Abstract: This paper analyzes the integration of Claude Haiku 4.5, a state-of-the-art language model developed by Anthropic, into DuckDuckGo's Duck.ai platform. Duck.ai is an AI chat tool that guarantees full user privacy by anonymizing interactions and not storing personal data. With the incorporation of Claude Haiku 4.5 as the default free model, the platform achieved a significant qualitative leap: the new model offers near-frontier performance, with more than twice the speed and one-third the cost of its predecessor Claude Sonnet 4. The paper describes the technical characteristics of Claude Haiku 4.5, Duck.ai's privacy guarantees, the available model structure (including subscription plans), and discusses the implications of this advancement for users seeking efficient, secure, and accessible artificial intelligence. The work builds on the pioneering study by SANCHES (2024), which documented the DuckDuckGo AI Chat ecosystem in its original configuration, and extends that analysis in light of the developments observed in 2025.
