Key Terms

model-agnostic, large language models, zero-day vulnerabilities

3 terms

model-agnostic technical

"This next-generation, model-agnostic tool harnesses a diverse set of large language models"

An approach, tool, or test that works with any predictive or analytical model rather than depending on a single algorithm or vendor. For investors, model-agnostic methods let you compare, audit, and trust results across different forecasting systems—like using a universal charger that fits many phones—reducing reliance on one provider, making performance easier to validate, and lowering the risk that a single model’s quirks drive investment decisions.

large language models technical

"harnesses a diverse set of large language models to accelerate vulnerability detection"

Large language models are advanced AI systems trained on vast amounts of text to understand and generate human-like writing, like a very fast reader and writer that learns patterns in words and sentences. They matter to investors because they can change how companies operate—automating customer service, speeding analysis, cutting costs, creating new products—and they introduce risks around accuracy, security and regulation that can affect a firm’s revenue and reputation.

zero-day vulnerabilities technical

"can patch zero-day vulnerabilities in real time"

A zero-day vulnerability is a software or system flaw that attackers can exploit before the maker has issued a fix, like an unnoticed backdoor that the owner doesn’t yet know how to lock. Investors care because such hidden weaknesses can lead to data breaches, service outages, regulatory penalties and costly emergency fixes; those outcomes can damage revenue and reputation, causing sudden stock drops or increased liability for affected firms.

RESTON, Va., July 29, 2026 /PRNewswire/ -- Government and commercial organizations could soon thwart potential cybersecurity threats by deploying Parcata™, a proprietary platform Leidos (NYSE: LDOS) has developed to autonomously find and fix software vulnerabilities.

This next-generation, model-agnostic tool harnesses a diverse set of large language models to accelerate vulnerability detection in first and third-party software and can patch zero-day vulnerabilities in real time.

"The use of AI by cyber adversaries has changed the game. We must detect and remediate before a breach," said Jason O'Connor, president of Leidos Intelligence. "Developed by our Kudu Dynamics team, with technology validated through DARPA's AI Cyber Challenge, Parcata will help organizations stay ahead of evolving threats. This tool will make sense out of the chaos and ensure the mission isn't dependent on any single frontier model."

The platform has demonstrated its capabilities through recent internal technical exercises and is being executed against Leidos code before it is deployed to mission environments.

This work aligns with Leidos' NorthStar 2030 strategy and its focus on AI-enabled capabilities and effects at operational scale across dynamic warfighting environments.
