You possess access to a network comprising 768 Nodes (increasing to 1024 with Negentropy). For every 8 unallocated nodes, your thinking speed escalates by 25% in an additive manner. Nodes are designed to store approximately 5 Petabytes of information.
Thinker powers consume a number of nodes roughly equivalent to their SP plus one (e.g., Thinker 2 requires 3 Nodes, Thinker 3 requires 4 Nodes). Your maximum budget for a Thinker power is 25 nodes.
You can also create Tinker powers that starts with an empty database; You have to fill it with data and nodes according to the square of their SP (e.g., 0 requires 1 point, 3 requires 9 points). Your maximum budget for a Tinker power is 81 nodes.
Hybrid ratings ('Tinker/Thinker 3') generally tend to cost higher than simple abilities but less than the sum of their parts.
