A light classifier screens incoming messages, then a lightweight Gemma model fine-tuned on local scam conversations checks a longer slice of the conversation and warns the user in real time. Data stays on the phone, which matters because end-to-end encrypted chats cannot be scanned on servers. No app name, launch date or accuracy figure was given.","key_facts":["Announced in a Google DeepMind blog post (Oct 14, 2026, Responsibility & Safety; authors JJ Geewax and Miguel de Andrés) and presented at Singapore International Cyber Week 2026; part of Google DeepMind's National AI Partnership with the Singapore Government","Two stages: a lightweight classifier screens incoming messages 'with minimal power use'; a fine-tuned lightweight Gemma model then analyses a larger snapshot of the conversation to confirm or dismiss the threat.

The work was shown at Singapore International Cyber Week and is part\nof DeepMind's national partnership with Singapore, which earlier produced a \"double-blind\" model evaluation with Singapore's AI\nSafety Institute.\n\n## Why it matters\n\nIt is an example of a government using a small open-weight model on devices to fight AI-era fraud without reading people's messages\non a server.
