Google has expanded its Gemini AI models lineup with three new releases — Gemini 3.6 Flash, 3.5 Flash-Lite, and 3.5 Flash Cyber — each targeting a distinct gap in the market: efficiency at scale, raw speed, and a closely guarded play in AI-powered cybersecurity. The announcements, made on July 21, 2026, arrived on the eve of Alphabet’s earnings report and against a backdrop of intensifying pressure from Chinese rivals and Anthropic’s growing lead in automated code defense.
