OpenAI has introduced GPT-5.4-Cyber, a purpose-built variant of GPT-5.4 tuned to assist vetted security professionals with tasks previously reserved for specialized analysts.

OpenAI Brings Plugins to Codex, Narrowing the Gap with Claude Code

OpenAI has quietly expanded Codex’s capabilities by adding a plugins system — a move that makes the coding assistant feel less like a standalone tool and more like a configurable platform.
