Google has just rolled out two new AI models, Gemini 3.6 Flash and 3.5 Flash-Lite. At the same time, they’re training their next major AI system, Gemini 4. These announcements came on July 21, 2026, adding more options to Google’s expanding lineup. Meanwhile, the highly anticipated Gemini 3.5 Pro is still in testing.

What Google Actually Released
The standout model is Gemini 3.6 Flash, which Google claims is both faster and cheaper than its predecessors. In AI lingo, “Flash” models are the quicker, lighter versions within a family. They handle high volumes of requests more efficiently, much like how economy seats differ from first-class ones. You trade off some capability for speed and cost-effectiveness.
Along with 3.6 Flash, Google introduced Gemini 3.5 Flash-Lite. This model is even more streamlined, perfect for tasks where speed is crucial and costs need to stay low. Consider it for auto-completing forms, creating quick summaries, or powering features in apps where every second counts.
The Cybersecurity AI Angle
Google also unveiled a cybersecurity-focused AI built on the Gemini framework. While they haven’t shared full technical specs yet, this product aims to help security teams analyze threats more quickly. Typically, cybersecurity AI tools scan large amounts of log data, flagging unusual patterns that human analysts may overlook. By entering this space, Google directly competes with Microsoft’s Security Copilot and other AI security solutions for enterprises.
Where Is Gemini 3.5 Pro?
Many developers and power users are eagerly waiting for Gemini 3.5 Pro, but it’s still not available. Google confirmed it’s still in testing. Pro models are the high-capability versions in Google’s lineup, similar to how a professional camera offers more manual controls than a simple point-and-shoot. The ongoing absence of 3.5 Pro stands out because Google has been releasing other models while this key one remains unavailable.
According to Ars Technica’s reporting, Google has already started training Gemini 4. This indicates that the company is moving quickly, even as some current models are still incomplete.
Gemini 4 Is Already in Training
The most exciting news from the announcement is that Gemini 4 is already in training. Training a large AI model involves feeding it enormous amounts of data to learn patterns and relationships. This process usually takes months and requires extensive computing resources. Google’s progress here suggests we could see Gemini 4 launched in the next few months, though no specific release date has been provided.
As 9to5Google mentioned, this release strategy shows just how competitive the AI model race has become. Companies are quickly unveiling updates and teasers to keep up with rivals like OpenAI and Anthropic.
Community Reactions
“Another Flash model while we’re still waiting on 3.5 Pro. At this point I feel like Pro is just marketing. They announce it, everyone gets excited, and then it’s just… not there.”
“The cybersecurity AI is actually the most interesting part of this for me. If it can actually cut through alert fatigue, that would be genuinely useful. Security teams are drowning in noise.”
What This Means for Everyday Users
If you use Gemini through Google products like Gmail, Docs, or the Gemini app, the 3.6 Flash update should make AI responses noticeably faster for routine tasks. Developers building apps on Google’s AI platform might find it cheaper, too.
For everyday consumers, this means Google Assistant-style features in various apps will likely respond more quickly. For businesses and developers, the cheaper and faster Flash models reduce the cost of building AI-powered features, which can lead to more AI integrations in products you already use.
The cybersecurity aspect is more relevant for IT departments and enterprise customers than individual users, at least for the time being.
What To Watch
- Gemini 3.5 Pro release: No specific date has been announced. Google’s past patterns suggest it could arrive within weeks, but the 3.5 generation has already taken longer than expected.
- Gemini 4 timeline: With training underway, keep an eye out for Google to share benchmarks or early access for developers in late 2026 or early 2027.
- Cybersecurity AI details: Google hasn’t released complete technical specs or pricing for its security product yet. Enterprise customers should stay tuned for a dedicated announcement.
- Competitor responses: OpenAI and Anthropic both have model updates coming up. Google’s fast release pace will likely push rivals to speed up their own timelines.
