According to @OpenAI on X, new Codex capabilities are rolling out today to ChatGPT Pro users in the Codex app, CLI, and IDE extension, enabling integrated code generation and automation within developer workflows (source: OpenAI post on X, Feb 12, 2026). As reported by OpenAI’s announcement, the distribution across command line and IDE surfaces suggests faster prototyping and reduced context‑switching for teams adopting AI pair‑programming, with immediate productivity gains in code completion, refactoring, and test generation. According to OpenAI’s post, ChatGPT Pro subscribers gain first access, indicating a monetization path where enterprises can pilot AI coding assistants organization‑wide via managed IDE rollout and CLI scripting. As reported by OpenAI, the multi‑surface release positions Codex as a full‑stack developer copilot, creating opportunities for SaaS vendors and DevOps platforms to embed AI-assisted code actions, CI hooks, and secure review flows through IDE and terminal plugins.

According to OpenAI, the Codex app is now available for macOS users, with a Windows version set to launch soon. For a limited period, Codex can be accessed through ChatGPT Free and Go subscriptions, offering broader availability for developers and businesses. Additionally, OpenAI is doubling the rate limits for Plus, Pro, Business, Enterprise, and Edu users across the Codex app, CLI, and IDE platforms, enhancing efficiency for high-demand workloads. This expansion is expected to drive increased adoption of Codex-powered workflows and AI code generation tools, particularly for organizations seeking scalable AI coding solutions, as reported by OpenAI via Twitter.
