Model settings keep only the latest model in each family, and add Grok 4.7
Settings now offer Claude Opus 5.5, Sonnet 5.5, and Fable 5.1 on both engines and OpenRouter, GPT-6.1 Sol, GPT-6 Luna, GPT-6 Astra, and `xai-oauth/grok-4.7`; older generations are deprecated.
Deprecated models still run wherever a repository file or saved preference already names them, so nothing stops working today, but the settings dropdowns and the published .sinatrarc schema no longer list them. On claude-code the new names are opus-5-5 and sonnet-5-5, and the engine's default moves from sonnet (Sonnet 4.6) to opus-5-5. Unconfigured runs move too: a Codex subscription falls back to openai-codex/gpt-6.1-sol until we have your account's model list, and skips deprecated models on it, and a lone OpenRouter key now defaults to openrouter/anthropic/claude-opus-5.5 at medium effort.
