Which one should carry your traffic?
If Hy4 preview answers your requests as well as GPT-6 Astra, moving that traffic saves 93% on chat-shaped requests. Averages cannot tell you whether it does for your requests. Hy4 preview does not expose a confidence signal through OpenRouter, so Gimbix would test it as a full replacement rather than a first answer.
