Researchers from the University of Arizona and others published a NeurIPS 2026 paper revealing that 'information sufficiency' is not enough for successful multi-agent collaboration. Experiments showed identical communication configs yield vastly different results: Qwen 80B sending short messages to 9B improved accuracy in code retrieval but dropped it by 23.6% in tool calling. The team proposes a training-free dynamic strategy that adapts communication choices based on task and receiver model characteristics.

    • Information sufficiency alone does not guarantee success in multi-agent collaboration; communication configurations carry hidden costs.
    • Identical communication strategies yield vastly different results across tasks, improving accuracy by 14.2% in ContextBench but dropping it by 23.6% in ToolSandbox.
    • Proposes a training-free dynamic strategy that adjusts whether/how to communicate and switches receivers based on real-time task and model characteristics.
