Codex `rust-v0.140.0` adds `/usage` views, Claude Code import, and session deletion
OpenAI's Codex CLI `rust-v0.140.0` ships `/usage` token-activity dashboards, Claude Code config import via `/import`, permanent session deletion, managed Amazon Bedrock authentication, and a unified `@` mentions menu, alongside MCP reliability fixes and performance improvements for large repos.
Score breakdown
The `/import` command creates a direct migration path from Claude Code into Codex, while the new Bedrock authentication and encrypted credential storage extend Codex's reach to AWS-managed deployments.
- 01New `/usage` views show daily, weekly, and cumulative account token activity
- 02New `/import` command selectively imports setup, project config, and recent chats from Claude Code
- 03Permanent session deletion added via `codex delete`, `/delete`, and app-server `thread/delete` with confirmation safeguards
Codex `rust-v0.140.0` is a substantial feature release. The new `/usage` views surface daily, weekly, and cumulative account token activity. The `/import` command lets users selectively bring in setup, project configuration, and recent chats from Claude Code. Permanent session deletion is now available through `codex delete`, the `/delete` slash command, and the app-server `thread/delete` API, all gated behind confirmation safeguards with subagent cleanup. The `@` key now opens a unified mentions menu covering files, plugins, and skills by default, and `/goal` has been updated to preserve oversized text, large pasted blocks, and image attachments — including in remote app-server sessions. Managed Amazon Bedrock API-key authentication is also new, with encrypted local storage covering CLI and MCP OAuth credentials.
On the bug-fix and reliability front, corrupted SQLite state databases are automatically backed up and rebuilt from rollout data.
On the bug-fix and reliability front, corrupted SQLite state databases are automatically backed up and rebuilt from rollout data. MCP reliability improves through retried transient startup failures, reporting of unusable OAuth credentials as logged-out, and preservation of explicitly disabled servers. The `/review` command no longer crashes when `Esc` is pressed with queued guidance, and non-TTY background commands can now be interrupted with Ctrl-C while preserving their final output and exit status. Performance for large repositories and long sessions is improved by preserving Git's built-in filesystem monitor, avoiding duplicate history reads, accelerating archive lookup, and caching turn-diff rendering. The experimental `/realtime` voice controls and related audio dependencies have been removed from the TUI.
