Gemini 2.5 Pro r/singularity 1,049 upvotes 114 comments December 15, 2025
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.
