Which one should carry your traffic?
If Phi 4 answers your requests as well as gpt-oss-120b, moving that traffic saves 64% on chat-shaped requests. Averages cannot tell you whether it does for your requests. Phi 4 does not expose a confidence signal through OpenRouter, so Gimbix would test it as a full replacement rather than a first answer.
