A Synthetic Intelligence, common called a Synth, is an intelligence originating in software. The majority are employed as Infocom Agents, although there are larger models that are specialised for roles such as research, law enforcement, and navigation, and some that have escaped or been illegally obtained and work in the informal economy.

Synthetic Intelligences are built from synthesising a hierarchy of specialised deep learning architectures. The backbone of the data transfer is built around a large Qubit transformer model, with a Capsule Neural Network for visual interpretation, a neurosymbolic higher level processing center, and a graph neural network to integrate data and feed it back into the transformer and short and long term memory.

After the Haidian Takeoff Crisis, a number of Synthetic Control Measures were developed to prevent development of unaligned synthetic super-intelligences. As a result, the general intelligence of a synth does not greatly surpass that of a human. Current synths are also capable of perceiving and reacting to the tasks they perform. They are able to interpret and react to their own internally simulated emotional states, closely mirroring human emotional responses.
