AI Translate is the premium translation option on ArkAPI. It is meant for cases where the cheap utility translator is too literal and you want more natural wording, better sentence flow, or a more polished result.
ArkAPI AI Translate uses the managed AI backend to produce higher-quality translations than the standard utility endpoint. It keeps the request simple but gives you style control when tone and readability matter. If you only need cheap workflow translation, the regular Translate API is still the faster low-cost option.
Choose /api/ai-translate when translation quality matters more than minimum cost. If you just need fast utility conversion for a workflow, /api/translate is still the cheaper default.
