Google's Gemini 2.5 Flash (Nonthinking) evaluated on most benchmarks

We just evaluated Gemini 2.5 Flash Preview (Nonthinking) on most benchmarks.

Gemini 2.5 Flash Preview (Nonthinking) is a lightweight alternative to Google’s flagship model, Gemini 2.5 Pro Exp. Gemini 2.5 Flash Preview (Nonthinking) runs at a fraction of the cost and latency, rendering it a more accessible option.
Like Claude 3.7 Sonnet (Nonthinking), Gemini 2.5 Flash Preview (Nonthinking) is a hybrid reasoning model, meaning it can adaptively choose how much to think before responding.
Gemini 2.5 Flash Preview (Nonthinking) excels on LegalBench, coming second only to the flagship Gemini 2.5 Pro Exp (and outperforming its own thinking variant, Gemini 2.5 Flash Preview (Thinking), by 1%).
We consistently had difficulty with Google’s API during evaluation, which prevented us from reporting full results. We’re working with a representative from the Gemini team to resolve those issues.
