OpenAI has launched Codex AI software engineering agent as a research preview to compete with other AI coding tools like Windsurf and Cursor.
Unlike the previous Codex model, the new version is a cloud-based AI software engineering agent capable of executing multiple development tasks in parallel.
The new Codex is available for ChatGPT Pro, Enterprise, and Team users, with support for Plus and Edu users expected in the future.
It marks a significant advancement from the original Codex model, which focused on code generation and completion.
The new Codex can write features, fix bugs, answer codebase-specific questions, run tests, and propose pull requests in a secure cloud sandbox.
OpenAI envisions Codex as a tool that can operate autonomously to accomplish substantial work by interacting with the real world.
The Codex-1 SWE agent outperforms OpenAI's latest reasoning models on internal SWE tasks.
External use cases include Cisco, Temporal, Superhuman, and Kodiak utilizing Codex for various engineering tasks.
Codex executes tasks in an air-gapped environment with human review to ensure secure operation, making it more than just a model API.
OpenAI has launched Codex CLI for local development with updated pricing plans and a free rollout period.
