Google's Deep Think AI Hits Gold Standard in Math Olympiad
Google's Deep Think AI masters complex problems, prompting urgent new efforts to manage the escalating risks of advanced intelligence.
August 1, 2025

Google is advancing its Gemini artificial intelligence with an enhanced reasoning mode dubbed "Deep Think," a technology designed to tackle complex problems by exploring multiple lines of reasoning simultaneously.[1][2] This development, which has already demonstrated remarkable capabilities in the realm of competitive mathematics, is also prompting Google to publicly address and formalize its approach to the potential risks associated with increasingly powerful AI.[3][4][5] The new Deep Think feature, an upgrade to the Gemini 2.5 Pro model, represents a significant shift from the standard, rapid-response AI. Instead of pursuing a single, linear path to an answer, Deep Think can consider various hypotheses in parallel before delivering a solution, a process Google describes as giving the model more "thinking time."[1][4][2]
The power of this new approach was showcased at the 2025 International Mathematical Olympiad (IMO), one of the world's most difficult and prestigious mathematics competitions for high school students.[3][4] An advanced version of Gemini equipped with Deep Think achieved a gold-medal standard, solving five out of the six exceptionally challenging problems.[4][6] This performance, earning 35 out of a possible 42 points, was officially graded and certified by IMO coordinators.[4][6] Notably, the model accomplished this feat using end-to-end natural language, directly interpreting the problem descriptions and producing rigorous mathematical proofs without the need for specialized formal languages, all within the competition's 4.5-hour time limit.[4][6][7][8] This marks a substantial leap from the previous year, where Google's AI required expert translation and days of computation to achieve a silver-medal standard.[4][8] The success is attributed not only to the parallel thinking architecture but also to training on novel reinforcement learning techniques and a curated database of high-quality mathematical problem solutions.[4]
While celebrating these breakthroughs, Google is also publicly grappling with the safety implications of such advanced AI. The company has introduced a framework for identifying and mitigating novel risks in its AI systems, acknowledging that as models become more capable, the potential for misuse and unforeseen negative consequences grows.[9][10] This "early warning system" is designed to evaluate models for dangerous capabilities, including deception, manipulation, and cyber-offense.[9][10] The concern is that as AI systems become more powerful, they may develop these dangerous skills by default, which could be exploited by malicious actors or lead to harmful actions even without ill intent.[9][10] In a research paper on the topic, Google DeepMind outlined four key risk areas for advanced AI: misuse, misalignment, mistakes, and structural risks.[11] The company stated its strategy involves preventing threat actors from accessing dangerous AI capabilities through robust security and continuous monitoring.[11]
This focus on safety comes amid scrutiny from both internal and external sources. Researchers and AI policy experts have called for greater transparency from major AI labs like Google, arguing that the details provided in safety reports are often sparse and insufficient for independent evaluation.[5] Concerns have been raised that companies are not fully disclosing the extent of their models' capabilities or the results of "dangerous capability" testing, making it difficult to verify safety claims.[5][12] A group of current and former employees from leading AI companies, including Google DeepMind, recently published a letter warning that the pursuit of financial gain is overshadowing safety concerns and that ordinary whistleblower protections are inadequate for addressing the unique risks posed by advanced AI.[12] The letter highlights risks ranging from entrenching existing inequalities to misinformation and even the potential loss of control of autonomous AI systems.[12] Google, for its part, maintains that safety is a core component of its development process, from pre-training on filtered data to internal and external red-teaming exercises designed to stress-test the models for bias, toxicity, and other potential harms.[13][14][15]
In conclusion, Google's introduction of Deep Think marks a significant milestone in the development of more sophisticated AI reasoning. The model's success in the competitive mathematics arena demonstrates a powerful new approach to problem-solving.[3][4] However, this advancement is inextricably linked to the growing urgency of addressing the safety and ethical challenges posed by increasingly capable AI. As Google rolls out Deep Think to a wider audience, starting with trusted testers and Google AI Ultra subscribers, the broader AI community will be closely watching how the company navigates the delicate balance between innovation and responsibility.[4][16] The development of "early warning systems" and public safety frameworks is a crucial step, but ensuring true accountability and mitigating the potential for harm will require ongoing transparency and collaboration between AI developers, researchers, and policymakers.[9][17]
