Google launches a MUM- Multitask Unified Model


Recently, Google announced a new artificial-intelligence system called MUM, which stands for Multitask Unified Model.

  • Google’s Multitask Unified Model (MUM) update landed in June 2021, seeking to deliver search results that overcome language and format barriers to deliver an improved search experience
  • The Google MUM update uses an innovative solution that accesses a wealth of previously hidden information around a core query, providing more of what we want without having to carry out multiple different searches
  • Google MUM can understand and translates 75 different languages, including text and images

MUM has the potential to transform how Google helps you with complex tasks. MUM uses the T5 text-to-text framework and is 1,000 times more powerful than BERT.  MUM is multimodal, so it understands information across text and images and, in the future, can expand to more modalities like video and audio.

The Google Multitask Unified Model (MUM) update uses an AI-powered algorithm to improve online search capability. 

MUM has the ability to understand and bring solutions based not just on textual content but also an interpretation of images, videos, and podcasts in a way that was never possible before.

Language can be a significant barrier to accessing information. MUM has the potential to break down these boundaries by transferring knowledge across languages. It can learn from sources that aren’t written in the language you wrote your search in, and help bring that information to you. 


Google is expected to analyze multiple sources and find answers to all the questions that are of interest to users. With MUM, robots are supposed to scrutinize content not only in the source language which should enable using multiple sources and providing even more accurate answers. 

So, what will change for websites and content marketing?

MUM technology is going to be based on multilingual sources, so websites are likely to reach Internet users from all over the world, not only those who enter queries in their native language.

We don’t know yet when MUM will be implemented but  it’s recommended to focus on creating high-quality content that provides answers to all queries that may be related to a given issue.
