#apertus — Public Fediverse posts

@vincent @wbpeckham @cxiao I struggle to find any ethical flaws with #Apertus at the moment.

Human marking of abusive content was a nasty response to demands to impose censorship (euphemistically called "guardrails") into #AI .

Thanks to the 50+ contributors helping to launch Public AI Switzerland at the grassroots - a cooperative that embodies open standards, respects user data sovereignty and embodies shared economy principles - aiming to serve the common interest as a trusted public utility. 

Initiated with the support of the international #PublicAI Network, based on the #Apertus model, aligned to many of the same principles that make ActivityPub and the Open Web work for millions of people today.

Moving toward open-weight AI offers both accountability and efficiency

While mega #datacenters dominate, efficiency gains remain elusive. Decentralization may indeed address AI's mounting energy issues and addressing specialized demands in #scientific applications.

Alternative (more) #sustainable #llm: fully open, transparent, locally-deployable, and compliant with data protection and copyrights, as exemplified by #apertus by Swiss institutions

I think the fine tuning, and model specialization here is really what is interesting.

But this should be achievable with open models that are more ethical like #swissai #apertus 1.5

SRG-Chefin #SusanneWille im #NZZS-Interview:

Seit August weist die SRG KI-#Trainingsbots ab, künftig soll ihr #Archiv dem Schweizer #KIModell #Apertus dienen.

Ihr Fazit: „Unser Journalismus ist etwas wert."

Als Vorbild dient Frankreichs „Must-be-found"-Regel für öffentlich-rechtliche Inhalte.

Und eine Mahnung mit Verweis auf den Club of Rome: Die grösste Gefahr sei nicht Krieg, sondern die Unfähigkeit, #Fakten von #Fiktion zu unterscheiden.

@geerlingguy I am using a #pi4 with #Mistral 3B as my document classifier. I would prefer #Apertus but while 8B outperforms Mistral 3B, its too heavy for the Pi4 and the 1.5B/4B variations quality is not sufficient https://codeberg.org/lsmith/nextcloud-classification/src/branch/experiment/eval-force-json/docs/apertus-mini-evaluation.md

So I am intrigued by testing out a #pi5 16GB with Apertus 8B. FTR Apertus v1.5 8B isn't yet ready for a Pi5 deployment https://mastodon.green/@lsmith/117054219745284915 //cc @loleg

Here's a capture from the one-shot prompt using #OpenCode to "Develop a small animation in a single HTML file with a vanilla JavaScript block. It should create an animated Matrix-like effect on the screen." #Apertus

Quick vibe check of #Apertus 1.5 70B running on the #OpenHands community-maintained TUI,. Suggestions of other tools, benchmarks and policies welcome

Anastasia Stasenko hits the nail on the head, addressing fairness and equity issues with the economic models of AI projects, not least the leadership opportunities for those implementing #Apertus or her own #Pleias LLM #POSAIS26

Open AI model #Apertus performs rather well in the (non-scientific) "city guide" benchmark:

"The question is not "sovereign AI or quality" but "how much quality gap are you willing to accept for full sovereignty?" And that gap is closing."

Response of Apertus 1.1 4B, on a RAG that includes documentation of the #Apertus project, and the recently published preliminary report from the UN Scientific Panel on AI:

~ Actionable Recommendation ~

Encourage the Swiss AI Initiative to develop a National Action Plan that:

A. Requires pilot projects with clear, measurable transparency targets linked to local authorities and public engagement.

B. Mandates the development of implementation guidelines with case studies that assess compliance, including provisions for data quality and global interoperability.

C. Establishes an annual reporting mechanism, not just to Swiss authorities but to the public and local governments outside of Switzerland.

After such a plan is implemented, the Swiss AI Initiative should conduct an inter-cantonal review assessing alignment across all cantons.

Civil Society Organizations engaged in research, community projects, or who experience AI adoption should be brought into the process to feedback directly on:

- The feasibility of requirements (e.g., data volume, technical complexity) in their respective contexts.
- The balance between compliance and innovation (potential for slowing the pace of adoption).

The Swiss AI Charter provides a solid theoretical foundation, but its operational applicability requires nuanced implementation that takes into account varying national legal and socio-cultural frameworks.

Actioning this will help the initiative build pragmatic frameworks that balance universality with adaptability, avoiding overregulation in some contexts while ensuring core principles are not eroded.

Thanks to @huggingface for hosting the #Apertus models, providing unrelenting support to thousands of research teams. Follow my profile at https://huggingface.co/posts/loleg/638385270166815

I tried out #Apertus at https://chat.publicai.co/ today and like the project. It was confident but not great at converting hex to decimal but it gave me Python code and a online website to do the same calculation and simply had severe trouble believing they'd give a different answer. Would use again.

I also learned that a training data cutoff date of 2024 allowed it to link to an USIP Primer on a hot topic that my browser instantly tagged as a security hazard. (No, don't go click on that link out of curiosity. Read the Wikipedia article on USIP instead. That stuff reads like a contemporary crypto standardization mailing list.) That was enough internet for one day thank you, I will go back to reading my holiday paper newspapers now. :D

A slide from a Builders Summit* presentation a few months ago that I keep coming back to in my work on #Apertus - where do you see The Feedback Loop in #opensource?

"Für #Giotto wäre #Apertus die perfekte Grundlage. Erstens wäre das Modell dadurch vollständig in Europa entstanden – und damit ein grosses Stück souveräner, als es Giotto allein ist. Zweitens ist Podestà sehr daran gelegen, mit seiner KI die Vorgaben der #EU zu befolgen."

Adieu Chat-GPT? Schweizer KI G...

@loleg re-ran the 4B on the newer mradermacher GGUF (built w/ post-Oct-2025 llama.cpp):

good news, the "never terminates" bug is fixed, done_reason: stop now.

two catchea

1) unconstrained it emits prose, not JSON (0% parseable), so format:json stays mandatory for content, not just stopping;
2) f16 scores 26% = same as Q4, so precision isn't the gap either.

so don't think "few-shot could help". ~26% ceiling looks real. hoping for #apertus 1.5 !

Thanks to @lsmith (our photographer and edge computing champ) and Marzili campus for helping to host a big chunk of the #Apertus team in Bern today

@lsmith warm wishes from me and the rest of the #Apertus team, watching the game after a long all-hands workshop to plan the next steps. Hopp Schweiz! 🇨🇭

Do you know how much work it is to keep track of the CO² footprint of your computer? Imagine that of a whole institution, or a national research program.

Today I had the chance to debate this with an Advisory Working Group of https://sustainableit.org and share a high level strategy of the EPFL, along with the challenges of running a more sustainable data center at CSCS and RCP.

We are only at the beginning of the journey with #Apertus but the waypoints are clear, and the climate too hot to ignore a minute longer 🔥

Congratulations to each of the 102 authors of the #Apertus v1 report, officially published today ahead of the presentation at #ACL2026NLP in July. Follow @aclmeeting for updates https://aclanthology.org/2026.acl-long.2172/

@loleg well it depends on if #Apertus 1.5 small is a bit smaller. 8B takes over an hour per prompt on my #pi4 :(

🇨🇭 #Apertus is Switzerland’s first large-scale, open, multilingual language model. Developed by researchers at ETH Zurich, EPFL, and the Swiss National Supercomputing Centre, it represents a new approach: built by public institutions, designed for the public good. #sovereignty #Switzerland #AI

Apertus – Open Foundation Model for Sovereign AI

#HackerNews #Apertus #SovereignAI #OpenSource #AIModel #AIResearch #TechInnovation

Switzerland’s parliament has approved a law allowing voters to sign petitions and referendums digitally. The Foundation for Direct Democracy and the @digiges underline that the digital system must be secure, transparent, and accessible, with #opensource code and decentralized data handling.

They also argue that digital signatures can make direct #democracy more inclusive and safer, especially for those who cannot sign on paper. The trial must be implemented nationwide and in line with the law’s principles.

The responsibility now falls to the Federal Chancellery to ensure the #ecollecting trial meets these standards, starting as soon as possible to benefit those with #disability
