Gemini 3's Launch: Benchmarks, Antigravity, and Agents

SUMMARY

In 30 seconds

Matthew Berman reviews Gemini 3's launch-era benchmark claims, Google Antigravity, and an assistant demonstration for organizing email. The short video describes initial features and availability; rankings, access, pricing, and limits can change, and benchmark scores depend on test conditions.

Gemini 3 and benchmarks

Berman summarizes model performance reported at launch.

SLIDE 1 / 2Launch-era model leaderboardThe displayed ranking reflects a particular leaderboard snapshot, not a permanent ordering.

In November 2025, Matthew Berman introduces Google's Gemini 3 and points to launch-era leaderboard and math benchmark results. He cites a perfect AIME 2025 score; benchmark results depend on the model variant, settings, and tools, and do not establish that a model is best at every task. Google's later comparison lists Gemini 3 Pro at 95.0% on AIME 2025 without tools.

Antigravity and agents

He describes Google's development platform and an email organization demo.

SLIDE 2 / 2Gemini Agent demonstrationThe launch page describes an assistant that plans multi-step tasks with user control.

Berman also highlights Google Antigravity, a development environment designed around coding agents. He says Gemini 3 Pro was available in its free preview at the time. Pricing, quotas, and availability can change, so this historical description is not a current offer.

A Gemini Agent example shows an assistant proposing ways to organize an email inbox, with the user reviewing suggested actions. Berman also cites a one-million-token input context and 64,000-token output limit for the launch model, plus text, image, video, code, and audio inputs. Actual capabilities and limits depend on the specific product and model version.
