Overview
The cross-vendor mode sends council work through OpenRouter, which provides access to multiple LLMs. One run includes responses from GPT, Gemini, an Opus model, and Grok, with an additional model used in a reviewer role.
The models produce separate answers, and the workflow combines them through the council's review process. The user can inspect each model's contribution rather than receiving an opaque final answer with no indication of which models participated.
The motivation is that different models often respond in different ways and may be stronger at different kinds of work. A cross-vendor council uses that variation as part of the deliberation process.
