Google released Gemini 2.5 Pro with Deep Think on June 22, and the benchmarks are not close anymore. They are not even in the same building.

Here are the numbers: 89.8 percent on MMLU-Pro. 82.4 percent on GPQA Diamond. GPQA is the science one: the test where you need actual knowledge, not pattern-matching. Gemini is outrunning Claude and OpenAI at science. At reasoning. At the stuff that matters most.

Deep Think is the change. It is not just more parameters. It is a different way of thinking: more time to consider, more paths to explore, more willingness to backtrack and try again. It is what Anthropic and OpenAI have been chasing too, but Google got there first this time.

The practical effect is that Gemini 2.5 Pro is now the model you reach for if you need to do something hard. Not because it is flashy. Because it works.

What is interesting is the gap. Benchmarks are not reality, but they are a signal. They tell you where the frontier actually is right now. And right now, the frontier is: Google is in front on this dimension.

For the market, this matters. OpenAI and Anthropic are both filing to go public. Both are racing to show they have the best model. Then Google shows up with better scores on reasoning and science. The narrative shifts.

For users, what shifts is which model you use for homework, for research, for work that requires actual thinking instead of just fluent response.

Google has been quiet on AI compared to OpenAI and Anthropic. They have been building. They just showed their hand, and it is strong.
