Claims

63% of AI agent sessions do not use sub-agents at all.
25.9% of sessions use 1 to 5 concurrent sub-agents.
9.8% of sessions use more than 5 parallel sub-agents.
Parallel sub-agents reduce time-to-completion for tasks without increasing HBM memory bandwidth demand.

Key quotes

63% of sessions do not use sub-agents at all, while 25.9% use 1-5 concurrent sub-agents. 9.8% of sessions use over 5+ parallel subagents.

By using parallel subagents, it can speed up a time to finish a task without requiring any more HBM bandwidth.
