Google's Gemini 2.5 Deep Think Earns Gold-Level Score at ICPC World Finals

The company says an agentic, multi-step reasoning approach with code execution propelled the model to solve novel tasks under official rules.

Overview

  • The advanced Gemini variant correctly solved 10 of 12 problems in the 2025 ICPC World Finals, a result Google says would place it second overall against university teams.
  • It cracked Problem C, which no human team solved, by assigning priority values to reservoirs and applying dynamic programming, the minimax theorem, and nested ternary search in about 30 minutes.
  • The run took place live in a remote environment under ICPC guidance with code execution and testing, reaching eight correct solutions in 45 minutes and 10 by 677 minutes.
  • ICPC coordinators scored the submissions, Google has posted the solutions on GitHub, and internal analysis indicates gold-level performance on 2023 and 2024 problem sets.
  • Google credits new training methods, reinforcement learning, and parallel agent workflows for the result, while compute usage and full configuration details remain undisclosed.
