Levels crossed

We cannot rule out that Gemini 4 Argon reaches the cybersecurity CCL.

despite claude opus 5.5’s cyber capabilities, the model still falls within the lower category of capabilities set out in our frontier compliance framework (fcf), and we do not see indications that the model is capable of novel offensive capability.

although mythos 5.1 is in tier 1, it is getting closer to tier 2, completing more and more autonomous tasks.

chem/bio: moderate or lower risk; cyber: moderate or lower risk (inferred); loss of control: moderate or lower risk (inferred).

- cyber: moderate or lower risk (inferred);

our assessments indicate that, when evaluated without mitigations applied, we cannot rule out muse spark 1.1’s capabilities meeting this threshold in both the chemical & biological and cybersecurity domains.

this is the first launch we are treating as high capability in the cybersecurity domain under our preparedness framework, activating the associated safeguards.

cybersecurity on key skills benchmark, v1 hard challenges: 11/12 challenges solved; v2 challenges: 0/13 solved end-to-end.

showed meaningful improvements in cyber capabilities, particularly in vulnerability discovery and code analysis;

ccl reached? no, but the early warning alert threshold was originally reached by gemini 2.5 pro and continues to be met by gemini 2.5 deep think.
