OpenAI Codex training in Berlin

Delegate development work with OpenAI Codex: CLI and cloud agent, AGENTS.md, sandboxing, approvals and team PR workflows.

All 32 OpenAI Codex courses are also available in Berlin – in a centrally located training room or at your premises on request.

OpenAI Codex is a coding agent that runs both locally, as a command-line tool and IDE extension, and as a cloud agent. Locally, Codex reads your repository, proposes changes and runs commands inside a sandboxed environment. In the cloud, it works on delegated tasks in parallel inside isolated containers and returns results as traceable diffs or pull requests. Over two days you will learn how to combine both modes effectively and how to scope tasks so that the agent can complete them reliably and with minimal back-and-forth.

Berlin is Germany’s capital of start-ups, agencies and digital teams. Our training room is conveniently located in the city centre – ideal for product teams, developers, associations and public authorities who want to learn AI and agentic coding hands-on.
