Google DeepMind has announced the release of three new models in its Gemini Flash series: Gemini 3.6 Flash, 3.5 Flash-Lite, and 3.5 Flash Cyber. These models are designed to meet the growing demands of developers building production AI agents, offering higher token efficiency, lower latency, and more reliable performance.
Gemini 3.6 Flash is positioned as the workhorse model, delivering improved coding, knowledge work, and multimodal capabilities. According to the Artificial Analysis Index, it reduces output token usage by 17% compared to 3.5 Flash, and on benchmarks like DeepSWE, it shows up to 65% reduction in token usage. It is priced at $1.50 per million input tokens and $7.50 per million output tokens, making it more cost-effective than its predecessor. Performance gains include 49% vs. 37% on DeepSWE, 63.9% vs. 49.7% on MLE Bench, and 83.0% vs. 78.4% on OSWorld-Verified. The model also features enhanced Frontier Safety safeguards against CBRN and cyber offense misuses.
Gemini 3.5 Flash-Lite is the fastest model in the 3.5 series, delivering 350 output tokens per second according to Artificial Analysis. It is priced at $0.30 per million input tokens and $2.50 per million output tokens. It significantly outperforms 3.1 Flash-Lite on agentic tasks, with scores of 54% vs. 31% on Terminal-Bench 2.1, 72.2% vs. 60.1% on GDM-MRCR v2, and 1140 vs. 642 on GDPval-AA v2. It even surpasses 3 Flash on several benchmarks, including SWE-Bench Pro (54.2% vs. 49.6%) and OSWorld-Verified (74.0% vs. 65.1%).
Gemini 3.5 Flash Cyber is a specialized model fine-tuned for cybersecurity vulnerability detection and patching. It operates within the CodeMender agent system, using multiple agents to produce combined reports. It achieves competitive performance on the CyberGym benchmark. Due to dual-use concerns, it will be available exclusively to governments and trusted partners through a limited-access pilot program.
Both 3.6 Flash and 3.5 Flash-Lite are available starting today via Google AI Studio, Android Studio, Gemini Enterprise Agent Platform, and the Gemini app. 3.5 Flash-Lite is also rolling out in Google Search. Google DeepMind also noted that Gemini 3.5 Pro is currently being tested with partners and that pre-training for Gemini 4 has begun.
