CognitiveKernel-Pro

One-Minute Overview#

CognitiveKernel-Pro (CogKernel-Pro) is an open-source deep research agent framework from Tencent AI Lab that enables complex research tasks using multiple free tools (only requiring a Google Search API, which can be replaced with DuckDuckGo). The framework provides a fully reproducible SFT training recipe that outperforms RL-based models without requiring reinforcement learning. Researchers and developers can use this framework to build intelligent agent systems capable of conducting deep research.

Core Value: Provides an end-to-end solution for deep research agents, achieving high performance without complex RL training.
