MinT
MinT (Machine in Translation) is a machine translation service based on open-source neural machine translation models. The service is hosted in the Wikimedia Foundation infrastructure, and it runs translation models that have been released by other organizations with an open-source license. An open machine translation service can be a key piece of the essential infrastructure of the ecosystem of free knowledge. This page captures the initiatives to scale the service and make this infrastructure more widely available.
You can try MinT as part of projects such as Content Translation and translatewiki.net, or directly in a test instance.
Overview of MinT initiatives
Machine translation can be useful in different contexts. As more products make use of MinT for different purposes, it is useful to differentiate those different contexts. In this way, when users report a bug it is more clear where it needs to be fixed.
- MinT Service. The backend service running open-source neural machine translation models.
- MinT test instance. A basic interface to try the different translation models.
- MinT for Translators. Initiative to integrate the MinT Service with tools that support other machine translaiton services such as Content Translation and the Translate Extension.
- MinT Client for Content Translation. Client exposing the MinT Service as one of the machine translation services available in Content Translation.
- MinT Client for Translate extension. Client exposing the MinT Service as one of the machine translation services available in the Translate extension.
- MinT for Wiki Readers. Product to enable readers to use machine translation to read contents from other languages on a wiki.
You can read more below about each of the MinT initiatives.

MinT Service
The MinT Service is designed to provide translations from multiple machine translation models. Currently, it uses the following models:
- NLLB-200. The latest model from the No Language Left Behind project by a research team at Meta. This model supports translation across 200 languages, including many that are not supported by other vendors.
- OpusMT. The OPUS (Open Parallel Corpus) project from the University of Helsinki compiles multilingual content with a free license to train the OpusMT translation models. Anyone can easily help improve the translation quality by participating in the different projects that contribute data to OPUS. For example, when using Content Translation to create translations of Wikipedia articles, the data on published translations will be incorporated as a new resource to improve the translation quality for the next version of the model. Another quick way to contribute is to provide sentence translations with Tatoeba.
- IndicTrans2. The IndicTrans2 project provides translation models to support over 20 Indic languages. These models were developed by AI4Bharat@IIT Madras, a research group at the Indian Institute of Technology, Madras.
- Softcatalà. Softcatalà is a non-profit organization with the goal to improve the use of Catalan in digital products. As part of the Softcatalà Translation project, translation models used in their translator service to translate 10 languages to and from Catalan have been released.
- MADLAD-400. MADLAD-400 is a multilingual machine translation model by Google Research that supports 419 languages.
MinT supports over 200 languages, with more than 70 languages not supported by other services (including 27 languages for which there is no Wikipedia yet). You can read more about the initial release of MinT and check some frequently asked questions in the summary page for the service.
Technical details
The translation models have been optimized for performance using OpenNMT Ctranslate2 library in order to avoid the need for GPU acceleration. This makes it easier for organizations and individuals to build and run their own instances. For more details you can check the following:
MinT provides a platform to run multiple translation models. In order to support different initiatives, aspects such as sentence segmentation, language detection, pre/post-processing of contents, and rich format support has been developed on top of the plain-text based models.
Test instance
The MinT test instance is a basic interface to try the different translation models. It allow to translate contents across the selected language pairs and select the preferred translation model when multiple are available. This allows different communities to check how well the models support their language. This instance is intended for testing, so performance and availability may be reduced compared to other MinT-based products. You can check the availability status of the MinT test instance.
MinT for translators
Translation is a common way to contribute in the Wikimedia ecosystem for multilingual users. Machine translation can provide a useful initial translation for users to review and improve. The Language team has developed tools to support translations in their workflows that can integrate different machine translation services to speed up their processes. Once MinT was available, integrating it with these tools was a logical next step to amplify their impact. MinT is available in the following projects:
- Content Translation. Content Translation provides guidance to create a translation of a Wikipedia article into another language.
Content Translation integrates several translation services to provide an initial translation. You can check which languages supported by MinT are available in Content Translation
- Localization infrastructure. The Translate extension provides the infrastructure used to translate our software and multilingual pages.
Communities of translators use it on translatewiki.net, Wikimedia Meta-wiki, MediaWiki.org and more.
MinT for wiki readers
The number of topics and the amount of information a reader can learn about from Wikipedia and other wikis depends on the languages they speak. Machine translation can help people to learn more about their topics of interest when the content is not available in their language.
This initiative explores how to surface the machine translation support from MinT in Wikipedia articles in a way that:
- Allows readers to learn more about the topics of interest from other languages.
- Clearly differentiates automatically generated content from community-created one.
- Encourages to access and contribute to community-created content when possible.
At the moment the Language team is working on the initial implementations for this initiative based on the research and the designs. Learnings based on data and community input will determine the next steps for the initiative.
MinT more widely available
Working on the previous initiatives will help to polish and solidify the system. For now, the MinT API is only available for Wikimedia products. As the system gets ready, we'll consider a wider exposure. Providing a service that can be used by communities in innovative ways can be a very powerful tool. New initiatives to make MinT more widely available will be captured here in the future. Meanwhile, feel free to configure your own MinT instance to experiment with it.

- Explored New advanced API for sentence segmentation to support needs for EditCheck use case and others.
- Improved responsiveness of the MinT test instance by avoiding some translation requests to get stuck.
- MinT was set as the default translation service in Content Translation for Kurdish (ku) and Sesotho (st), languages where it is optional but frequently used.
- A new larger instance has been created for the MinT. Memory quota has been increased to accommodate the needs for MinT as the usage and models available increase.
- New design concepts for exposing MinT to Wikipedia readers have been created based on input from the initial round of research.
- Published report analyzing usage of machine translation services
ottobre 2023
- MinT is now supported in Content Translation for Fon, a Wikipedia that graduated recently from incubator.
- Announced sentencex library: sentencex: Empowering NLP with Multilingual Sentence Extraction - A python and js library to meet the needs of sentence segmentation for all the languages we support.
- Proposed model card for language identification as part of the creation of a LiftWing service to provide those capabilities for MinT and others.
- The new sentence segmentation approach has been exposed in Content and Section Translation to validate it with real contents. Resolved community-reported issues such as the problems translating court cases.
- MinT test instance provides consistent language names with Wikipedia by using Wikipedia APIs instead of the limited browser localization capabilities.
- Launched the Language Identification service to automatically detect in which language is written a given text. The service supports the detection of 201 languages, and anyone can access the API to use the service or read the model card for more details. Machine Learning team completed the last checks after deploying to LiftWing and evaluating that the service can "easily withstand a high amount of traffic".
- Basic support for rich text translation by supporting transferring of markup to apply styling such as words in bold from the source text into the equivalent ones in the machine translation (which lacks format since translation models operate with plain-text).
- Completed the process to enable MinT for languages with no Wikipedia yet. Translation models in MinT support 25 languages for which there is no Wikipedia. These can be tested in MinT's test instance for speakers of those languages to assess quality, and ensures that translation tools are well-equipped once wikis are created for those languages (as it has been the case with the recent graduation of Fon Wikipedia out of incubator).
- Completed the process to enable MinT for closely-related languages based on Community input. For some languages where machine translation is not available, Wikipedia editors have asked to have access to machine translation in Content Translation using a related language instead of having no support at all. With this enablement translators of Gan (gan) Wikipedia will have machine translation based on the traditional script variant of Chinese as a starting point.
- Analysis of translation activity on 55 languages for which MinT provides machine translation for the first time shows how (a) translations have increased 2X since MinT is available, and (b) deletion rates have not increased. Activity levels for these 55 wikis changed from ~500 translations/month, to 1K+ translations/month after MinT was enabled. For example, a recent peak of 2.15K translations were published in August 2023 when MinT was available for those languages, which is a significant increase from 225 translations in August 2022 when MinT was not available for them.
- Better visibility of translation quality by including a tag in translations where unedited machine translation is close to the limits. This will facilitate analysis about translation quality and limits.
- Created prototypes for upcoming research illustrating 5 concepts on how MinT can be used by Wikipedia readers and supporting the 4 languages we will conduct research in: Hindi, Chattisgarhi, Awadhi, and Korean.
- Improvements for MinT to process more predictably contents with new lines in them.
