Limited Access to Cyber: OpenAI Follows Anthropic's Lead

Colleagues, I want to highlight a cybersecurity development: OpenAI is implementing restricted access to GPT‑5.5 Cyber.

Key facts I noted:
- Access will be granted to “critical defenders” by application with verified qualifications.
- The tool is designed for penetration testing, vulnerability discovery and reverse engineering.
- Concern: this feature set could be abused by malicious actors.

Why it matters: the trade-off between openness and safety directly affects infrastructure protection.

How do you assess this access model?
