OpenCog is a project that aims to build an open source artificial intelligence framework. OpenCog Prime[2] is a cognitive architecture for robot and virtual embodied cognition that defines a set of interacting components designed to give rise to human-equivalent artificial general intelligence (AGI) as an emergent phenomenon of the whole system. OpenCog Prime's design is primarily the work of Ben Goertzel while the OpenCog framework is intended as a generic framework for broad-based AGI research. Research utilizing OpenCog has been published in journals and presented at conferences and workshops including the annual Conference on Artificial General Intelligence. OpenCog is released under the terms of the GNU Affero General Public License.


OpenCog was originally based on the release in 2008 of the source code of the proprietary "Novamente Cognition Engine" (NCE) of Novamente LLC. The original NCE code is discussed in the PLN book (ref below). Ongoing development of OpenCog is supported by Artificial General Intelligence Research Institute (AGIRI), the Google Summer of Code project, and others.


OpenCog consists of:

Relation to Singularity Institute[edit]

In 2008, the Singularity Institute for Artificial Intelligence (SIAI) sponsored OpenCog, resulting in a part-time post-doc Joel Pitt and a full-time system engineer. Many contributions from the open source community have been made since OpenCog's involvement in the Google Summer of Code in 2008 and 2009. Currently the SIAI no longer supports OpenCog.[11] Today, OpenCog receives funding and support from several sources including the Hong Kong government, Hong Kong Polytechnic University and the Jeffrey Epstein VI Foundation.[12]
