Recent advancements in AI models are shifting focus from solely increasing training data and parameters to optimizing test-time compute. This involves strategies that allow models to 'think longer' after receiving a prompt, leading to significant performance gains on complex reasoning tasks without requiring additional training. Models like Claude Opus 5.5 and GPT-5.6 Sol are now incorporating these 'thinking' capabilities by default, utilizing techniques such as sequential thinking, self-consistency, and search-based methods to improve accuracy and efficiency.
