OpenAI Codex – 2025 the year of AI agents continues

OpenAI introduced recently CodexAI:

A cloud-based software engineering agent that can work on many tasks in parallel, powered by codex-1. Available to ChatGPT Pro, Team, and Enterprise users today, and Plus users soon.

Getting Started with CodexAI Docker Image

OpenAI provides a reference implementation of the base Docker image, available on GitHub: https://github.com/openai/codex-universal/ .

The Docker image comes preloaded with a wide range of programming languages and tools, making it ideal for polyglot development:

• Python
• Node
• Bun (Node.js-compatible package manager)
• Java
• Swift
• Ruby
• Rust
• Bazel

Running the Docker Image on Linux

Here’s how I ran the Codex Universal image on my Linux machine:

$ uname -v && \
cargo version && \
docker run --rm -it \
-e CODEX_ENV_RUST_VERSION=1.87.0 \
-v "$(pwd)":/workspace/"$(basename "$(pwd)")" \
-w /workspace/"$(basename "$(pwd)")" \
ghcr.io/openai/codex-universal:latest

Example output:
