Google Ships Three Gemini Flash Models, Teases Gemini 4

Google put out three new models on July 21 and left the one everyone is waiting for on the shelf. Gemini 3.6 Flash, Gemini 3.5 Flash-Lite, and a security-tuned variant called Gemini 3.5 Flash Cyber all arrived together, a fast and cheap trio aimed squarely at the workhorse end of the market. The flagship Gemini 3.5 Pro, promised for June and delayed more than once, was again absent.

The headline release is Gemini 3.6 Flash, the direct successor to the 3.5 Flash model Google showed at its developer conference. Its pitch is efficiency rather than raw power. Google says it burns roughly 17 percent fewer output tokens than 3.5 Flash on the Artificial Analysis Index and takes fewer reasoning steps and tool calls to finish multi-step jobs. It is priced at $1.50 per million input tokens and $7.50 per million output, down from the $9 the previous Flash charged on output, and its knowledge cutoff jumps more than a year, from January 2025 to March 2026.

Flash-Lite covers the cheapest, highest-volume tasks. The odd one out is Flash Cyber, a model tuned for security work such as hunting bugs in code, which Google is restricting to governments and trusted partners rather than releasing to everyone. A capable bug-finder is also a capable bug-exploiter, and Google is keeping this one on a short leash.

The Pro problem

None of this settles the question hanging over the lineup. Gemini 3.5 Pro was supposed to headline this stretch of the year, and it has now missed target after target. Google has said the model needed a full rebuild, and the company is clearly happy to keep shipping smaller, faster models while it works. That is a reasonable strategy when most real usage is cost-sensitive, but it leaves rivals room to claim the top of the benchmark tables.

Buried in the same announcement was the more interesting signal. Google said it has already begun what it calls its most ambitious pretraining run yet, for Gemini 4. Read one way, that is confidence. Read another, it suggests the company may be looking past the troubled 3.5 Pro entirely and putting its weight behind the next generation. Either way, the Flash models are what you can actually use today, and on price they are hard to argue with.
