Roblox, the popular online gaming platform, has introduced a groundbreaking feature that revolutionizes communication in the metaverse. Through the development of an in-house large language model (LLM), Roblox now offers real-time AI translation, enabling seamless conversations among users speaking different languages.
Announced by Roblox’s chief technology officer, Dan Sturman, on February 5th, this innovative translation system facilitates instantaneous communication, even across language barriers. Sturman emphasized the significance of this advancement by illustrating scenarios where players, unbeknownst to each other, converse in different languages while enjoying shared experiences within Roblox.
The AI-powered translator currently supports 16 languages, ensuring that users can engage in text-based conversations effortlessly. What sets Roblox’s unified translation model apart is its ability to deliver rapid translations with a base latency of just 100 milliseconds, providing a seamless chatting experience.
The development of this translation feature posed significant challenges, primarily in designing a system capable of independent translation across all supported languages in real-time. To overcome this, Roblox devised a transformer-based translation LLM, consolidating all language pairs into a single model. By employing a mixture of expert translation apps and leveraging both public and private data, Roblox trained the model to comprehend nuances in various languages, including slang terms.
Moreover, the system underwent rigorous testing and refinement to ensure the accuracy and understandability of translations. Human evaluators played a crucial role in fine-tuning the model, continuously updating it with the latest phrases and slang terms.
Initial testing revealed promising results, with the translation feature driving increased engagement and session quality among Roblox users. With 70 million daily active users spanning over 180 countries, Roblox continues to innovate, aiming for seamless communication and enhanced user experiences within the metaverse.
Roblox’s latest advancement underscores its commitment to fostering inclusivity and connectivity in the digital realm. As the metaverse evolves, Roblox remains at the forefront, spearheading transformative initiatives that shape the future of online gaming and virtual communities.
