Microsoft Chief Scientific Officer Eric Horvitz discusses the Paraphrase project on the Health Wanted podcast—a cross-industry effort joining Microsoft, OpenAI, Anthropic and others to address biosecurity risks from rapidly improving AI.
Key points:
- Large language models are approaching the capability threshold where bad actors could weaponize them for bioterrorism
- AI companies are building shared defenses—early warning systems and access controls—to prevent misuse
The 52-minute episode frames this as an industry-wide collective defense initiative that crosses competitive lines.
