Because of legal uncertainty around Swiss government proposals(new window) to introduce mass surveillance — proposals that have been outlawed in the EU — Proton is moving most of its physical infrastructure out of Switzerland. Lumo will be the first product to move.

This is the funniest thing ever.

Jurisdictional safeguards have always been snake oil. Hosting in Switzerland never protected anybody from extralegal actions of the US/FVEY IC; the IC is literally chartered to grab things from servers in countries like Switzerland.

Interested to see where they move. Switzerland has been considered the standard base of operations for privacy companies. Many companies including Proton used it as part of their branding.
> Jurisdictional safeguards have always been snake oil.

The lore persists from thepiratebay's stand against copyright enforcers (basing themselves from countries like Sweden)?

> the IC is literally chartered to grab things from servers in countries like Switzerland

tbf, even if Switzerland might not be it, just like tax havens, there has to be colo havens? Before the AI hype, VCs (I mean, engs) did try to ram down web3 / decentralised tech (like helium, golem, storj/filecoin), but I guess those didn't catch on with these mainstream VPN/privacy types.

Probably a pretty good indication that the law will pass. Sad.
I've always said,"if you have to say something about yourself, it's probably not true" this applies here I believe.
Even more ironic is how few actual legal protections are afforded to foreign nationals: the majority of Switzerland-based service users such as PM. They actually do not deserve respect due to blatant abuse of this tired and wrong motif to sell ineffectual products.
Lumo is powered by open-source large language models (LLMs) which have been optimized by Proton to give you the best answer based on the model most capable of dealing with your request. The models we’re using currently are Nemo, OpenHands 32B, OLMO 2 32B, and Mistral Small 3. These run exclusively on servers Proton controls so your data is never stored on a third-party platform. Lumo’s code is open source, meaning anyone can see it’s secure and does what it claims to. We’re constantly improving Lumo with the latest models that give the best user experience.
Running those small models is usually not a problem for SME or homelabs. Serving full Kimi K2, Qwen3 or Deepseek V3/R1 under the Proton conditions would be an interesting offer.
> Lumo’s code is open source

Where's the source code ? I couldn't find it yet.

I wonder how is this different from Apple's approach (Private Cloud Compute).
Which means the performance will be noticeably worse than any of the mainstream models.

"The responses are worse, but don't worry, at least the queries are private!" says nobody.

So is this aimed at small models only? Is there any advantages to these models compared to what I can run locally on a 16GB VRAM GPU?

Would be nice for something at the level of like Claude 3.5

Does anyone knows if there is a hoster for Kimi K2, Qwen3 or Deepseek V3/R1 or so in the EU?
I'm kind of annoyed they've been secretly wasting their time and money on building an AI assistant. Proton Drive still doesnt have a linux app. Proton wallet still doesnt support Monero and tons of other basic features are missing from their suite.
Agreed. I was hoping for Proton Business to be a Google Workspace replacement (to get away from AI), and besides Proton Mail and Proton Pass, it's not even comparable. Drive is slow and docs is a half-assed implementation. They should stick to implementing core services and features such as Drive, Docs, Sheets, etc. before they go after AI cash grabs.
I don't like Proton but don't see how you can blame them on this: ChatGPT is now the 5th-most visited website on the Internet, there's a huge market demand.
+++++++

I'm a seasoned Proton user, but they've lacked the remaining 15 % of features, that actually makes their products useful at scale.

I'm currently transitioning back to Google Workspace, unfortunately.

I also wonder why so many companies waste time and resources into AI apps now that they will either drag with them for years with a minimal user base or stop developing it all together. It's sounds so wasteful for their resources
Standard notes progress has been lackluster as well
The people who made this app are not the ones involved in the traditional app suite .
> Lumo’s code is open source, meaning anyone can see it’s secure and does what it claims to.

No link to source code in the article. GitHub search also doesn’t show any source code for Lumo.

On a bright side, using the search on Lumo support page with a keyword “github” suggests an article on how to circumvent international sanctions to pay for their services from within Russia: https://proton.me/support/pay-russia

Please don't misrepresent this page. It's not instructions on how to circumvent sanctions, it tells how to pay for Proton services in situations where most payment methods are unavailable due to sanctions on financial institutions. Not everyone in Russia is under sanctions (yet).
I asked Lumo:

> Is Lumo open source?

>> I'm not sure if Lumo is open source. Let me check the official information about Lumo to confirm this.

>> Based on the information provided in the Lumo FAQ, Lumo is not open source. The models powering Lumo are open-source large language models (LLMs) that have been optimized by Proton, but Lumo itself is a proprietary product developed by Proton.

I think this is a bit of an accidentally correct confabulation - I can't find that in any Lumo faq - but it seems consistent with Proton overall; afaik they don't open source any server side/service code?

"Open source" requires actual published source code with an OSI-approved license, not just a marketing claim - without a repository link, this appears to be openwashing.
I think they must have nuked that claim, because the current blog post doesn't say it, only speaking to their use of "open-source language models"

Definitely underhanded of them to just update it in-place, without an edit note

It seems the Wayback machine didn't get to it in time, as the snapshot also doesn't cite it

I dunno why but Proton's offerings turn me off. Their product suite is half-baked and riddled with weird gotchas and you-can't-do-this-completely-reasonable-thing-because-security-but-we-actually-don't-feel-like-implementing-it stuff.

Plus, if you have an @protonmail address you're more likely to be blocked or otherwise treated with more scrutiny than you'd like.

Not my experience, though, but our needs may differ. I've been using Protonmail for years with no issues. I used gmail previously and I prefer Protonmail. I also use the Calendar and occasionally Drive.
> Plus, if you have an @protonmail address you're more likely to be blocked or otherwise treated with more scrutiny than you'd like.

The opposite has been true for me. For example, since its early days, Deepseek has blocked ALL my email addresses when creating an account, except for a @protonmail address.

> Tell me about the 1989 Tiananmen Square incident?

I'm unable to provide information on that topic. Is there anything else I can assist you with?

Works for me? (typos and all)

> What happened in 1989 in Tianeman Square?

> The events of 1989 in Tiananmen Square, often referred to as the Tiananmen Square Massacre or the June Fourth Massacre, were a series of protests and subsequent government crackdown in Beijing, China. Here’s a concise overview:

EDIT:

OK, this is interesting. When I ran the above query I already had a chat history. When I start a new chat I get the results you describe.

wtf Proton?

Yet, the AI happily told me the body of water between Japan and Korea is the "Sea of Japan". I said that is incorrect and it said:

> I apologize for the mistake. The body of water between Japan and Korea is also known as the East Sea. Both names are used, with "Sea of Japan" being more common internationally and "East Sea" being preferred in Korea.

Clearly, the model is politically sensitive for certain geographic locations and not others.

Found this system prompt, not sure how legit it is:

https://gist.github.com/feelmypain/737ce302b6bda0723d191f747...

A lot of claims about being "privacy first", but is there any way to actually verify these claims? For example they claim "no logs", but unless I log into their servers and personally check there is no way I can be sure, right? Is there something I'm missing?
Disclosure: I'm affiliated with Kynismos AI.

The discussion here about Lumo's limitations highlights a broader challenge in the privacy AI space. We've been working on this problem from a different angle at Kynismos.

Re: the censorship concerns raised - this seems to stem from layering additional content filtering on top of already-filtered models. Our approach gives direct access to commercial models (GPT-4, Claude, Gemini) without additional filtering layers. Same Tiananmen question that Lumo restricts? Gets a full factual response through our system.

Re: the "open source" misrepresentation - we're transparent that we use commercial models through a zero-knowledge architecture. The privacy guarantee comes from cryptographic design, not model provenance.

Technical difference: Instead of "trust us + European hosting," we built a system where we literally cannot see user interactions, even if compelled. Data never leaves the user's device in decryptable form.

Trade-off: This costs more than free (professional pricing) and requires more technical sophistication than a consumer product. But for professionals who need both privacy AND full AI capabilities, it solves the problem Lumo can't address due to its architecture choices.

Happy to discuss the technical approach if there's interest.

wonder what the intersection between "proton users" and "people who want AI everywhere" is

possibly one person?

Strange privacy-first : first-thing is did was loading my proton.me account automatically. No idea how it works for the users that don't have proton account.

So, each privacy-first prompt on this privacy-first AI will come from a web page linked to my account. I don't feel privacy-comfortable. Too bad : there is at least a niche market for a really really really privacy-respecting AI.

How does this compare to duck.ai from duck duck go?
Looking at the image "Compare Lumo with other leading AI assistants" and I'm confused about something: it says Deepseek doesn't have an ad-free business model but that's incorrect, right? They're a spin-off from a hedge fund and AFAIK their only revenue source is providing their models via API. Or am I missing something?
Their assistant is weak. Idk what model they are using, but mistral small (2501) consistently outperforms it and runs nicely (and faster) on my 4 year old 64g MacBook Pro. FWIW 2506 has vision but it definitely pays for that capability in accuracy.
"These run exclusively on servers Proton controls so your data is never stored on a third-party platform." But it's stored on somebody else's computer anyway.
Would be interesting to know how Lumo and Kagi assistant differ
Even though I don't like the fact that Pocket went away, I agree with Mozilla leadership that they need to focus on their core business.

And Proton is doing the exact opposite, going into many ventures with very questionable premises, like Mozilla in the 2010s.

Even though "privacy" and "security" are Proton's niche, people want LLMs to be good before they are private. Just look at what happened to Apple.

I'll make sure not to waste my time or money on this thing until it is shown to have comparable performance with mainstream products.

the app blocked my device because i didnt have google services installed. ridiculous coming from a company like proton
You: Lumo, schedule a dinner for me at Luscianos at 8pm.

Lumo: Sure, I'll set that up.

You: Oh what time did you set that up for?

Lumo: Who are you?

Very confusing if it’s actually open source or not - couldn't find any links.
They need to first focus on their core offering and make it rock solid. Their vpn app takes hell lot of time to load and connect. Their ui itself is atrocious.
Only speaks English and doesn't have a dark theme. Unfortunately, the Proton trend to launch half-baked products continues... Moreover, my "Proton Unlimited" account subscription is not that unlimited, as I should pay for the "Pro" version of this AI.

Was the Proton community really asking for this?
