OpenAI Codex with Ollama (ollama.com)

OpenAI has integrated its Codex CLI with Ollama, enabling the use of open-weight models for code manipulation directly within a local environment. This new collaboration allows users to execute commands that leverage models such as gpt-oss:20b and gpt-oss:120b, enhancing accessibility for developers looking to implement generative AI capabilities in their workflows. Users can get started easily by installing the Codex CLI and using specific commands to modify and execute code in their working directories. This development is significant for the AI/ML community as it democratizes access to powerful code-generating models, allowing more developers to utilize advanced AI in their projects without being limited to proprietary solutions. The integration emphasizes the importance of large context windows—at least 32K tokens are recommended for optimal operation—which is crucial for understanding and generating complex code. Furthermore, users can switch between local and cloud models seamlessly, broadening their options for leveraging AI in software development. For detailed setup and configuration, OpenAI has provided a comprehensive integration guide.
