Google has expanded its Gemini AI lineup with three new models designed to deliver faster performance and lower costs for developers and businesses. The company introduced Gemini 3.6 Flash, Gemini 3.5 Flash-Lite, and Gemini 3.5 Flash Cyber, while confirming that Gemini 3.5 Pro is still being tested and will be released when it is ready.
Google on Tuesday unveiled three new Gemini AI models, focusing on speed, efficiency, and specialised capabilities while its flagship Gemini 3.5 Pro remains unavailable.
The new lineup includes Gemini 3.6 Flash, Gemini 3.5 Flash-Lite, and Gemini 3.5 Flash Cyber. Gemini 3.6 Flash is designed for coding, knowledge-based work, and multimodal tasks. According to Google, it reduces output token usage by up to 17% compared with Gemini 3.5 Flash, helping developers improve efficiency without compromising performance.
Gemini 3.5 Flash-Lite is the fastest model in the 3.5 series, capable of generating up to 350 output tokens per second. It is designed for high-volume workloads where speed and cost efficiency are the top priorities.
Google also introduced Gemini 3.5 Flash Cyber, a cybersecurity-focused model that works with the company’s CodeMender code security agent to identify and help fix software vulnerabilities. The model will initially be available only to governments and trusted partners.
Gemini 3.6 Flash and Gemini 3.5 Flash-Lite are now available through the Gemini API, Google AI Studio, the Gemini Enterprise Agent Platform, and the Gemini app.
Google did not announce a release date for Gemini 3.5 Pro, which was expected to launch in June. The company said the model is currently being tested with partners and will be made broadly available as soon as it is ready. Reports suggest the delay is linked to the model falling short of some internal performance targets, particularly in coding.
Google also confirmed that training for Gemini 4 has begun, signalling that development of its next generation of AI models is already underway.
