Codex CLI 0.154.0 adds experimental worktree support and GPT-6-Astra integration
OpenAI
OpenAI shipped Codex CLI 0.154.0 on Sept 9. It adds experimental isolated checkouts via --worktree / /worktree for new or forked sessions, puts GPT-6-Astra in the model picker and Amazon Bedrock catalogs, and lets you answer Codex's inline questions without losing your draft. Windows sessions can now share a background Codex server with daemon lifecycle commands, and fixes cover MCP OAuth refresh coordination, plugin/skill refresh after upgrades, and macOS sandbox input injection.
Why it matters
Worktree isolation lets multiple Codex sessions run against the same repo without clobbering each other — the pattern Claude Code popularized arriving in Codex.
