Every multi-agent AI system has the same problem.
You prompt GPT-4 to research 20 biotech companies across gene editing, drug discovery, and diagnostics. The model spawns agents to handle the task. You wait. And wait. Because despite having the computational capacity to run 100 agents simultaneously, the orchestrator executes them sequentially: agent 1 completes, then agent 2 starts, then agent 3, and so on.

The article discusses how Moonshot AI’s Kimi K2.5 framework addresses the inefficiencies in traditional multi-agent AI systems by enabling parallel execution of tasks through its Parallel-Agent Reinforcement Learning (PARL) approach. It explains the concept of serial collapse, where models default to sequential execution despite being capable of simultaneous processing, and demonstrates how PARL allows for dynamic task decomposition and efficient orchestration, resulting in significant speedups for complex multi-step tasks.
