LatchBio evaluated Grok’s performance on biosecurity monitoring and adversarial biological tasks. They found that Grok 4.6 correctly detects and refuses dangerous queries, including maliciously obfuscated biological tasks, while also allowing beneficial scientific queries to be answered. We discuss these results in a blog post: ↧ Biosecurity at the frontier LatchBio evaluated Grok's performance on biosecurity monitoring and adversarial biological tasks. They found that Grok 4.6 detects and refuses dangerous queries more reliably than any other frontier system.
