Proton claims their “Lumo” to be a fully open course AI chatbot. Luckily, there is @dingemansemark.bsky.social ’s European Open Source AI Index that makes clear that Lumo is in fact “the least open 'open' model” that they have seen so far. osai-index.eu/news/lumo-pr...
Don't trust Proton.
This is really disappointing as I have been a Proton user for a long time.
Lumo isn't a model; it uses open models, including the model listed as the best for openness in this piece. You can find the models Lumo uses in our privacy policy: proton.me/support/lumo...
We have updated our post. Will you update your marketing materials to tone down the open-washing? osai-index.eu/news/lumo-pr... #OpenWashing
As far as I've found, Lumo is just a wrapper around a few external LLMs (they mention Nemo, OpenHands 32B, OLMO 2 32B, and Mistral Small 3). Seems like Marketing fucked up and was unaware of the terminology used for AI Policy or Engineering. Still not a great look.
Not unaware. @proton.me knows privacy and FOSS concerns are key to its userbase; their users have pointed out the wrong claims from day 1, yet Proton has doubled down, saying (astonishingly) the statement merely reflects a "long-term intention" 😂 discuss.privacyguides.net/t/proton-mar...
