Google launches Gemini 3.6 Flash and 3.5 Flash-Lite, teases Gemini 4

AI-summarised brief · reviewed before publication

Google has launched Gemini 3.6 Flash and Gemini 3.5 Flash-Lite, alongside a specialized security model, Gemini 3.5 Flash Cyber. Gemini 3.6 Flash improves token efficiency by 17% and lowers pricing to $1.50 per million input tokens. It demonstrates enhanced coding precision, achieving 49% on DeepSWE, and updates its knowledge cutoff to March 2026. Gemini 3.5 Flash-Lite targets high-throughput tasks with a price of $0.30 per million input tokens, significantly outperforming its predecessor in agentic and long-context benchmarks. The new Flash Cyber model, built on the Flash foundation, aims to detect and patch code vulnerabilities at scale. It is currently available to governments and trusted partners via a limited-access pilot program using the CodeMender tool. Both new Flash models are immediately available in the Gemini app, Google Antigravity, AI Studio, and Android Studio. Google confirmed that Gemini 3.5 Pro remains in partner testing. Additionally, the DeepMind team announced it has begun pre-training for the next-generation Gemini 4 model, marking their most ambitious training run to date.

💡 Why It Matters

  • · The introduction of a dedicated security-focused AI model signals a strategic shift toward automated, large-scale vulnerability management for critical infrastructure.
  • · By decoupling security tasks from general-purpose models, Google enables specialized, cost-effective defense mechanisms that operate ahead of potential exploits.
