Codex for typical product tasks.
OpenAI's agent reads your repository, runs commands and closes tasks from a bug fix to a ready pull request. It is especially strong in Python, JavaScript, TypeScript and the web stack.
Claude Code for large contexts and refactoring.
A good fit for big monorepos, architectural changes and tasks where a single edit has to be carried carefully through many related files.
OpenCode for control over the model and the pipeline.
The open-source approach lets you plug in your own provider and build the agent into your existing development infrastructure without being tied to one vendor.
Octodus picks the tool for the task.
Small features and bug fixes can go to Codex or OpenCode, a large refactor to Claude Code. Your team sets the task instead of administering three separate products.
