Description

GPT-5-Codex-Mini provides a more resource-efficient way to code, allowing approximately four times the usage compared to GPT-5-Codex while maintaining dependable functionality for most development needs. It performs exceptionally well for straightforward coding, automation, and maintenance tasks where full-scale model power isn’t required. Integrated into the CLI and IDE extension via ChatGPT sign-in, it’s designed for accessibility and convenience across environments. When users approach 90% of their rate limits, the system proactively recommends switching to the Mini model to ensure continuous workflow. ChatGPT Plus, Business, and Edu accounts enjoy 50% higher rate limits, giving developers more capacity for sustained sessions. Pro and Enterprise plans gain priority processing, making response times noticeably faster during peak usage. The overall system architecture has been optimized for GPU efficiency, contributing to higher throughput and reduced latency. Together, these refinements make Codex more versatile and reliable for both individual and professional programming work.

Description

GPT-5.1-Codex is an advanced iteration of the GPT-5.1 model specifically designed for software development and coding tasks that require autonomy. The model excels in both interactive coding sessions and sustained, independent execution of intricate engineering projects, which include tasks like constructing applications from the ground up, enhancing features, troubleshooting, conducting extensive code refactoring, and reviewing code. It effectively utilizes various tools, seamlessly integrates into developer environments, and adjusts its reasoning capacity based on task complexity, quickly addressing simpler challenges while dedicating more resources to intricate ones. Users report that GPT-5.1-Codex generates cleaner, higher-quality code than its general counterparts, showcasing a closer alignment with developer requirements and a reduction in inaccuracies. Additionally, the model is accessible through the Responses API route instead of the conventional chat API, offering different configurations such as a “mini” version for budget-conscious users and a “max” variant that provides the most robust capabilities. Overall, this specialized version aims to enhance productivity and efficiency in software engineering practices.
