Kind of light on details. "Lumo is based upon open-source language models". Okay. Which ones? [Edit: they offer more details at https://proton.me/support/lumo-privacy : "The models we’re using currently are Nemo, OpenHands 32B, OLMO 2 32B, and Mistral Small 3"]

Not sure how I feel about this. I figured Proton would find some clever way to run models on encrypted data, or at least do something akin to Apple's "private cloud compute" but...nope, just another cloud platform like any other. Zero-logging is all fine and good, but don't pretend like you can't access my chats when the only thing stopping you is your logging policy.

Web search — If you ask it to, Lumo can search the web for new or recent information to complement its existing knowledge.

Again, no details. So you're not sharing my data, but you are potentially leaking it to unnamed search engines? Cool, cool.

Oh, and it has built in Proton Docs integration, in case you wanted to accidentally send your documents, unencrypted, through Proton's servers. And also maybe leak their contents to a third-party search engine, who knows?

Please, Proton. E2EE or GTFO. The world doesn't need another chatbot. If you can't do it right, just don't do it.

privacy first

model is not open source

trust me bro we don't share your data

And to where exactly are the servers moving? And why do they still have a Twitter link?

Transparency is key!

god andy yen is just the worst; he continues to ruin proton any way he can.

Another company I won't touch again then

Did Proton train their own LLM or is it a Mistral model?

Ever since Proton went MAGA their presence has just gotten weirder. This is another giant step in a direction nobody wanted.

Glad I dropped them.

No dark mode 👎

disgusting

I don’t get it? This is more about a chatbot service than about LMM, right? It doesn’t sound like they release the model, which would mean it’s less privacy-friendly than running R1, Qwen3, Llama, Mistral or Gemma3 on your own machines. Google and Meta honestly offer better privacy with Gemma and Llama.

Edit: Okay, "Private LLM Called Lumo" is what the title of this post says, that has nothing to do with what Proton wrote. Proton only wrote that it won’t be used to train LLM.

I’ll still stick to Ollama + https://github.com/n4ze3m/page-assist

Proton is dead, who cares.
