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

>> 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?
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
