OpenAI Codex CLI — October 2026 Releases
9 releases in October 2026.
What's new in OpenAI Codex CLI, 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.
