Which one should carry your traffic?
If Mistral Small 4 answers your requests as well as Grok 4.7, moving that traffic saves 89% on chat-shaped requests. Averages cannot tell you whether it does for your requests. Mistral Small 4 does not expose a confidence signal through OpenRouter, so Gimbix would test it as a full replacement rather than a first answer.
