The most visible threads right now are clustered in r/singularity, r/Bard, r/GeminiAI.
Why am I not paying like 200 bucks per month for it? It is the best model ever and destroys any of open ai's models. It feels illegal. Doesn't make sense. Free in ai studio + Best model ever. I love GOOGLE (especially Logan).
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.
