The Defense Advanced Research Projects Agency (DARPA) has issued an initial program solicitation titled "Kallisti," aimed at developing innovative strategies for national security decision-makers to effectively deter or incentivize actions by adversaries. The Kallisti program focuses on creating an algorithmic theory of mind to model adversaries’ situational awareness, assess their risk and reward structures, and predict future behavior in national security contexts. Proposals must be submitted by various dates leading up to a final written and oral proposal due date estimated for April 4, 2025. The program will run for 30 months, divided into three sprints, with multiple performers expected to be selected based on meeting specific goals. Proposers interested in more detailed information must request a Controlled Unclassified Information (CUI) addendum by February 14, 2025, and submit abstracts by February 28, 2025. The solicitation invites participation from businesses and research institutions capable of fulfilling these requirements. This solicitation reflects DARPA's continued commitment to advancing defense technologies and enhancing strategic decision-making capabilities.

The document outlines the responses to questions submitted during the DARPA STO Kallisti Industry Day, focusing on the Kallisti program, which aims to develop an advanced simulation environment for modeling human and adversarial behavior in national security contexts. DARPA will develop the Kallisti M&A and Adjudicator Environment with contributions from AFRL and other partners. The program will use simulated data only, as real-world data is not sufficient for testing. Key aspects include modeling disproportionate human behavior, including irrationality, and the integration of cultural factors within the simulations, which will use generalized cultural representations. The program encourages diverse methodologies from proposers, emphasizing novel approaches and resilience to various data scenarios. Funding will be based on standard milestone payments. DARPA seeks multi-institutional collaborations and encourages participation from non-traditional entities in the proposal process. The document outlines various technical requirements, evaluative metrics, and provides answers to operational and procedural inquiries for potential performers involved in Kallisti's development. Overall, the Kallisti program represents an innovative exploration into AI's capability to model complex behaviors relevant to national security.
