[... Lumo] is the least open "open" AI assistant that we have ever added to our index. One of our reasons for inclusion is an openness claim: a model provider that calls their system "open" or "open source" or a variation on that. Lumo is "open" in that sense (Proton calls it open source) but in no other way. Nothing about it is currently open. [...]

Lumo isn't a model; it uses open models, so this is a strange comparison. You can find the models Lumo uses in the privacy policy:  https://proton.me/support/lumo-privacy

Additionally, as others have pointed out, the client apps are open source as well.

I was really pissed by Proton's marketing on this one. It is so closed and opaque, only the client are open. This is clearly open washing marketing!

They are working really hard to destroy their reputation and user's trust. Without trust, however, their (old) business model is dead.

I know I should just move from proton to another service but dammit I finally got transitioned to their email service. I'm so tired of having that trust betrayed.

I'm dreading migrating my SimpleLogin stuff to fastmail >.>

They deleted my message when I said that Luma is not actually private (I didn't know this community was company run).

No cloud LLM can be private (unlike email or even cloud storage), only a locally run LLM can be truly private.

I'm pretty sure they've forgotten about this comm.

Yes this community is run by Proton.

if you can find the receipts in the mod log do post it to !yepowertrippinbastards@lemmy.dbzer0.com .

Good to gather evidence.

Yes this community is run by Proton.

I'm pretty sure this one's not though: there are two "communities" lists, one for ones run by proton and one for "user-supported" ones that aren't run by proton. And well, this one has actually been removed even from the second list so I really doubt they have much involvement here.

At the moment I have been pretty satisfied with the LLMs that Kagi is offering in their standard their for my low requirement queries. Supposedly most of the apis they use are too alternative servers that host instances of the models, some claiming they don’t use your data. I am not aware to what extend open source is serviced in those models, but I have little interest in Lumo for the time being. Can someone explain to me why open source matters for LLMs?

LLM are becomming widely used and whoever controll the LLM training control people lives to some extends. It's crazy how people are relying more and more on ChatGPT for conveniance, some even think it is actually intelligent/smart (it is not). LLM have biais because training data and training recipes are not neutral. Governments and big corpos can use this to extend control and manipulate/influence opinion, behavior, etc... They can choose how and what to censor, the point of view of information that could change user perception of it. With closed data and training recipe we can not see how it is made and what rules the models have been following.

Most open source model only publish the finally wieght model. No training data (mainly because they violate IP, copyright, etc... if you ask me) nor the training recipe, so you only have the possibility to host the model yourself. They slap Open Source on it and voilà... but it often isn't and when it is you can see that it perform worse (because they haven't read all Sci-Hub and Z-Library unlike Llama and ChatGPT for exemple.
