Google has released Gemini 3.6 Flash and Gemini 3.5 Flash-Lite, two models designed to run AI agents and high-volume business tasks more quickly and at a lower cost. It also announced Gemini 3.5 Flash Cyber, a specialist model for finding and fixing software vulnerabilities.
Key facts
- Gemini 3.6 Flash is designed for coding, knowledge work and multimodal tasks.
- Google says it uses 17% fewer output tokens than Gemini 3.5 Flash.
- Flash-Lite is designed for high-volume tasks such as search, document processing and summarisation.
- Gemini 3.5 Flash Cyber will be made exclusively available to governments and trusted partners through a limited-access pilot programme.
- Google’s more powerful Gemini 3.5 Pro model remains in testing.
Our take
The release reflects a growing focus on making AI agents faster and more affordable, rather than relying on the largest model for every task. For organisations, the best model may not be the most powerful one. Cost, speed, accuracy and the sensitivity of the information being processed should all be considered when selecting an AI tool.
