Multi-Agent Coordination Without Inference-Time Communication
Most modern multi-agent systems coordinate through explicit communication at inference time.
They exchange:
- natural language messages
- structured protocols
- embeddings
- or latent signals
This works, but it introduces latency, overhead, and additional system complexity.
This repository explores a different hypothesis:
What if agents do not need to communicate at inference at all?
What if coordination can be embedded during training?
Behavioral Signal Training (BST) is an exploratory research direction that investigates whether coordination can be learned into internal representations, rather than transmitted through a runtime channel.
This repository is shared to document the idea and invite discussion and critique.
The conceptual framework is described in detail in the working paper:
➡️ BST Academic Format Paper (PDF)
The document formalizes:
- the core hypothesis
- the training setup
- comparisons with existing approaches
- proposed ablations
- evaluation criteria
Instead of teaching agents:
- what another agent says
- or what another agent does
BST proposes training agents on how other agents internally react to shared situations.
The goal is not representational similarity.
The goal is representational compatibility.
If coordination is embedded during training, there may be nothing to transmit at inference.
Behavior triggers behavior.
BST is NOT:
- a production-ready algorithm
- a finished method
- a claim of state-of-the-art performance
BST IS:
- a research hypothesis
- a representational perspective on coordination
- an attempt to remove inference-time communication altogether
The value of this direction depends entirely on empirical validation.
During training:
- agents are exposed to shared environments
- and to behavioral signals derived from other agents’ internal activations
The objective is not to align representations, but to make them functionally compatible for joint behavior.
At inference:
- no messages
- no embeddings exchanged
- no coordination channel
Only local observations and internal state.
- Conceptual framework: defined

Coordination does not have to be transmitted.
It can be trained.
