The Department of Defense (DOD) is seeking proposals for the topic "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 capable of defending against universal AI threat vectors. The Army is prioritizing 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 use the xTechScalable AI prize competition to identify small businesses that meet the criteria for award, and only winners of the competition will be eligible to submit a proposal under this topic. The project will have three phases: Phase I involves submitting a Direct to Phase II (DP2) proposal, Phase II involves producing prototype solutions for evaluation by soldiers, and Phase III involves completing the maturation of the technology and producing prototypes for further development and commercialization. The deadline for proposal submission is March 31, 2025. For more information and to submit a proposal, visit the solicitation agency's website at [solicitation_agency_url].
