OpenAI has introduced a new ai system, gpt-red, which is designed to test the security of its own ai models by attacking them. This technology is intended to identify vulnerabilities that may have been missed by human testers, and it appears to have already improved the defensive capabilities of gpt-5.6. The introduction of gpt-red is part of a broader effort to enhance cyber defense, although the exact scope and details of this initiative are not entirely clear.
