It operates at lower cost and includes enhanced safeguards against misuse in sensitive domains.

Gemini 3.5 Flash Lite focuses on low latency and high throughput workloads, producing up to 350 output tokens per second. It is the most cost-effective model in the 3.5 class and is designed for tasks such as search and document processing.

Gemini 3.5 Flash Cyber is a security-focused model created for identifying and resolving software vulnerabilities. It is being released through a limited access pilot for governments and trusted partners.

The company also confirmed that testing continues for Gemini 3.5 Pro, which has not yet been publicly released. Work has already begun on Gemini 4, described as DeepMind's most ambitious training run to date.
