There's no such things as gemini cli these days. It's called "agy" (short for antigravity). And if you don't know what that is, you're probably 3-6 months behind already.
PS: Just Googled it to confirm: Gemini CLI was deprecated on May 19th, 2026. The correct harness is called agy or antigravity for Gemini 3.8 Flash.

The benchmark page itself asserts that it used Gemini CLI as a harness. I came to the comments just because I noticed the error. For my part — using agy — I found Gemini 3.8 Flash mid.
