The Department of Defense (DOD) is seeking proposals for the topic of "xTechScalable AI" as part of the SBIR program. The Army branch is specifically interested in novel and disruptive concepts and technology solutions that can address the vulnerabilities of current machine learning pipelines and models. The goal is to develop comprehensive security models that can defend against universal AI threat vectors and are scalable to rapidly evolving threats. The Army is particularly interested in proposals that focus on systematic testing and evaluation methods, trusted and secure validation and verification strategies, continuous monitoring capabilities, improved transparency and assurance of code and data, and improved telemetry capabilities. The Army will prioritize submissions from winners of the xTechScalable AI prize competition. The project will involve a Direct to Phase II submission, followed by the production of prototype solutions that are easy to operate by soldiers. Phase III will focus on maturing the technology to TRL 6/7 and producing prototypes for further development and commercialization. The deadline for proposal submission is March 31, 2025.
