outputs are used?

Responsible for labeling any document that was created, in whole or in part, with outputs from GenAI tools. (paragraph 4)

How often must GenAI systems undergo testing and evaluation?

Conduct test and evaluation in a controlled environment to ensure GenAI systems operate as expected. This test and evaluation will be conducted on a recuring basis to address engineering challenges introduced by the nondeterministic nature of GenAI. (paragraph 4)
