6x the price of 3.1 flash lite
Compare to the GPT-5.5 announcement: https://openai.com/index/introducing-gpt-5-5/
They continue to focus on smaller models while openai and anthropic are increasing compute requirements for their SOTA models.
They are just refining their current models while they finish training the next generation.
They will all come out at about the same time. Anthropic, OpenAi, Google, xAI

Though 3.1 took 3 minutes of thinking to generate, but it only one that got animated movement.
Gemini 3.5 Flash: $0.75 input / $4.50 output per 1M tokens, 1M context window. The output price explicitly "includes thinking tokens" — which is why it's higher than a typical flash-class model.
For comparison within the Gemini lineup: - Gemini 2.5 Flash: $0.30 / $2.50 - Gemini 3.1 Flash-Lite: $0.25 / $1.50 - Gemini 3.1 Pro Preview: $2.00 / $12.00
So 3.5 Flash is ~2.5x more expensive input vs 2.5 Flash. The pricing and "including thinking tokens" framing position it as a reasoning-capable flash model rather than just a pure speed optimization.
(I suspect you're viewing the "flex" pricing).
Feels like the AI pricing noose is tightening sooner rather than later.
3x price increase over 3 Flash is not something I expected. In fact 3.5 Flash was more expensive than 3.1 Pro to run the Artifical Analysis test suite. $1551 for 3.5 Flash vs $892 for 3.1 Pro. That's 74% more cost while ranking lower. It's 2.5x as fast but I don't think the bang for the buck is there anymore like it was with 3.0 Flash. I'm a bit bummed out to be honest.
One interesting point to note is that Google marked the model as Stable in contrast to nearly everything else being perpetually set as Preview.
