Hy3 is one of the newest open-source reasoning models pushing the limits of efficient AI.

Introduction to Hi 3: A New Open-Source AI

Overview of Hi 3

• China has released an open-source AI called Hi 3, which outperforms models like DeepSeek and competes with larger models such as GPT 5.5 and Claude Opus 4.8.

• The term "open-source" indicates that users can run the AI on their own systems without restrictions.

Key Features of Hi 3

• Hi 3 effectively combines fast and slow thinking, allowing it to determine when to engage in deep reasoning versus providing straightforward answers.

• This efficiency reduces processing time by up to half while maintaining competitive performance against more extensive paid models.

Capabilities Beyond Chat

• Unlike many AIs focused solely on conversation, Hi 3 is designed for complex tasks including long coding jobs, deep research, and multi-step agent tasks.

• It performs exceptionally well in coding and agent benchmarks, rivaling flagship models that are significantly larger.

Integration and Accessibility

• Hi 3 integrates seamlessly with tools like Claude Code and Cursor, enhancing its usability for developers.

• The API for Hi 3 is available for free for a limited time (two weeks), encouraging users to explore its capabilities.
