Image from OpenAI Codex 0.137.0: Enterprise Credit Limits, Multi-Agent v2, and Remote Control Pairing
OpenAI's June 4 Codex CLI release brings enterprise admin flows with monthly credit limits, a rebuilt multi-agent system, remote-control pairing via app-server v2 RPCs, and parallel web searches.
OpenAI released Codex 0.137.0 on June 4. The full release notes are on GitHub. This one is mostly an enterprise and platform story, with two notable feature additions: a rebuilt multi-agent system and a new remote-control pairing flow.
Enterprise Credit Limits and Managed Config Bundles
Enterprise and admin flows now display monthly credit limits directly in the interface. Admins can also apply cloud-managed config bundles, including workspace configs for education environments.
This is part of a broader push to make Codex deployable at scale in managed environments, where IT needs visibility into spend and standardized configs without relying on individual developers to maintain settings.
Multi-Agent v2
The multi-agent system got a substantial rebuild. The key change: each spawned agent thread now keeps its own runtime model choice. In the previous system, sub-agents inherited the parent’s model selection in ways that were difficult to control. Now the model persists per-thread, which makes it easier to run different agents with different models in the same workflow.
The release also cleans up follow-up and metadata defaults for spawned agents, making the API more predictable when building automated pipelines.
Remote-Control Pairing
Remote-control clients can now pair with Codex sessions, list active controller grants, and revoke them, all through the new app-server v2 RPC endpoints. This is aimed at IDE integrations and external tooling that wants to connect to a running Codex session without requiring a full local install.
The remote-control story in Codex has been building for a few releases. The v2 RPC layer gives it a more stable foundation than the earlier implementation.
Plugin Workflow Improvements
codex plugin list --json now outputs machine-readable JSON, which makes plugin management scriptable. The command also returns cached remote catalog suggestions, so you can see available plugins without a live network request every time.
TUI and Search Updates
A handful of smaller additions round out the release. The TUI now supports F13-F24 keybindings and paste in searchable menus. Hosted web and image tools are available in more code-mode flows, and standalone web searches can now run in parallel, which cuts down wait time when a task needs multiple lookups.
A useful bug fix for anyone who has been caught by this: cancelling a submitted prompt before any visible output now restores your draft, attachments, and collaboration mode for editing, rather than discarding everything.
