Jeff Nash	fcb0293c0d	feat(registry): add GPT-5 Codex Mini model variants Adds three new Codex Mini model variants (mini, mini-medium, mini-high) that map to codex-mini-latest. Codex Mini supports medium and high reasoning effort levels only (no low/minimal). Base model defaults to medium reasoning effort.	2025-11-07 17:07:39 -08:00
