Working with experts on 18 research problems, the advanced version of Gemini Deep Think helped solve long-standing bottlenecks in algorithms, machine learning and combinatorial optimization, information theory and economics. The most interesting of ours Article “Accelerating Research with Gemini”. include (relevant section numbers in the article):
- Pushing mathematical boundaries for online puzzles: Progress on classic computer science problems such as “Max-Cut” (efficient network slicing) and “Steiner Tree” (connecting multidimensional points) has slowed. Gemini broke both impasses by thinking outside the box. He solved these discrete algorithmic puzzles by extracting advanced tools—such as Kirszbraun's theorem, measure theory, and the Stone-Weierstrass theorem—from completely unrelated branches of continuous mathematics. See Sections 4.1 and 4.2.
- Resolving decades of online submodular optimization conjectures: A Theoretical article from 2015 proposed a seemingly obvious rule for data streams: making a copy of an arriving item is always less valuable than simply transferring the original. Experts have been trying to prove this for a decade. Gemini has developed a very detailed three-element combinatorial counterexample, rigorously proving that long-standing human intuition is false. See Section 3.1.
- Machine learning optimization: Training AI to filter noise typically requires engineers to manually tune a mathematical “penalty.” Scientists created a new technique that did this automatically, but they couldn't mathematically explain why. Gemini analyzed the equations and proved that the method worked by secretly generating its own “adaptive penalty” on the fly. See Section 8.3.
- Improving economic theory for artificial intelligence: The recent “Revelation Rule” for AI-generating token auctions only worked mathematically when bids were limited to rational numbers. Extending the domain to continuous real numbers invalidated the original proof. Gemini uses advanced topology and ordering theory to extend the theorem to account for continuous real-world auction dynamics. See Section 8.4.
- Physics of cosmic strings: Calculating the gravitational radiation of cosmic strings requires finding analytical solutions to difficult integrals containing “singularities”. Gemini found an innovative solution using Gegenbauer polynomials. This naturally absorbed singularities, collapsing the infinite series into a closed form, a finite sum. See Section 6.1.
Spanning fields from information and complexity theory to cryptography and mechanism design, the results show how artificial intelligence is fundamentally changing research. For details, see our paper.
Given the fluid, conference-driven publication cycle in computer science, we describe these results based on an academic trajectory rather than a rigid taxonomy. About half of these focus on strong conferences – including acceptance of ICLR '26 – while most of the remaining findings will form the basis for publication in future journals. Even when correcting a field by identifying errors (Section 3.2) or refuting assumptions (Section 3.1), these results highlight the value of AI as a high-level research collaborator.
The future of human and artificial intelligence cooperation
Building on Google's previous breakthroughs (1, 2, 3, 4, 5), this work shows that general foundational models – used in agentic reasoning processes – can act as a powerful scientific companion.
Under the guidance of experienced mathematicians, physicists and computer scientists, Gemini Deep Think mode proves its usefulness in fields where complex mathematics, logic and reasoning are at the core.
We are witnessing a fundamental change in scientific workflow. As Gemini evolves, it acts as a “force multiplier” of human intellect, supporting knowledge retrieval and rigorous verification so that scientists can focus on conceptual depth and creative direction. Whether refining evidence, searching for counterexamples, or connecting unrelated fields, AI is becoming a valuable collaborator in the next chapter of scientific progress.
