Codex 0.161.0

Codex 0.161.0 makes GPT-6.1 Sol the default model in its bundled and Amazon Bedrock catalogs.

You can also sign in to an MCP server from an active terminal session with /mcp login <name>, and choose your microphone, speaker and microphone input channels for voice conversations. Voice preferences are saved locally.

Daybreak now requires explicit opt-in through --enable cli_daybreak or features.cli_daybreak=true. Setting daybreak=true alone isn’t enough. Without opt-in, its controls and /daybreak are unavailable, and automatic Cyber routing is omitted even for saved Daybreak threads. Saved preferences remain intact.

Opt-in routing requires an eligible ChatGPT sign-in, the OpenAI provider and advertised model/program support.
