What Makes Brain Simulator Unique?

Brain Simulator II is a free, open-source software project aimed at creating Artificial General Intelligence (AGI). Many important features set it apart from other Artificial Intelligence software:

  • The AGI Strategy: With the primary assumption that no one knows specifically how to create AGI, the Brain Simulator implements an experimental platform with a general AGI model which is easy to revise. Several spiking neuron models based on biological neurons combine with software “Modules” to create any desired functionality for rapid experimentation.
  • Snappy Easy User Interface: The graphical display of neurons and Modules lets users explore and modify the internal workings of the Network in real time.
  • Powerful Spiking Neuron Engine: Tested with a billion neurons, the Brain Simulator can process up to 2.5 billion synapses per second on a desktop computer. Networks can also be distributed across a LAN with estimates of neocortex equivalence with only 160 servers.
  • AGI Modules and Applications: To speed AGI development, over 50 Modules perform a variety of AI tasks. Combined with the Neuron Engine, applications already demonstrate vision, mobility, internal modeling, language, and planning.

The Brain Simulator implements an artificial entity named “Sallie” who lives in a simulated world and can integrate input from multiple senses. She can recognize objects with binocular vision and associate them with words she hears, plan a sequence of actions, and manipulate objects to achieve a goal. As she advances to understanding her world, interfaces already exist for cameras, microphones, and robotic control to bring AGI to life.


  • Millions of neurons on your desktop. Processing in real time!
  • Create networks from scratch or from a library of functions.
  • Seamlessly spread huge neuron arrays across a multiple servers.
  • More than 50 modules for speech, vision, and robotic controls.
  • Universal Knowledge Store (UKS) stores ANY kind of information in links equivalent to synapses.
  • Write your own modules.

Strategy: BrainSim's simple 2D and 3D simulators sidestep complexity starting with just a few object types, a few possible attributes, and a few relationships. Once these work well, modules can be expanded to learn new objects, attributes, and relationships as they are encountered within the environment.

Objective: Intended to create an end-to-end AGI system with modules for vision, hearing, robotic control, learning, internal modelling, and even planning, imagination, and forethought. Focused on building a system which can learn about object permanence, spatial relationships, and time/causality. The incremental development strategy is creating the simplest ideas first.
