Just now, Google announced its first hybrid inference model, Gemini 2.5 Flash.
Similar to Claude, the new model’s “thinking budget” is customizable, allowing users to enable or disable Gemini 2.5’s thinking mode.
Notably, disabling thinking mode reduces costs by a staggering 600%, while performance remains comparable to Gemini 2.0 Flash.
Specifically, Gemini 2.5 Flash’s output price is $0.6 per million tokens with thinking disabled and $3.5 per million tokens with thinking enabled.
Naturally, the longer the model “thinks,” the better its performance.
In the GPQA knowledge Q&A benchmark, a 24k thinking budget improved performance by 6%; for coding tasks (LiveCodeBench), a 16k thinking budget yielded the best results.
