With respect to the production of pornography, we have split the atom

Playing around with Gemini 2.5 Flash Image (sorry, not calling it that other name) just now, I felt like Oppenheimer staring at the fireball. Such an enormity of new power, so suddenly.

The masturbators of tomorrow will marvel that people were once limited to non-customized pornography.

Seriously, I think this changes everything.

Google just dropped a new Agentic Benchmark: Gemini 3 Pro beat Pokémon Crystal (defeating Red) using 50% fewer tokens than Gemini 2.5 Pro.

I just saw this update drop on X from Google AI Studio. They benchmarked **Gemini 3 Pro** against **Gemini 2.5 Pro** on a full run of **Pokémon Crystal** (which is significantly longer/harder than the standard Pokemon Red benchmark).

**The Results:**

**Completion:** It obtained all 16 badges and defeated the hidden boss Red (the hardest challenge in the game).

**Efficiency:** It accomplished this using **roughly half the tokens and turns** of the previous model (2.5 Pro).

This is a huge signal for **Agentic Efficiency.** Halving the token usage for a long-horizon task means the model isn't just **faster** ,it's making better decisions with less "flailing" or trial and error. It implies a massive jump in planning capability.
