OpenAI is reportedly developing a new coding model named GPT-5.1-Codex-MAX, aimed at enhancing software development for larger projects and long-term tasks. Early insights indicate that this model is designed to outperform existing coding assistants, particularly in managing extensive code repositories that surpass current context limits. By focusing on project-scale workloads rather than isolated coding tasks, OpenAI aims to overcome challenges faced by models that struggle to comprehend large codebases. Unlike existing solutions, such as Anthropic’s Claude MAX with its 500k context window, the new model may utilize faster computing and innovative architectural changes to better navigate complex repositories. This initiative suggests that OpenAI is attempting to fill a significant gap in AI-assisted software engineering, potentially elevating expectations in the field. With the competitive landscape intensifying, especially in light of the Gemini 3 launch, the anticipated rollout of GPT-5.1-Codex-MAX could be imminent, possibly within days.
