Model and session changes
Codex CLI 0.157.0 adds GPT-6 Sol and Luna to its model catalog, including Amazon Bedrock support and migration prompts for older models. The release notes identify these as CLI changes; they do not establish availability in ChatGPT.
Fullscreen transcripts are now enabled by default. Eligible interactive sessions also start the background server automatically, with recovery choices offered when server settings are incompatible.

The release makes /import available in remote sessions and local background-server sessions. It also adds an f shortcut to fork conversations open in another app while preserving drafts and queued prompts.
Terminal updates include improved rendering for Unicode bullets, checkboxes, aligned equations, and optimization notation. Shift-click can extend transcript selections.
