Codex Has Left The Laptop | DevDay 2026
Summary
The presentation details the evolution of Codex from handling individual tasks to delegating complex, multi-stage problems to advanced agents. Key advancements include the launch of Codex Cloud, which allows agents to run tasks in managed, cloud-based environments, eliminating the need for local infrastructure upkeep. Furthermore, Codex is being integrated across multiple interfaces (CLI, Web, Slack, Teams), ensuring developers can use the same agent and tools regardless of where they are working.
Key takeaways
-
Codex Cloud for Infrastructure Management
3:50
Codex Cloud allows users to run tasks in managed environments, eliminating the need to maintain local machines or VPSs. The system automatically handles repository inspection, dependency setup, and writes necessary startup scripts and skills. It supports private resource access using mechanisms like Tailscale (VPN access) and OIDC, ensuring secure connectivity to non-public APIs.
-
Omnichannel Agent Access
6:10
The same core agent is now accessible across multiple platforms, including the desktop app, CLI, web interface, Slack, and Teams. This consistency allows developers to continue work (e.g., reviewing code, testing shaders) seamlessly across different interfaces.
-
Enhanced Collaboration and Planning with Space
14:00
The 'Space' feature centralizes planning and collaboration, allowing teams to share plans, get feedback, and let Codex continuously update progress directly within a document, keeping all team members synchronized on project status.
-
Productivity with 'My Dot'
18:20
The 'My Dot' feature acts as a personalized, ongoing agent extension of the developer. It can monitor specific channels, proactively review Pull Requests (PRs), and initiate full cloud tasks based on ongoing work, minimizing manual prompting.
Technical details
-
Codex Cloud Environment Setup
230s
When setting up a new cloud environment, Codex inspects repositories and dependencies, automatically generating a startup skill and a startup script. The system can detect dependencies (e.g., iOS and web) and correctly identify limitations (e.g., running mobile apps in a Linux environment). The platform improves speed via file system snapshotting and supports background updates.
-
Secure Network Access
430s
Cloud environments can be configured to access private resources that are not exposed to the public internet. This is achieved by integrating services like Tailscale (using an off-key) and supporting OIDC for secure resource access.
-
CLI and Web Overhauls
1250s
The Command Line Interface (CLI) now includes an 'agent view' to monitor and manage multiple running tasks in parallel. The web interface provides direct access to running cloud tasks, allowing interaction with deployed sites and reviewing video outputs without needing the desktop app.
-
Code Review and Iteration
700s
The desktop app was overhauled to include a dedicated code review tab for PRs assigned to the user or created by them. Users can run a review with Codex and ask direct questions about the PR's purpose and potential side effects.
