Deep Think is available in the Google Gemini App. How to try it.
Google is rolling out Gemini 2.5 Deep Think in the Gemini app, bringing its AI reasoning model to Google AI Ultra subscribers. Subscribers to the AI subscription, which costs $250 per month, will be granted access to Deep Think starting Friday, August 1. Deep Think was first revealed at Google I/O 2025, where the tech giant introduced the model designed for complex math and coding. The AI reasoning model is reportedly Google's most advanced model so far, with higher reasoning capabilities and the ability to solve complex problems using parallel thinking techniques. In its official announcement, Google said that Deep Think provides "more detailed, creative and thoughtful responses" to prompts.

The company says that Gemini 2.5 Deep Think outperforms competing AI models, using scores from Humanity’s Last Exam (HLE), a complex AI test, as a benchmark. According to Google, its model scored 34.8% on the test, which features questions about math, sciences, and humanities. On the other hand, xAI's Grok 4 scored 25.4% and OpenAI's o3 scored 20.3%. Google's model also outperformed AI models from xAI and Anthropic on LiveCodeBench6, a test consisting of coding tasks.
Google also announced that it is releasing the official version of its Gemini 2.5 Deep Think model, which achieved a gold-medal standard at the International Mathematical Olympiad (IMO) earlier in July. The company will offer this version to a select group of "trusted testers", which includes mathematicians and academics. The president of IMO called Deep Think's solutions "astonishing in many respects."
