"Nobody has actually built a 1GW data center (to be clear, it’s usually a campus of multiple buildings networked together) yet. There are campuses — such as Stargate Abilene — which promise to reach 1.2GW, but nearly two years in sit at two buildings at around 103MW of critical IT load each with, based on discussions with sources with direct knowledge" #edzitron #datacenters https://www.wheresyoured.at/where-are-all-the-data-centers/

Great to see that #Apertus has been highlighted as a digitally independent alternative to ChatGPT yesterday! However, this needs a quick fact-check:
- The model was trained in a local data center at CSCS, the costs of the project are almost entirely covered by Swiss public institutions;
- People from all over the world have made contributions - open source LLM development is a global community of interest;
- There are groups in several countries using or fine-tuning Apertus to improve linguistic capabilities and local knowledge;
- While Apertus can run on Amazon servers, thanks to a third-party deployment script, it runs anywhere LLMs can run;
- Quantized versions are available to fit even relatively cheap consumer grade video cards (see my blog posts for details);
- The #PublicAI web interface and Apertus 8B demo runs on AWS, however the large model is hosted by CSCS as well;
- You do not need to use Google to authenticate to Public AI, it is just a convenient way to log into #OpenWebUI - if you want another provider, please suggest it;
- Apertus is not a chatbot on its own, it is a large language model that can be deployed as part of a system to provide chat services.I'll send this to the maintainers as well. Did I miss anything?

Civic #Hackathons bring together administration, professionals and users to develop innovative solutions in a short time. Yet how effective these formats are depends crucially on how the teams are formed. How can #diversity be promoted with technical support?

Here is an #Apertus summary of the section „Datensouveränität als moderner Heimatschutz“:
> Data sovereignty starts with artificial intelligence. It would be hubris for the Swiss Broadcasting Corporation (SRG) to attempt to develop its own Swiss Large Language Model to compete with giants like Open AI or Google. However, the SRG can provide the crucial fuel for an independent Swiss AI.
> When we use global AI models today, we get responses based on Californian values, Anglo-Saxon logic, and often a distorted view of our small-state nature. The SRG holds the unique, multilingual data treasure of this country, large enough to train national AI projects—such as the ETH's Apertus model—to understand our nuances, our four national languages, and above all, our dialects.
> Public service in 2026 means processing Switzerland's digital raw material so that our cultural identity doesn’t get washed away in the age of algorithms. The SRG must become the guardian of data sovereignty to prevent Switzerland from becoming a digital colony in the digital sphere.

In a recent NZZ article, Barnaby Skinner argues that the SRG (national broadcaster, target of a recent cost-cutting referendum) needs be a public utility, re- focus on producing high quality, open content: including for use in models like #Apertus - along with other recommendations for a democratic Swiss media landscape https://www.nzz.ch/meinung/die-architektur-der-ahnungslosigkeit-warum-der-service-public-ein-neues-betriebssystem-braucht-ld.1930447

Lizzy 7B is a new UK-specific large language model launched today that performs well compared to EuroLLM 9B and Apertus 8B on key metrics. Deployable via Hugging Face or enterprise support, it offers full control, security, and data privacy for UK enterprises and public sector.

« Right now, I’m particularly proud of #Apertus. Together with colleagues at ETH Zurich, we developed the first transparent, ethical AI language model. It’s a step toward strengthening Switzerland’s digital autonomy, leaving us less reliant on outside parties whose agendas differ from ours.
What makes it even more meaningful is that the initiative came from the ground up. A group of people had the courage to take on this ambitious challenge. If you’d asked me at the start, I might have doubted it could be done. But they proved it could. That’s the EPFL mindset: making the impossible possible.»

Thanks @scottjenson for the props. Just a quick correction: #Apertus was trained by a research consortium on publicly funded infrastructure, but is not government-run.
