The new model lineup includes Gemini 3.6 Flash and Gemini 3.5 Flash-Lite, updated versions of its lightweight ​offerings, designed for use cases that do not require the most cutting-edge technology. Google also unveiled ​a new lightweight variant, Gemini 3.5 Flash Cyber, which is tailored towards cybersecurity ⁠applications.

But all eyes have been on the launch of Gemini 3.5 Pro, the top-tier version of the ​model, which Wall Street is waiting for as an indicator of whether Google’s DeepMind AI lab is ​able to keep pace with Anthropic and OpenAI.

Gemini 3.5 Pro was originally slated for a June launch, CEO Sundar Pichai said in his keynote address at the company’s I/O developer conference in May.

The company’s launch of the Gemini 3 model family last ​November demonstrated it had returned to the front of the AI race after years as a laggard. ​It caused OpenAI to issue a “code red” internally to concentrate efforts around its competing GPT model.

Google’s main rivals have struck back ‌since ⁠then. Anthropic rolled out its latest Mythos 5 and Fable 5 models, which were deemed so powerful by the U.S. government as to be considered a national security risk.
