We’ve run all our benchmarks for Gemini 3 Flash (12/25) and found it continues to excel!

Congrats again to Google on the release!

Dec 17, 2025

We evaluated Gemini 3 Flash (12/25) and found strong performance at a small fraction of a cost of other frontier models like GPT 5.2 and Claude Opus 4.5 (Thinking).

While the model doesn’t achieve SOTA performance on any of our evaluations, it certainly comes close! It places second on SAGE , only 0.2% behind Claude Opus 4.5 (Thinking) for less than a tenth of the cost per token!

Incredibly, Gemini 3 Flash (12/25) outperforms Gemini 3 Pro (11/25) according to our comparison page

Congratulations to the Google team on another outstanding model!
