Gemini 4 Argon biological capabilities evaluation
Gemini 4 Argon Biology Capabilities Assessment
A third-party evaluation by SecureBio shows that Gemini 4 Argon scored 169 on the Bio Capabilities Index, ranking second among 97 evaluated models, behind only Claude Opus 5 (176). On the BioTIER benchmark, it refused 87.8% of dangerous biological questions, higher than Gemini 3.1 Pro's 62.8%, and correctly allowed 97.6% of benign questions; it scored 57.3%±0.9% on VCT-v2, close to GPT-6 Astra's 58.0%. Google DeepMind's pre-release safety report states that with production guardrails disabled, it cannot be ruled out that the model reaches CBRN Uplift Level 1, and the external evaluation organization Faculty Science estimates that it could save a specific threat actor up to months of trial-and-error research.
SecureBio uses its own biological capabilities benchmark to give specific scores and refusal rates for Gemini 4 Argon, allowing horizontal comparison with frontier models such as Claude Opus 5.
