Overview

Gray Swan AI: Frontier AI Red-Teaming & Safety Platform

Gray Swan AI is Frontier AI safety company building Cygnal (red-teaming) and Shade (jailbreak defenses). AI safety has become a procurement requirement in many enterprises and a regulatory requirement in jurisdictions including the EU. Gray Swan's bet is that academic-grade red-teaming — by the researchers who literally wrote the jailbreak papers — is uniquely defensible. The OpenAI and Anthropic partnerships validate that thesis at the frontier-lab level.

Key Features

  • Frontier AI safety company building Cygnal (red-teaming) and Shade (jailbreak defenses)
  • Founded in 2024 by Zico Kolter and Matt Fredrikson (Carnegie Mellon CS faculty) plus Andy Zou
  • Researchers behind some of the most-cited adversarial-ML and jailbreak papers
  • Approximately $5.5M+ seed; backed by Pillar VC and others
  • Partners with OpenAI, Anthropic, and other frontier labs on red-teaming
  • Runs public jailbreak competitions that expose frontier model weaknesses
  • Used by AI deployers and regulators to evaluate safety before production rollout

Ideal Use Case

Frontier AI labs and enterprise AI deployers that need rigorous red-teaming before production — and AI regulators evaluating safety claims from model vendors. Particularly strong fit for high-stakes deployments in finance, healthcare, and defense.
