Proton's Lumo 2.0: AI Meets Unbreakable Privacy

Proton has unveiled Lumo 2.0, a substantial update to its AI assistant that prioritizes user privacy. This new iteration offers advanced features such as reasoning modes, image generation and recognition, live web search with citations, and persistent memory, positioning it as a distinct alternative to services like ChatGPT.

Central to Lumo 2.0's design is its robust privacy stack, combining zero-access encryption for stored chats and images with stringent no-logs and no-training policies. This approach aims to protect user data comprehensively, appealing to privacy-conscious individuals already familiar with Proton's other services.

The updated Lumo 2.0 and its Lite variant demonstrate significant performance gains, scoring considerably higher on AI benchmarks than their predecessors. While Proton cites faster speeds for everyday queries, complex tasks may still require more processing time.

Users can customize their experience with "Custom Lumos," personalized assistants that retain instructions in memory while upholding encryption. Pricing includes a free tier for basic use, a $12.99 monthly plan for unlimited access and advanced features, and a $14.99 per-user professional tier for teams.

Despite its advancements, Lumo 2.0's benchmark scores indicate it is not yet on par with the most advanced frontier models currently available, though it significantly closes the gap with older leading models. Proton leverages underlying technologies such as Qwen 3.5 and GLM 5.2 for its multimodal capabilities.
