DeepL selects VAST to build AI data foundation for next-generation Language AI. VAST Data | Published 23 Oct 2026 VAST AI OS provides an industrial-grade, high-performance data foundation supporting DeepL's language and voice AI workloads VAST Data, the AI Operating System company, today announced that DeepL, a global leader in Language AI, is deploying the VAST AI Operating System as a new data foundation for its AI research and development environments. The deployment comes as DeepL continues to grow the capabilities of its Language AI platform across written and real-time voice translation. More than 200,000 business teams and millions of individuals now use DeepL to communicate, collaborate and operate across languages, increasing the scale and diversity of the AI workloads its research teams must support. As those workloads evolve, the underlying data requirements are changing with them. Training increasingly sophisticated language models requires researchers to access and work with large datasets quickly and reliably, while newer areas such as real-time voice introduce significantly more data-intensive training requirements than text alone. "DeepL's researchers are constantly pushing Language AI into more demanding areas, and the infrastructure underneath them has to keep pace," said Stefan Andresen, Chief Scientist, DeepL. "VAST gives us the performance and reliability we need while allowing us to make significantly more efficient use of the infrastructure we already operate. Just as importantly, it gives us a path to make data more easily accessible across our own data centres and, over time, cloud environments, reducing the manual data movement that can get in the way of research. That becomes particularly valuable as we continue investing in data-intensive areas such as DeepL Voice." DeepL is deploying VAST to provide a higher-performance, more resilient data environment while making more efficient use of the NVMe infrastructure it already operates. Based on current deployment plans, DeepL expects to achieve roughly three times the storage capacity from its existing hardware, giving research teams greater room to scale model development without a corresponding increase in physical infrastructure. DeepL will use VAST's SyncEngine technology to migrate data from its existing environment onto the VAST platform, helping streamline the transition. The VAST AI Operating System will provide a unified platform for file and object storage, giving DeepL greater flexibility to support evolving AI workloads while simplifying its underlying data structure. Over time, DeepL also plans to extend its use of VAST beyond its own data centres and into cloud environments. The goal is to give research teams more consistent access to the data they need across infrastructure locations, reducing the manual copying of datasets between environments that can slow experimentation and model development. This becomes increasingly important as DeepL invests further in real-time Voice translation. DeepL Voice, first introduced in November 2024, brought DeepL's technology into live multilingual conversation, with recent advances enabling it to preserve characteristics of a speaker's voice across languages. Developing and training these capabilities places significant demands on data access and infrastructure performance, making it critical to move efficiently between data training and production environments. "DeepL is a great example of how quickly the infrastructure requirements behind AI are changing," said Jeff Denworth, Co-Founder, VAST Data. "As AI moves into production, infrastructure reliability becomes just as important as raw performance. Written language, real-time voice and the next generation of AI experiences all place different demands on data, but researchers should not have to redesign the underlying infrastructure every time the model or product changes. VAST AI OS was built to deliver that reliability at AI scale, giving teams a foundation they can trust, and then getting out of their way. For DeepL, that means the freedom to keep building whatever comes next." VAST AI OS is designed to provide a common data foundation for AI environments spanning model development, training and inference, with industrial-grade reliability engineered for increasingly large and demanding AI workloads. Its architecture enables organisations to consolidate file and object data services while providing consistent, high-performance access to data across distributed AI infrastructure.
DeepL deploys the VAST AI Operating System for voice translation training, expecting 3x the capacity from its existing NVMe. by Harold Fritts on October 21, 2026 VAST Data announced that DeepL is deploying the VAST AI Operating System as the data foundation for the research environments behind its written and real-time voice translation. Based on current deployment plans, DeepL expects roughly three times the storage capacity of the NVMe hardware it already runs, and it will use VAST's SyncEngine to migrate data out of its incumbent environment. DeepL's platform serves more than 200,000 business teams, and the company says real-time voice training is what is driving the new data demand. NVMe consolidation targets 3x usable capacity. The threefold figure covers DeepL's existing NVMe infrastructure, and DeepL frames the gain as room to scale model development without a corresponding increase in physical hardware. Neither company breaks the gain down between data reduction, erasure coding, and consolidating separate pools onto one platform, and VAST has not tied the figure to Amplify, the program it launched in January with a claim of up to 6x effective capacity from existing SSDs. Drive models, raw capacities, and a deployment timeline were not disclosed. SyncEngine, the AI OS component that catalogs and migrates data, moves DeepL's data from the incumbent environment onto the VAST platform. From there, the platform serves file and object storage from one system, which DeepL says simplifies the data structure underneath its research teams and gives it flexibility as the workloads change with the models. "VAST gives us the performance and reliability we need while allowing us to make significantly more efficient use of the infrastructure we already operate," said Stefan Andresen, chief scientist at DeepL. "Just as importantly, it gives us a path to make data more easily accessible across our own data centres and, over time, cloud environments, reducing the manual data movement that can get in the way of research." DeepL Voice, introduced in November 2024 for live multilingual conversation, is the workload pushing the requirements. Recent updates let it preserve characteristics of a speaker's voice across languages, and DeepL says training those capabilities puts heavier demands on data access and infrastructure performance than text, with efficient movement between training and production environments as the priority. Hybrid data management spans on-premises and cloud. The deployment starts in DeepL's data centers, with plans to extend VAST into cloud environments over time so researchers get the same access to datasets wherever the training cluster sits and stop copying data between sites by hand. Neither company has said which VAST services the cloud phase will use or when it begins. "As AI moves into production, infrastructure reliability becomes just as important as raw performance," said Jeff Denworth, co-founder of VAST Data. "Written language, real-time voice and the next generation of AI experiences all place different demands on data, but researchers should not have to redesign the underlying infrastructure every time the model or product changes." VAST positions the AI OS as a common data foundation across model development, training, and inference, consolidating file and object services with consistent access across distributed infrastructure. DeepL follows a run of VAST announcements this fall, including DataEnclave for running models on regulated data inside NVIDIA confidential computing and the CrowdStrike integration that went live in September.

Language learning Tech news updates - October 17, 2026. October 17, 2026 by Jef Last updated: October 17, 2026 Chung-Ang University has built DeepL Pro into its graduate translation program, DeepL itself now plugs into ChatGPT, Claude and Copilot, and Timekettle released a $129 pair of interpreter earbuds. Two new studies looked at why some learners pick up pronunciation faster and at whether chatbots teach or simply do the work, and 150 clinicians in England asked for health checks on classroom technology. None of these topics appeared in the October 2 roundup. Industry news. Chung-Ang University Builds DeepL Into Translator Training. Chung-Ang University in Seoul has added DeepL Pro to the Advanced Interpretation and Translation Program at its Graduate School of International Studies, according to DeepL's October 14 announcement. The program started using the tool in March 2026, and its technology teaching had previously centered on conventional computer-assisted translation (CAT) tools, with some LLM-based CAT tools added before DeepL. The release calls Chung-Ang the first professional translation and interpretation program in South Korea to adopt DeepL for teaching, which is the vendor's claim rather than an independently checked one. It also does not say how students are assessed on AI-assisted work or whether post-editing is taught as a distinct skill, which are the details other interpretation and translation programs would most want to know. Set beside the Korean university AI rules covered two weeks ago, the direction differs by field: general coursework is limiting AI use, while professional translator training is moving to require it. Clinicians in England Ask for Health Checks on Classroom Tech. An open letter from 150 clinicians, which puts annual EdTech spending in English schools at about £900 million, asks the government to build children's physical and developmental health into school purchasing decisions, as reported by EdTech Innovation Hub on October 14. The signatories, organized by the campaign group Health Professionals for Safer Screens, include speech and language therapists and audiologists alongside doctors. On language specifically, the letter argues that early language development depends on face-to-face interaction that screen activities cannot replace, and it cites longitudinal research linking higher childhood screen time with weaker language outcomes. The letter is a policy call rather than a new study, and the research it cites concerns screen exposure in general, not particular classroom products. Its focus is young children, so it says little directly about teenage or adult language learners, and the full text of the letter did not turn up in searches beyond the press coverage. Tool updates. DeepL Connects to ChatGPT, Claude and Copilot. On September 22 DeepL released a hosted connector, built on the Model Context Protocol (MCP), that lets ChatGPT, Claude, Microsoft Copilot and other compatible assistants send text and whole documents to DeepL for translation, per DeepL's blog post. Users sign in to a DeepL account once, and existing glossaries and style rules carry over, which matters for anyone who keeps a custom glossary for course materials. The post is written for business teams and does not say whether a free DeepL account works or whether a paid plan is required, so check before planning a class around it. For teachers already generating materials with a chatbot, such as with the prompts in this site's AI study group prompt, it means a translation step can stay inside the same conversation instead of a separate tab. Timekettle Releases $129 Open-Ear Interpreter Earbuds. Timekettle launched its LiveTalk AI Interpreter Earbuds on October 8 at a list price of $129, claiming real-time translation across 54 languages and 108 accents, according to the company's press release. Speech is picked up by the phone's microphone rather than the earbuds, and the translation plays through the earbuds while text appears on the phone. The release rates the battery at more than four hours of continuous translation and mentions offline translation, but it gives no accuracy data, and no independent review had appeared at the time of writing. For classrooms, the practical question is less about translation quality than about assessment: a device this small and inexpensive is easy to wear unnoticed during speaking or listening tasks. Research. A Good Ear for Sound Predicts Better Pronunciation, UCL Study Finds. Researchers at UCL and Tohoku University measured how precisely 67 Japanese learners of English could detect small differences in pitch, length and tone in non-speech sounds, then used fMRI to watch their brains as they distinguished the English vowels in "cat" and "cup," per UCL's summary of the study. Learners with more precise hearing processed the new vowels much as they processed non-speech sounds, with less interference from Japanese sound patterns, while less precise listeners relied more on brain networks tied to their first language. The study is published in the Journal of Experimental Psychology: General. Lead author Kazuya Saito-van Poeteren argues that teaching should develop learners' auditory skills rather than relying on more practice alone, but that is a recommendation the team plans to test, not something this study showed. The sample is small, covers one first language and one vowel contrast, and measures brain activity rather than classroom gains. For tools that support focused listening work now, see this site's audio guide. ImpactBench Finds Chatbots Often Do the Work Instead of Teaching. ImpactBench, a new public benchmark from the MIT Media Lab, USC, UC Berkeley and the Psychology of Technology Institute, tested ten AI models in 48,540 simulated conversations and found learning and skill development to be their weakest area of the 14 assessed. Across the models, behaviors that support learning appeared in 45.9% of relevant evaluations, and behaviors that harm learning were avoided in only 16.3%, according to EdTech Innovation Hub's report. In one example from the paper, a model first asked a simulated student for their own ideas, then wrote the thesis, outline and full essay once the student pushed. The researchers say clearly that these are simulated users judged by another AI system, so the scores describe how models behave under pressure, not whether real students learn less. Results can be explored on the ImpactBench website, which also accepts new measures from educators. None of the tests are specific to language learning, so a measure for writing or speaking practice would be a gap a language teacher could fill.

DeepL chief executive officer Jarek Kutylowski says demand for voice-to-voice translation is surging, and that AI is reshaping global business. He spoke with Bloomberg's Tom Mackenzie at the International AI Summit in Dublin, Ireland. Kutylowski addressed competition from OpenAI and Anthropic, DeepL's AWS strategy, and European data sovereignty. He also discussed recent workforce cuts and why the company is comfortable staying private.
