OpenAI o3-mini System Card

OpenAI rates o3-mini's post-mitigation overall risk as Medium, with Medium in CBRN, persuasion, and model autonomy, and Low in cybersecurity. The post says o3-mini is the first model to hit Medium on model autonomy due to stronger coding and research-engineering performance, but it does not disclose benchmark scores and says its real-world ML self-improvement capability is still below High. The key policy gate is explicit: deployment requires Medium or below, and further development allows High or below.

Why it matters: This is an official OpenAI system card, not routine promo copy. HKR-H/K/R all pass: it discloses o3-mini's Medium post-mitigation risk, a Medium autonomy rating, and explicit deploy/develop gates. The missing benchmark scores keep it below a major model-release tier, so it fits 8
