OpenAI releases Codex CLI 0.161.0 with GPT-6.1 Sol as the default model

Event: Oct 7, 2026 · Published: Oct 8, 2026

On October 7, 2026 OpenAI published version 0.161.0 of its open-source Codex CLI on GitHub. The release notes say GPT-6.1 Sol is now the default model in the bundled and Amazon Bedrock catalogs, and that Amazon Bedrock supports multi-agent V2 and Ultra reasoning on compatible models. The notes also add a /mcp login <name> command for signing in to MCP servers from an active terminal session, and make Daybreak opt-in through --enable cli_daybreak. USASI has not tested these changes.1
