Roblox has developed its own AI model for swift translation
of text in chats, so users can understand each other beyond the language
barrier. The technology can translate the messages exchanged between users in 16
languages, including English, French, Japanese, Thai, Polish, and
The model is built on Roblox’s own large language model
(LLM) that it has trained on internal, publicly available data. Instead of
creating an LLM for each language, Roblox integrated the LLM within a Mixture
of Experts (MoE) architecture, that ran multiple translation apps, each of
which was an expert in one language.
Roblox’s AI translator automatically translates messages as they come in, and users can also see the original text by clicking on an icon. You can also provide feedback to the translator if you find its translations to not be very accurate.
This is not the first time that Roblox has incorporated AI in
its platform – only last year, the company rolled out an AI chatbot assistant
for developers. Another AI feature in Roblox translates image assets, like
words on buildings, to the user’s default language.
Roblox CTO Dan Sturman states that the company would
continue to explore other many possibilities with AI, such as using the
technology to translate banned words to acceptable ones or for real-time voice
