In July, Proton, the company behind Proton Mail, released Lumo, a privacy-
focused AI chatbot. Now, just under a month later, Proton has begun rolling
out Lumo 1.1 to both free and paying users, and according to the company, the
updated assistant "performs significantly better across the board" relative
to its predecessor.

Just how much better is the new version of Lumo? Proton claims it offers a
170 percent improvement in context understanding, meaning the chatbot is able
to more accurately answer questions based on documents and data users share
with it. It's also 40 percent better at generating working code, and 200
percent better at working through multi-step problems, as well as using the
right tools to tackle tricky prompts.

One area where the original release felt like it wasn't up to the level of
the competition was when it came to providing answers about current events.
Thanks to a better web search tool, Proton says Lumo 1.1 should provide more
accurate answers while suffering from fewer hallucinations.

Proton doesn't say how it measured those improvements, but the company did
share a handful of screenshots that compare the responses generated by Lumo
1.1 and 1.0. If nothing else, the new chatbot does a better job of formatting
its answers in a way that's easy to follow.

As before, any conversations you have with Lumo are encrypted, with no logs
shared with Proton or any other company. Proton is also releasing the code
for Lumo's iOS and Android apps so the open source community can verify the
company's security credentials.
