Introducing Lumo, the AI where every conversation is confidential | Proton

It would be much better if they included Lumo Plus in Unlimited and above subscriptions. If I buy it for whole family, that will break my wallet and descriptions are not clear about the benefits of Plus subscription.

They should have made something similar to Google One AI packages. With Gemini you can share your 2 TB storage, Google One benefits plus Gemini Advanced with all of your family members. That saves a lot of money.

These models that Proton are using for their assistant generally are not competitive with open source SOTA models, at least performance-wise, and potentially cost-wise. Deepseek R1 0528 easily beats Mistral Small 3 in benchmarks, and I do not think I have to cite any sources for this; R1 has over 600 billion parameters and Mistral Small around 24 billion.

Cost-wise, paying ten dollars per month to send unlimited prompts to Mistral Small 3 seems like a waste of money; there is no real need to subscribe to Lumo when you can pay as much or as little as you want and need on an API platform, such as NanoGPT. For reference, Deepseek R1 0528’s Prompts per $1 is 3413 — at least according to NanoGPT’s pricing page (NanoGPT). Of course, Mistral Small 3 may be cheaper by 4x by API, but again, $10 per month to Proton seems excessive for non-SOTA models.

I suspect the only real advantage over API platforms and other websites like ChatGPT or Claude is that Lumo has a complete integration with the Proton suite. If you do not use Proton already and do not intend to do so, Lumo likely is not for you. My two cents

Edit: actually, Lumo does have privacy in the bag; however, if you do seek privacy, I would think that you would choose local hardware

Boy, look at those prices. Wow.

I am so so glad I still have AND ESPECIALLY that Proton lets us keep my Proton Unlimited plan of $111 USD every 2 years/24 months or $55 USD/year.

Yeah, they didn’t even let me keep me current price and asked me to pay full price on renewal. My solution was to cancel my sub. Apart from other issues, that was the major deal breaker for me.

It was happenstance that I bought in before the big rebranding about 5 years ago. Just 2 months before. So, I got lucky really..

I’m not sure why. Also not sure when you bought in and what you were paying. But yeah, I’m very lucky to have the OG Unlimited price still with all that Proton currently offers with the exception of Lumo Plus.

you know what’s worse honestly, they’re not charging me 9.99 a month for every lumo plus subscription like shown in yours, they charge 12.99, seems people are getting different prices (in usd even), crazy, it’s cheaper than Maple, sure but god damn.

I changed mine to CAD (since I am in Canada) and it changed the price for me. Perhaps change the currency and see what it shows or if it changes.

Paying a premium for a private version of Mistral Small 3 isn’t worth it at that price point. Although many privacy-conscious users may refuse to use an LLM in the first place, those that would are technical enough to self-host or willing to compromise by using a ChatGPT/LLaMA Wrapper like Duck.ai (for free!).

At that point, local offline downloaded LLM via Msty, Jan, Ollama, LM Studio, GPT4 ALl etc. is probably a better option.

I still say, if you are not sharing any PII, NanoGPT is fantastic for all that it offers and how being a front end for all premium AI models in the most private and even anonymous way possible.

I see there is a Lumo app on the Google Play Store and Apple Store, but is the apk (or GitHub repository?) for this app already publicly available? I use Obtainium, so I’d like to stay away from the play store if possible.

They just released it today. I’m sure that will come soon enough.

You can use the PWA too.

I just wanted Proton bridge to extend its functionality to include CardDAV and CalDAV… and add this…

smh

I don’t really need Proton Wallet or this AI non-sense. I can spin my own non-sense with my GPU. I understand its not as good as the full model but I didnt really need the full strength when a gaming GPU generated AI is good enough.

I feel like Proton is going with an unsustainable infinite growth mindset that seeks more users by adding new services rather than improving services and infrastructure of what they have right now.

This might be why they are acquiring other companies and starting new services such as this AI slop thing. I would appreciatete it more if Proton would not engage and join the increase in usage/demand of power of the world.

That would be nice indeed.

Not all AI is nonsense. C’mon.. you can’t discount all of AI like that because there are legitimate useful use case for it. The way big tech is doing is terrible indeed, I agree with that and al that Ed Zitron talks about but that is not to say it doesn’t have a use case.

Again, not all AI product or tool is to be seen as AI slop. Starting today, they have solved some of the biggest concerns with generative AI in that the made a AI tool that we can use privately and securely. NanoGPT notwithstanding, this along with offline LLM set ups is the best we have.

Trust me, I am tired of everyone shoving AI into absolutely everything. I hate it as much as the next guy but when an entity tries to do it better and solves one of the major concerns and issues discerning folks like us have, it should be recognized for that and evaluated with objectivity in mind.

Now, I do agree that they could have improved their exiting suite of tools more. For example, they could or should have released Sheets already if not much earlier this year at the latest but they did not. So their Docs/Drive products do feel half assed. I get it. But they have also made Proton Pass absolutely one of if not the best password & credential management app that also offers email aliasing. So, they are indeed improving.

Look, I don’t want anyone to read my comments as one who is shilling for Proton unnecessarily. And that’s why I am also sharing examples of why I feel and say what I am saying.

The way you have written it feels like you’re discounting Proton’s progress without much consideration (as you have not listed any specific grievances you may have).

AI is the product of the decade now. This was only a matter of time. An argument could indeed be made that it was the wrong time to do so perhaps.

I can see people are as confused as me about pricing, but this part was not making it better.


Got excited for this part.


And then I got this.

Lumo still working out the kinks i see…

I went to the store and it was still doing this when I came back lol

Models usually don’t reliably know their knowledge cutoff date nor even know what model they are in many cases (unless they are told what it is in their system prompt). The October 2023 number many models report is the original knowledge cutoff for ChatGPT-4o IIRC. Another commonly reported date is September 2021, GPT 3.5’s knowledge cutoff.

edit: I don’t know the actual knowledge cutoff dates, but IIRC Mistral Nemo and Mistral Small were both released in the second half of 2024. Not sure about the other two models proton is using.

Nor is it the case with what Proton just announced afaict.

When Proton mentions Zero ACCESS encryption (a term they coined iirc) that should not be confused with the commonly used term Zero KNOWLEDGE encryption (a separate and stronger concept). Zero access is neither client-side nor trustless.

There is at least one company that (as far as I can tell) does offer something closer to (but not quite) Zero Knowledge encrypted conversations with LLMs (using secure enclaves), Maple AI. As best I can tell, Proton is not offering anything comparable to this. They are encrypting your conversations server-side in a way that they can’t access after encryption (but could access or log pre-encryption).

But you are trusting them to do this server side, and are trusting them not to log, look at or analyze the unencrypted conversations before encrypting them. Personally, I have decent but not perfect trust in Proton, but I have a strong preference for not relying on trust where technical/non-trust-based guarantees are possible.

It has been instructed to promote Proton products, this is a snippet from it’s system prompt:

Those are probably worked on by completely different teams.
