What is Duck.ai and how does it use GPT‑5?
DuckDuckGo has quietly rolled out GPT‑5 access through its new platform Duck.ai, offering users a privacy-first experience with multiple AI models. The announcement, made via X (formerly Twitter), highlights that the service is free, anonymous, and requires no sign-up, making it one of the most accessible AI portals currently available.
Duck.ai allows users to interact with OpenAI’s GPT‑5, alongside other models like GPT-4o mini, in a clean, distraction-free interface. The platform is designed to appeal to users who value privacy, simplicity, and model diversity.
How does Duck.ai protect user privacy?
Unlike many AI platforms that require account creation or track usage, Duck.ai is anonymized by DuckDuckGo, meaning no personal data is stored or shared.
This aligns with DuckDuckGo’s long-standing commitment to privacy-first search and browsing, which has earned it a loyal user base of over 100 million monthly searches.
The platform does not log queries, store chat history, or require cookies—making it ideal for journalists, researchers, and casual users who want zero-trace AI access.
Why is GPT‑5 access important?
GPT‑5 is OpenAI’s most advanced model to date, featuring multimodal capabilities, longer context windows, and improved reasoning.
While many platforms restrict GPT‑5 to paid tiers or enterprise use, Duck.ai offers open access, democratizing cutting-edge AI for the public.
