Google has quietly released three new Gemini models — 3.6 Flash, 3.5 Flash-Lite, and a restricted cybersecurity variant — but the company's flagship Gemini 3.5 Pro remains stuck in testing limbo. The updates come without fanfare, and the search giant is already dropping hints about a future Gemini 4.
The new arrivals
Gemini 3.6 Flash is the most notable addition. It's a faster, lighter version of the existing 3.5 Flash, designed for tasks that need quick responses without heavy compute. Google says it's optimized for real-time applications like chatbots and code completion.
Then there's Gemini 3.5 Flash-Lite, a stripped-down model for edge devices and low-resource environments. It's meant to run on phones and IoT hardware, bringing AI inference closer to the user.
The third model is a restricted cybersecurity variant. Google hasn't detailed its capabilities, but the model is locked down — likely to prevent misuse in offensive security or malware generation. It's available only through Google's enterprise cloud platform with additional access controls.
Where is Gemini 3.5 Pro?
Gemini 3.5 Pro, the model many developers have been waiting for, is still missing. Google first teased it months ago, but it's been stuck in testing. The company hasn't said why, but insiders point to quality and safety hurdles. The model was supposed to bridge the gap between the Flash series and the full Gemini Pro, but for now, it's in limbo.
Developers who were hoping for a mid-range Pro model are left with the Flash variants or the full Gemini Pro, which is more expensive and slower. The absence of 3.5 Pro leaves a gap in Google's lineup — especially as competitors like OpenAI and Anthropic keep shipping new models.
Teasing Gemini 4
While Google hasn't announced Gemini 4, the company is quietly teasing it. References to the next-generation model have appeared in internal documents and developer forums. The model is expected to be a major leap, possibly with multimodal capabilities and better reasoning. But Google is being careful not to overpromise — the company has been burned before by hyping models that then get delayed.
The cybersecurity model's release suggests Google is also thinking about safety and regulation. By offering a restricted model, the company can claim it's being responsible while still pushing the technology forward.
For now, the question on everyone's mind: when will Gemini 3.5 Pro actually ship? And what will Gemini 4 look like when it finally arrives? Google isn't saying — but the quiet releases suggest the company is moving fast, even if it's not talking.
