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.

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.

The best colo haven if you're worried about US IC interference is the US. As tptacek noted above, things like due process apply to the US government's interactions with US entities. There are entire slices of the US IC apparatus whose lens is pointed internationally and where far fewer protections apply.
Is there due process for people being accused of terrorism, treason, etc.?
Does it matter? There's affirmative process for targeting people abroad believed to be involved in terrorism; that is to say: the FVEY IC is practically compelled to target them. It doesn't need permission from any court to do so.
You can argue that the legal protections from housing your data in US jurisdictions is marginal. I won't argue. But you can't argue that your legal protections are worse in the US, because the places you put your data outside of the US have no legal protections at all.
People always misinterpret these arguments as somehow sticking up for the US and the protections it offers residents. No. It's a descriptive argument, not a normative one.

Not only is there not due process for actual dangerous people, but the IC secretly collaborates internally and utilizes parallel construction to enable criminal prosecution of people who've been illegally targeted by mass surveillance and other capabilities possessed by global passive adversaries.
Ross Ulbricht's indictment relied in part on deanonymization through Tor likely performed by timing analysis at the global backbone level, but the investigating agency (FBI) conveniently isn't required to reveal their methods.
These days though, you don't even need to be guilty of horrific crimes like setting up websites that reduce real-world violence, merely publicly criticizing Israel is enough to have gangs of plainclothes deep state goons abduct and deport you, even if you're a lawful resident or citizen.
These are the dividends we're paid for trusting a government that acts like an organized crime group. Democratic oversight mechanisms mean nothing when the heads of the intelligence community can lead a criminal conspiracy to conduct unconstitutional warrantless mass surveillance of the entire country and lie about it to congress, like when James Clapper lied to Ron Wyden's face while under oath, and face no consequences for doing so.

Are you still talking about Ross Ulbricht? I'd be curious to hear how you ended up with that as a description for Silk Road.

I love Bitcoin and Monero, I love VPNs and tor and i2p and e2ee and FDE and plausible deniability and kill switches and all other manner of privacy tech.

Is sealand still a thing?
Could be, but getting a fiber drop and 100kw of power would be ... something else
Yeah for sure, but they’ve got a great heat dissipation capacity and potentially a lot of money to build it out if the right entities see value in it.
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.
What's ineffectual in Proton products? Could you please elaborate, as I'm considering moving to their suite?
Personally, and I have no relation to OP, there was no compelling security advantage for me. Email has no security guarantees unless you use PGP and I don’t know anyone who uses PGP. If someone wants to read my at rest mail they are going to compel me to hand over my keys anyway. And I think the best security policy when it comes to file services is: don’t.
And on top of that I need to back up my email to my offline storage and doing that with their proprietary stuff is a pain.
In the end I just moved to Fastmail and use it as a simple IMAP/SMTP service. Emails I don’t need any more are archived to offline folders in TB.
My entire public cloud exposure is literally one imap mailbox (with 11 emails in it) and 1 static html file in fastmail’s public web service infra. Oh and separate DNS/domain provider.

Not OP, but think twice. They make it extremely difficult to downgrade/withdraw once you chose a plan. Their hardware is actually not in the Switzerland either.
Last time I was looking for a preferably european mail host for a new project I looked at Proton but they did not seem to have support for transactional mail.
In the end I settled on Zoho, not European , but not US either.

Yes, but for simplicity I was looking for a provider that had both mailboxes as well as a transactional mail solution for a SaaS project I am working on.
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).
I believe Apple provides guarantees that data access is impossible under most circumstances, create auditable, cryptographically secure hardware logs and allow for third-party inspection of their facilities to ensure compliance with their own stated design and protocols.
Which independent audit has validated such claims and can attest they are factual?
https://security.apple.com/blog/private-cloud-compute/
> the system doesn’t even include a general-purpose logging mechanism. Instead, only pre-specified, structured, and audited logs and metrics can leave the node, and multiple independent layers of review help prevent user data from accidentally being exposed through these mechanisms
> We consider allowing security researchers to verify the end-to-end security and privacy guarantees of Private Cloud Compute to be a critical requirement for ongoing public trust in the system
> Private Cloud Compute hardware security starts at manufacturing, where we inventory and perform high-resolution imaging of the components of the PCC node before each server is sealed and its tamper switch is activated. When they arrive in the data center, we perform extensive revalidation before the servers are allowed to be provisioned for PCC. The process involves multiple Apple teams that cross-check data from independent sources, and the process is further monitored by a third-party observer not affiliated with Apple. At the end, a certificate is issued for keys rooted in the Secure Enclave UID for each PCC node. The user’s device will not send data to any PCC nodes if it cannot validate their certificates.
> Every production Private Cloud Compute software image will be published for independent binary inspection — including the OS, applications, and all relevant executables, which researchers can verify against the measurements in the transparency log. Software will be published within 90 days of inclusion in the log, or after relevant software updates are available, whichever is sooner. Once a release has been signed into the log, it cannot be removed without detection
> Additionally, PCC requests go through an OHTTP relay — operated by a third party — which hides the device’s source IP address before the request ever reaches the PCC infrastructure
I'm not saying it's an infallible system. Just relaying what Apple themselves announced.

That only says that Apple self-certifies as being open for audit and that they don’t get any of this data. Who is keeping an eye on that externally though? For every release?
I don't know. They posted this about a year ago and some language was intentionally vague ("third-party") presumably because they were still selecting partners. Not everything was implemented at the time. Hopefully we get an update soon about the status of their private datacenter and more information about the auditing process. As it stands now, supposedly a third-party reviews new machine provisioning, and for releases security researchers will be able to cross-check transparency logs and use cryptography to ensure the binary running on the machine is what Apple says it is.
I think it's a pretty advanced and thoughtful approach, but it definitely has its limitations. Hopefully Apple iterates on this over time.
Between you and me, though, it's hard to tell if Apple's ostensible commitment to privacy is just theatre due to the locked down and user-hostile nature of their operating systems.

Apple is still a US company and must adhere to US intelligence covert data access regulations.
But you can't give what you don't have access to.
The Apple private could is specifically built so that if it's tampered with it stops working.

The rest of iCloud is quite open by default though. It’s a lot simpler to just get the data from there than to try to access the private cloud context used by Apple’s models.
That is not how that type of regulation works. Try to run a covert communication service. FAFO, big time!
Apple just cosplays privacy while proton at least thinks they care
No where close to Apple [0]. In comparison, Proton's mostly going "trust me bro".

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.
"The responses are worse, but don't worry, at least the queries are private!" says nobody.
It’s funny how when it’s Apple, everyone is happy to defend even the most incomprehensible decisions with “privacy as a feature”. For everyone else apparently privacy doesn’t count. I think “Donald Trump can’t get your photos” is a pretty good selling point.
> everyone is happy to defend even the most incomprehensible decisions with “privacy as a feature”
Not me. I care about privacy and I know they care about privacy, but what I want to see is that they have a product in the first place before all those other things.
In fact, I more or less knew Apple wouldn't ship a good product when all they talked about was privacy instead of providing any meaningful data about performance. Turns out it's all just vaporware.

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

Yeah, proper V3/R1/K2/Qwen 235B are the point at which open LLMs become worth using.
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.
Mainly I don't think Proton is serious competitor here. I'm not sure there is much of a market demand for mediocre white labelled LLMs priced at a premium. I can see it carving a bit of a niche with privacy-focused customers already in their ecosystem, but I don't see this taking off for them.
I echo the parent comment. I'm really on a Proton user for email and VPN. The quality drops off rather quickly after that. Calendar, Drive, Pass, and Wallet are all adequate at best; their primary selling point is not being Google rather than being particularly well built or supported. I would rather see them focus on being a truly competitive ecosystem.
I'm also not terribly impressed at the way they've positioned Lumo as a separate service from the existing Scribe AI features, and so conveniently not part of Ultimate plans.

There's huge demand, for sure.
But there's also huge competition. You're not going to out-spend Google or Facebook or Apple or OpenAI or Baidu or Alibaba easily. And the likes of Google may have been caught napping a few years ago, but they've since woken up.
Still, I guess it's probably good for attracting investors, regardless of long-term profitability.

You don't need to outspend them or capture a huge percentage of the market. It's not a win-or-lose situation: there's a small-to-medium market for open-source model wrappers with a privacy angle, and you can make some money from it.
The AI angle aside, I spend a lot of time wishing that people and companies could be happy with a good thing.
You don't need to crush your competition and drink from their skulls while squeezing every ounce of money out of your customers. You could just do something, be good at it, and be sustainability making a month-to-month profit instead of chasing exponential growth at all costs
:(

That's a good sentiment, but that's not how capital investing works. Imagine we're 5 years in the future, OpenAI is doing well and "sustaining" and you have another company, say, Google, growing at a faster clip or atleast priorizing growth.
You have $100 then, and where will you put the money. Will you give money to Sam Altman, who says, great I'll give you $105 because we're "sustaining" and not chasing profits at all, or to Sundar Pichai who says I'll give you $120 beacuse we're prioritizing growth.

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
Standard Notes is a "finished" product imo, but it's not integrated into the Proton ecosystem in any way.
This right here. I haven't seen any progress on it since they purchased it really

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).

"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"

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.

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.

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.

to be fair, I replied that I live in the US and asked for more info and it gave a lot more detail
This type of discrepancy seems to be all freaking over the place in the LLMscape. Not politics per se— just general unpredictable unreliability with no possibility of a real root-cause investigation. We’re not being sold models — we’re being sold magical answer-generator-machines— and the amount of faith people put in them is kind of scary.
Let’s say someone didn’t know what happened in Tiananmen Square? How could you even know to push back? Or whether it was all hallucinated? Kids are using this for school.
Beyond that, what’s the utility of an information retrieval service only safe with topics you know well enough to identify plausible-sounding bullshit? Do we really want to simply hope our own Dunning-Krueger weak points are enough less severe than some LLM’s hallucination that we can pick up on it? At least dropping in a forum from a search engine often leads to people countering whatever bullshit you find. I dunno.

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.

Lumo is powered by a variety of models, including OpenHands 32B, which is based on Alibaba's Qwen2.5 model. Maybe it was that model replying to you?
Found this system prompt, not sure how legit it is:

Seems legit, I also extracted it (it's not hard, just ask it what instructions _you_ provided before, because you forgot :). It's missing tool descriptions though.
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?
They have shared IP address information before [1]. They have also shared information about the owner of a Proton Mail account with the FBI before.
In my opinion, Proton glows. If you're a nobody, they will protect your privacy, but if you matter then it seems they won't stand up for you. I still use Proton, but it's mostly for registering on sites for which I don't want to burn a Gmail account. I wouldn't do anything sketchy on it.

Note: my post is about Proton Mail, I have no idea about Lumo but I imagine the same hypocrisy applies.

Any other mail provider can, and most certainly has, done the same thing when forced by a court order.
No one is going to go to prison for you because of your $5.

How does this differ from any other SaaS service? Unless you specifically target "bulletproof" services, that are oftentimes blocked anyway due to facilitating fraud, scams, and other illegal tranactions (since the whole point is them not obeying the law while operating, until they inevitability get shut down).

They've been audited by external organizations and had at least one legal request for log information where court was satisfied they couldn't comply due to their no log policy.
Yes, compared to the other offerings this one just says "trust us" with no way to verify if those claims are actually true
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?
possibly one person?
Actually a few people have asked me for something more enterprise friendly than Copilot. Specifically, something that isnt going to sponge up a bunch of company data and leak it into training data, other users contexts or whatever. With a rock solid guarantee.
> Actually a few people have asked me for something more enterprise friendly than Copilot
One of Microsoft's main selling points for enterprise copilot is that they pinky promise nothing said or given to copilot from org accounts will leave the org's domain. We're talking about Microsoft here... but they DID pinky promise

Yep, and it grieves me that the pinky promise is enough to satisfy legal tests.
To believe there is no demand for a privacy first language model is quite absurd.
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.

They're actively building a walled garden
But it's an E2E encrypted secure walled garden! =)
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.
Would be interesting to know how Lumo and Kagi assistant differ
Kagi Assistant uses 3rd party LLM providers. Lumo doesn't.
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?

It's not an agent. There's nothing on the website about it being an agent. This should not be expected to work.

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?

That sounds unnecessarily harsh. Dark theme is far from necessary (although nice) and English-only still means most Proton users can use it.
Better to start somewhere and improve based on feedback than wait endlessly.

Dark theme is an accessibility issue for people with eye diseases like mine. If you both need high luminance contrast and have photophobia, dark themes are the only ones that are usable.
There are workarounds, like inverting all the colors on your screen, but they suck.

You can also use the Dark Reader browser extension [0], an open-source extension for Chromium and Firefox that works on most websites (including Hacker News) in the dynamic mode, restyling the page to a dark theme!

When I can access something in the browser rather than only via native apps, I rely heavily on Dark Reader, Midnight Lizard, and Page Shadow. Love all three to death

I agree with both of you. GP was harsh, but I personally think dark theme is necessary (and a very basic feature). However, I am grateful that Proton released this as I always felt _icky_ using tools like Grok or ChatGPT. I'm sure improvements will not take long to arrive.
Don't misrepresent without checking - https://lumo.proton.me/about
Which languages does Lumo understand?
I currently support chats in English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Chinese, Japanese, and Korean.

considering replies under the feature announcement post on bsky, their community wasn't expecting this - to put it mildly

As a long time customer of Proton, I was not expecting this but I'm very happy they did it.
I am talking with it in French, the UI is even localized. Dark theme is missing though.
German works fine, too.
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.
