Topology & roster
Supervisor-style team design by search. MALBO searches the team-design space: which agent roles, which model per role, which team size. The output is an optimized team for a specific task type. The resulting team can be any topology (supervisor is the primary studied case).

How a typical Supervisor team handles a task
Typical Supervisor layout — schematic, not verified wiring
Task arrives
Human operator directs Supervisor.
The orchestrator routes the work
Supervisor dispatches build work to Worker agent A and dispatches build work to Worker agent B.
The builders execute
Worker agent A and Worker agent B build the work.
Human holds the last word
Human operator holds final approval.

- HumanHuman operator
- OrchestratorSupervisor
- BuilderWorker agent A
- BuilderWorker agent B
Setup order
- 1.Stand up the orchestrator: Supervisor.
- 2.Wire Worker agent A: it receives "dispatches" from Supervisor and sends "reports" to Supervisor. Wire Worker agent B: it receives "dispatches" from Supervisor and sends "reports" to Supervisor.
- 3.Declare the human gate: Human operator holds final approval.

Windowed metrics with provenance. [unknown] means it was not tracked — an honest hole beats an invented figure.
>45% cost reduction on average vs random search with comparable performance. Source: arXiv 2511.11788 [evidence_linked]
Heterogeneous MALBO team vs homogeneous GPT-4 team; comparable task performance. Source: arXiv 2511.11788 [evidence_linked]
Token economics
Cost transparency is part of the honesty architecture. [unknown] means it was not tracked — not that it is zero.
Blueprint
Operational DNA — why it works, how it was built, and how it is overseen. Not files for sale; knowledge of the design.
Bayesian optimization is sample-efficient — it finds good configurations in far fewer trials than random search. Multi-objective formulation explicitly trades off performance vs cost, producing configurations that are not needlessly expensive. Heterogeneous model assignment (different models per role) captures the insight that different tasks within a workflow have different capability requirements.
Python implementation using Bayesian optimization libraries. Task evaluated on a standardized benchmark. Team-design search space: model selection per role, number of agents, role assignments. Pareto-frontier search identifies team designs that are not dominated on both objectives simultaneously.
Multi-objective optimization loop is automated. Human sets the objective weights (performance vs cost tradeoff) and task specification. BO requires significantly fewer evaluations than random search (sample-efficient). Source: arXiv paper.
