 PsyNeuLink is:
 
  - *open source*, freeing users of the costs or restrictions associated with proprietary software.

  ..

  - *computationally general* -- it can be used to implement, seamlessly integrate, and simulate interactions among
    disparate components that vary in their granularity of representation and function (from individual neurons or
    neural populations to functional subsystems and abstract cognitive functions) and at any time scale of execution.

  - *integrative* -- it provides a standard and accessible environment for model comparison, sharing, and documentation;
+
  ..
+
  - *extensible* -- it has an interface (API) that allows it to be used with other powerful tools for implementing
    individual components, such as:
    * Neuron (biophysically realistic models of neuronal function)
    * TensorFlow (ODE's, deep learning);
    * Emergent (broad class of neurally-plausible connectionist models);
    * ACT-R (symbolic, production system models).
