AI models translate differently: one keeps closer to your sentences, another reads more freely. While your style bible waits for approval, you can have each model the studio offers translate the first lines of your voice chapters, about 600 words, with that style bible.
The translations appear side by side as A, B and C, without the models' names, so you judge them by how they read. Pick the one you like best: the voice chapters and the rest of the book are translated with it. The editor's pass and the checks stay as they are.
What it costs: each model's lines at the draft rate, $0.30 per 1,000 words, about $0.18 a model. It isn't part of the translation's price, and you can compare again before you approve the style bible.
