Is Virology Capabilities Test (VCT) still meaningful?
Status:Still useful Checked against the report, 5 November 2026
Verdict
Yes, as a warning signal. A high paper score may not mean real-world uplift.
Why still useful: The chapter lists it as active: o3 scored 43.8% in 2025, above 94% of experts.[1][1] Virology Capabilities Test, arXiv 2504.16137 Primary
What “Still useful” meansKnown problems
- The authors of a wet-lab trial flag a gap between paper benchmarks and the physical lab.[2][2] Wet-lab uplift trial, arXiv 2602.16703 Primary
- SecureBio co-developed xAI's bio/chem benchmark and licenses VCT to several labs.[3][3] xAI, Risk Management Framework (20 Aug 2025) Primary[4][4] SecureBio, AI: 2025 in Review Vendor
