Repository navigation
Always uses the newest model in each family, and finds it by itself.
- Newest model, automatically. Routing now names model lines (Codex Sol, Luna and Astra, the Grok base model, the Claude aliases) instead of fixed model ids. The routing card picks the newest release this account can see. Today that is GPT-6.1 Sol, not the older GPT-6 Sol. A newer release in a known line is used after one quick test call. A brand-new kind of model is researched first. Older releases are never used, including through remembered answers.
- Never hands work to Astra or Fable on its own. Codex Astra (any version) and Claude Fable are never a default, backup, escalation or option. They are used only if you ask for one and then confirm again once the cost is named. The Codex launcher refuses any Astra id without that approval.
- Jev finds its newest release (Jev 1.14 today) and records which one answered.
- Evidence refreshed to October 2026: GPT-6.1 Sol, Claude Sonnet 5.5 and Haiku 5.5, Grok 4.7, Jev 1.14.
- Tested on real runs. 13 scenarios, each run by a real Claude Opus 5.5 lead, all passed on their latest run. No run sent work to a premium model or used an outdated one. These are single runs, not a success rate.
