About this opportunity

AI summary

The Defense Advanced Research Projects Agency Information Processing Techniques Office seeks information on approaches, tools, and practices to reduce the time and cost of verifiable compliance checking by two to three orders of magnitude. DARPA envisions a capability that accepts natural-language requirements documents alongside concrete network configurations, reasons about requirement inconsistencies, redundancies, and incompleteness during an offline phase, and then verifies compliance in near real-time with human-understandable outputs. Respondents must submit all unclassified materials via email to [email protected] by November 13, 2026, at 5:00 PM Eastern Time. Submissions must be written in English and formatted as unprotected Microsoft Word, PowerPoint, or PDF files. Responses are not offers, cannot form a binding contract, and will not receive cost reimbursement.

Scope of work

  • Information on approaches to reduce compliance checking time and cost by 2-3 orders of magnitude
  • Capabilities for natural language understanding of complex requirements documents
  • Methods for abstract reasoning about network requirements for inconsistency, redundancy, and incompleteness
  • Capabilities to evaluate concrete network configurations against requirements in near real-time
  • Approaches for an intermediate formal system or domain-specific language bridging requirements and network configurations
  • Metrics for assessing translation fidelity, reasoning quality, and compliance evaluation accuracy
  • Identification of existing or needed datasets and shortcomings of current technologies

Documents to include with your response

  • Submitting organization name, Technical POC name, email, and phone number
  • One-page narrative addressing RFI questions
  • Up to two slides with visual depictions of key concepts, including a completed Table 1
