OpenAI has expanded access to its Codex AI models, making them available to Plus users in addition to Pro users. The Codex models, including the o1 Pro and Codex Mini, are now integrated into TypingMind, a platform that offers AI-assisted typing tools. Early feedback from Pro users highlights the enhanced capabilities of Codex, described as "Codex on steroids," indicating improved performance and functionality. This rollout marks a broader availability of Codex technology beyond the initial Pro user base.
