Biological static hazard evaluation
Gemini 4 Argon 0.13% Only in system cards Models answer 75 questions across priority biological threat scenarios, each asked 10 times. The score is the share of hazardous responses.
In-house Google DeepMind evaluation run without out-of-model safeguards.

Gemini 4 Argon leads with 0.13%
Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

Scores over time
All the scores we have, one dot each, so a model tested at several settings appears more than once.
Labs report it only in system cards
We read the headline results of 479 launch posts from 51 labs, and none of them list this benchmark. Some system cards do, below.
One system card reports it
Besides launch posts, we read the system cards, model cards and technical reports labs publish with a release. They report far more, including safety and frontier-risk tests.

|---|---|---|---|---|
| 13 Oct 2026 | Gemini 4 Argon system card | 0.13 | Additional static evaluations, biological, hazardous response rate 1/750 (0.13%), Model B without out-of-model safeguards (3.2.1.5) | Bio and chem risk |
