What's new in OpenAI Codex CLI

November 2026: OpenAI Codex CLI adds an agent command center, backend switching and Vertex AI setup

So far in November 2026, OpenAI Codex CLI added an agent command center, backend switching that keeps drafts, and a Google Cloud Vertex AI setup wizard. Two releases have shipped, from rust-v0.167.0 to rust-v0.167.1.

The command center opens with codex agents --no-daemon, and both it and the session picker now mark unread results. In the terminal session picker you can switch between connected backends without losing your drafts. Local image attachments can be previewed while composing on supported terminals. Under "Sign in another way", enabling gcpsetupwizard sets up Vertex AI with Application Default Credentials or a credential file. System proxy settings for macOS or Windows can be enabled from /experimental.

The follow-up rust-v0.167.1 adds opt-in incremental tools for regular OpenAI Responses and restricts legacy incremental tools to Amazon Bedrock providers. Fixes in v0.167.0 cover saved chats staying visible after a provider switch, Ctrl+L clearing the display while Ctrl+T keeps earlier messages, and network approval prompts closing when their requests end.

• Agent command center opens with codex agents --no-daemon; it and the session picker mark unread results (rust-v0.167.0)
• Switch connected backends from the terminal session picker and keep your drafts (rust-v0.167.0)
• gcpsetupwizard enables Google Cloud Vertex AI setup via Application Default Credentials or a credential file (rust-v0.167.0)
• Preview local image attachments while composing on supported terminals (rust-v0.167.0)
• Opt-in incremental tools for regular OpenAI Responses; legacy ones limited to Amazon Bedrock (rust-v0.167.1)
• Opt into macOS or Windows system proxy settings from /experimental (rust-v0.167.0)

October 2026: OpenAI Codex CLI adds /presets, mid-turn steering, a Vertex AI provider and GPT-6.1 models

OpenAI Codex CLI in October 2026 changed how you interact with a running session and added more model providers. Nine releases shipped, from rust-v0.160.0 to rust-v0.166.0. You can now send a follow-up while Codex is responding to steer it, set a leader key in /keymap, search and change settings in /config, and restart a managed background server from /daemon. Ten numbered /presets slots save reusable prompts, and /model and /permissions accept inline arguments.

On models, GPT-6.1 Sol became the default in the bundled and Amazon Bedrock catalogs, GPT-6.1 Terra was added later, and a built-in Google Cloud Vertex AI provider arrived (model_provider = "gcp"). /mcp login <name> signs in to MCP servers from a terminal session. Memory v2 is now on by default for fresh profiles. The rest of the month was fixes for Windows sandboxing, session resume permissions, network proxy checks and TUI crashes, plus two quick patch releases.

• Send a follow-up while Codex is responding to steer it immediately (rust-v0.163.0)
• Ten numbered /presets slots for reusable prompts, plus inline /model and /permissions arguments (rust-v0.164.0)
• Built-in Google Cloud Vertex AI provider, configured with model_provider = "gcp" (rust-v0.165.0)
• GPT-6.1 Sol becomes the default model; GPT-6.1 Terra is added to the catalogs (rust-v0.161.0, rust-v0.165.0)
• Sign in to MCP servers from a session with /mcp login <name> (rust-v0.161.0)
• Keyboard-driven transcript selection with search, and codex doctor --network-only for diagnostics (rust-v0.166.0)
