+- **feat(codex):** Add GPT-6.1 Sol to the stable fork's OpenAI and Codex catalogs, preserve Max/Ultra routing and tool calls, accept Responses model imports, and align the Codex client profile and optional Docker CLI at 0.159.2. Include Standard short-context price estimates and the purchased-credit Fast multiplier; adapt upstream [#15171](https://github.com/diegosouzapw/OmniRoute/pull/15171) and [#15158](https://github.com/diegosouzapw/OmniRoute/pull/15158) — thanks @xiaoyaner0201 and @HouMinXi.
