"This launch, at its core, is about taking our existing agents SDK and making it so it's compatible with all of these sandbox providers," Karan Sharma, who works on OpenAI's product team, told TechCrunch.
The core appeal of the Codex app is its ability to multitask. Instead of talking to one AI at a time, developers can run multiple coding agents in parallel. Each task is kept in its own "worktree," meaning the agents can tinker with the code simultaneously without creating a tangled mess of conflicting changes.
