New Model Enhances Developer Productivity with Improved Coding Performance and Extended Context
OpenAI has unveiled GPT-5.1-Codex-Max, the latest addition to its Codex series designed to assist developers with complex coding tasks, offering faster adaptive reasoning, enhanced multitasking, and superior accuracy for long-running projects.
GPT-5.1-Codex-Max builds on previous Codex models by integrating improvements in code generation, review, and question-answering capabilities specifically tailored for professional software engineering workflows.
The model is optimized for large-scale coding projects, capable of maintaining extended prompt contexts and delivering accurate, context-aware assistance across multiple programming languages.
OpenAI has made GPT-5.1-Codex-Max available gradually to GitHub Copilot users on various platforms including Visual Studio Code, JetBrains IDEs, and Xcode, ensuring seamless integration into existing developer environments.
Enhanced features include reduced token consumption for inference, enabling developers to work more efficiently with fewer interruptions or constraints in API usage.
The rollout coincides with OpenAI’s push to solidify its position in the competitive AI-assisted software development market, following the recent GPT-5.1 general release.
Developers have praised earlier Codex versions for boosting productivity, and the new Max model is expected to further accelerate software engineering workflows and innovation capacity.
OpenAI continues to iterate and refine these models based on user feedback, promising continuous updates to maintain cutting-edge performance.
GPT-5.1-Codex-Max is part of OpenAI’s broader strategy to democratize AI-powered development tools and empower developers worldwide.
