In the past, developers used AI tools by opening a chat window, typing a question, getting a code snippet, and manually copying it. This workflow improved efficiency, but was still essentially a linear &ldquo;question and answer&rdquo; model — the AI played the role of an on-demand assistant rather than a collaborative partner capable of taking on independent work.</p> <p>The new <strong>Codex App</strong> that OpenAI officially released in February 2026 completely changes this equation. Defined by OpenAI as the &ldquo;Command Center for Agents,&rdquo; this macOS application is powered by the GPT-5.2-Codex and GPT-5.3-Codex models — the former was described by OpenAI as &ldquo;the most advanced agentic coding model to date&rdquo; when it launched in December 2025.</p>
