OpenAI is rolling out a new model called GPT-5.2-Codex-Max for subscribers, which enhances the capabilities of its Codex tool. This version improves performance on long tasks, tool use reliability, and understanding of visual content, building on the features introduced in GPT-5.2. Further details about the model are expected to be released soon.

ChatGPT has introduced a new feature in its "GPT-5 Thinking" that allows users to select between different reasoning modes: Standard, Extended, Light, and Heavy, depending on their needs and account type. While most users may not need to adjust these settings, advanced users can benefit from greater control over the AI's output speed and depth of reasoning, enhancing their workflow efficiency.

OpenAI has introduced significant upgrades to Codex, making it faster and more reliable for developers. The new GPT-5-Codex is optimized for real-world coding tasks, enhancing collaboration and code review capabilities while integrating seamlessly with various development environments.
