Multilingual AI support bots require sophisticated routing, not just translation

Building multilingual support bots, especially for regions like Southeast Asia, presents a complex routing challenge rather than a simple translation task. Key issues include accurately detecting language when users code-switch, understanding that different languages require different model sizes (e.g., larger models for Arabic or Tamil compared to English), and implementing per-step routing within a single conversation turn to use appropriate model tiers for tasks like classification versus synthesis. Furthermore, data residency regulations, such as Singapore's Personal Data Protection Act, necessitate in-region inference, which aligns with latency requirements for natural conversation. AI

IMPACT Optimizing AI model routing and tiering can significantly reduce operational costs and improve user experience for multilingual applications.

    Language is a routing problem, not a translation problem

    <p>Most teams approach a multilingual support bot as a translation problem. Wire up a translation layer, send everything to one big model, done. We did roughly that the first time, and it mostly worked — until we looked at the bill and at which customers were actually being serve…
