Free Google AI Pro for a Year: Does Gemini 3.7 Flash Really Deliver?

01 Installation

Antigravity replaces the discontinued Gemini CLI. On Windows the tool is installed with a single PowerShell command:

irm https://antigravity.google/cli/install.ps1 | iex

Running agy opens a color‑theme selector; the default lower‑right setting is “Gemini 3.7 Flash · high”. The distribution includes five forms—CLI, desktop app, IDE, IDE plugin, and SDK—available at antigravity.google/download.

02 Usage

The top banner shows version, signed‑in account (Google AI Pro badge), selected model, and working directory. Queries trigger an automatic WebSearch and return a structured Chinese answer.

Model selection menu lists Gemini 3.7 / 3.6 / 3.5 Flash, 3.1 Pro, Claude Sonnet / Opus 4.6, and GPT‑OSS 120B. Each model can be set to an effort level—low, medium, or high—so lightweight tasks consume fewer quota units while demanding tasks run at the highest quality.

03 Quota Usage

After completing the workflow the /usage page reports:

Gemini group: weekly quota remaining 98.43 %, 5‑hour quota remaining 90.58 %.

Claude / GPT group: weekly quota remaining 93.18 %, 5‑hour quota remaining 79.55 %.

The Gemini group executed the full workflow while consuming less than one‑tenth of its 5‑hour quota; the Claude/GPT group had previously exhausted more quota on other experiments.

04 Analysis

Quota efficiency does not imply weaker models. Using the Artificial Analysis AA‑AnalystAgent, which runs 80 tasks five times each, the full‑match rates were:

Gemini 3.7 Flash (high) – 60.0 % (rank 1).

Claude Opus 5 (max) – 53.8 %.

GPT‑5.5 (xhigh) – 50.0 %.

The Flash‑positioned Gemini model outperforms other flagship models on agent tasks, achieving higher accuracy while consuming far less quota, indicating superior cost‑effectiveness rather than reduced capability.

05 Free‑Year Access

The free one‑year Google AI Pro program can be claimed at:

gemini.google/students/

It is a student‑only channel with an online verification process; users should monitor auto‑renewal settings when the free period ends.

06 Conclusion

Testing confirms that the free membership provides strong performance. Integrating the AI into actual workflows rather than casual chat yields tangible productivity gains. Antigravity and Gemini 3.7 Flash have returned, and the author plans continued long‑term use.
