Which one should carry your traffic?
If Nemotron 3 Ultra answers your requests as well as Gemini 3.1 Pro Preview, moving that traffic saves 75% on chat-shaped requests. Averages cannot tell you whether it does for your requests. Nemotron 3 Ultra does not expose a confidence signal through OpenRouter, so Gimbix would test it as a full replacement rather than a first answer.
