OpenAI Releases GPT-6 Cyber With Restricted Access for Defenders

The restricted launch gives vetted defenders a stronger vulnerability research tool, with reported findings and access controls that require separate assessment.

San Francisco, 6 November 2026 – OpenAI released GPT-6 Cyber to a limited group of vetted users on 5 November, giving authorised security teams access to a model built to find and validate software vulnerabilities. The company classified it as Critical for cybersecurity under its own Preparedness Framework. It said the model helped identify 81 previously unknown flaws that Mozilla classified as high severity in Firefox.

For Asian companies that build or depend on widely used software, faster vulnerability discovery could shorten the interval between finding a weakness and fixing it.

Neither the rating nor the reported results should be mistaken for an independent assurance of safety.
