OpenAI is distributing Codex as a plugin within Claude Code, placing its code model inside a competitor’s IDE. The move prioritizes API revenue and developer lock-in over the walled-garden strategy typical of AI labs. Rather than force developers to choose between tools, OpenAI is making Codex a utility layer that works anywhere, converting switching costs into switching benefits. AI tooling is maturing toward compatibility and interoperability over exclusive ecosystems.
