OpenAI’s GPT-5 and DeepMind’s Gemini have demonstrated advanced reasoning and problem-solving. GPT-5 excels in coding, writing, and complex reasoning, while Gemini achieved gold-medal performance at the 2025 International Mathematical Olympiad. These achievements illustrate that AI can now handle tasks previously limited to top human experts. While still narrow AI, such milestones indicate significant progress toward machines capable of general intelligence and more autonomous problem-solving.
