Google releases two new Gemini models, but still no Gemini 3.5 Pro

Google released Gemini 3.6 Flash, Gemini 3.5 Flash-Lite, and a specialized cybersecurity model Gemini 3.5 Flash Cyber on July 21, while delaying the long-awaited Gemini 3.5 Pro, which remains in testing with partners. The new models aim to provide developers with efficiency and low latency for AI agents, with Gemini 3.6 Flash priced at $1.50 per million input tokens and $7.50 per million output tokens, and Gemini 3.5 Flash-Lite at $0.30 per million input tokens and $2.50 per million output tokens.

In a July 21 blog post https://blog.google/innovation-and-ai/models-and-research/gemini-models/gemini-3-6-flash-3-5-flash-lite-3-5-flash-cyber/ , Google announced Gemini 3.6 Flash and Gemini 3.5 Flash-Lite, describing them as built to give developers the "efficiency, low latency, and reliability" needed to run AI agents at scale. The post also detailed Gemini 3.5 Flash Cyber, a specialized model paired with Google's CodeMender security agent. Our big Guessing Game is back Enter now for a chance to win an Apple Watch .

It's against this backdrop that Google announced its new trio of Gemini models. Terms of Use https://www.ziffdavis.com/terms-of-use and Privacy Policy https://www.ziffdavis.com/ztg-privacy-policy . According to the post, Gemini 3.6 Flash is positioned as the company's general-purpose "workhorse" model, offering improvements in coding, knowledge work, and multimodal tasks compared to 3.5 Flash. Google also priced the model lower than 3.5 Flash, at $1.50 per million input tokens and $7.50 per million output tokens. Google released benchmark evaluations of Gemini 3.6 Flash, showing improvements in a variety of domains. Gemini 3.5 Flash-Lite, meanwhile, is billed as the fastest model in the 3.5 series, reportedly capable of 350 output tokens per second, per Artificial Analysis figures cited in the post, at a lower price point of $0.3 per million input tokens and $2.5 per million output tokens. Google writes that the model is intended for high-throughput, latency-sensitive workloads like agentic search and document processing, and that it outperforms the prior Flash-Lite generation across agentic benchmarks. The most narrowly targeted release, Gemini 3.5 Flash Cyber, is designed specifically to detect and patch software vulnerabilities and is being deployed inside CodeMender, Google's code security agent. Per the post, the model will not be broadly available; Google says it plans to offer it exclusively to governments and select partners through a limited-access pilot, citing the dual-use risks associated with a model capable of finding security flaws. Google also said the newly released 3.6 Flash model includes expanded safety measures to resist jailbreak attempts related to chemical, biological, radiological, and nuclear misuse, as well as cyber offenses, while aiming to avoid unnecessary refusals for legitimate use cases.
