TLDR: Aime is a novel multi-agent framework designed to overcome the limitations of traditional ‘plan-and-execute’ AI systems. It introduces a Dynamic Planner for adaptive strategy, an Actor Factory for on-demand specialized agent instantiation, and a centralized Progress Management Module for coherent state awareness. This allows Aime to dynamically adjust plans, create tailored agents, and ensure efficient communication. Experiments show Aime consistently outperforms state-of-the-art specialized agents across general reasoning, software engineering, and web navigation benchmarks, demonstrating superior adaptability and task success rates.
In the rapidly evolving landscape of Artificial Intelligence, Multi-Agent Systems (MAS) powered by Large Language Models (LLMs) are emerging as a powerful approach to tackle complex problems. These systems involve multiple AI agents collaborating to achieve a common goal, much like a team of experts working together. However, a common challenge in current MAS designs, particularly those following a ‘plan-and-execute’ model, is their rigidity. This traditional approach often suffers from static plans, fixed agent capabilities, and communication inefficiencies, making them less adaptable in dynamic environments.
A new framework called Aime has been introduced to overcome these limitations. Developed by a team of researchers from ByteDance, Aime offers a novel approach to multi-agent collaboration by enabling dynamic, reactive planning and execution. Instead of a rigid, predefined workflow, Aime operates on a principle of continuous adaptation, allowing both task allocation and agent capabilities to evolve based on real-time feedback.
Aime’s Core Innovations
Aime’s strength lies in its four core components, which work together seamlessly:
- Dynamic Planner: This acts as the central brain, continuously refining the overall strategy based on live feedback from the agents. It breaks down high-level objectives into smaller tasks and adapts the plan as new information comes in, unlike traditional planners that remain static once a plan is set.
- Actor Factory: This innovative component allows for ‘Dynamic Actor Instantiation.’ Instead of using a fixed set of general-purpose agents, the Actor Factory assembles specialized agents on-demand. When a specific subtask arises, it creates a tailor-made agent equipped with the precise persona, knowledge, and tools needed for that particular job. This ensures agents are always perfectly suited for their tasks, enhancing flexibility and robustness.
- Dynamic Actor: These are the autonomous agents that execute the specific subtasks assigned by the Dynamic Planner. Each actor uses a ‘Reasoning and Action’ (ReAct) framework, allowing it to think, act (often by using tools), and observe the outcome in an iterative cycle until its subtask is complete. They can also proactively report progress, providing real-time updates.
- Progress Management Module: This serves as the central hub for system-wide coordination and shared memory. It maintains a clear, real-time view of the entire task hierarchy and the status of all subtasks. This centralized record ensures that all components, from the planner to the actors, have a consistent understanding of the overall progress, minimizing communication breakdowns and redundant work.
How Aime Works
The Aime framework follows an iterative workflow. It starts with a user request, which the Dynamic Planner breaks down into subtasks. The Actor Factory then instantiates a specialized Dynamic Actor for each subtask. This actor executes its task, continuously reporting progress to the Progress Management Module. Once a subtask is completed, the actor reports the outcome to the Dynamic Planner, which then evaluates it, updates the global plan, and dispatches the next subtask. This cycle continues until the main user request is fulfilled.

Impressive Performance Across Diverse Tasks
The researchers put Aime to the test across a variety of challenging benchmarks, including general reasoning (GAIA), software engineering (SWE-bench Verified), and live web navigation (WebV oyager). The results were compelling: Aime consistently outperformed even highly specialized state-of-the-art agents in their respective domains. For instance, on GAIA, Aime achieved a 77.6% success rate, demonstrating its ability to adapt strategies for complex problems. In software engineering, it resolved 66.4% of issues on SWE-bench Verified, showcasing its dynamic agent instantiation capabilities. On WebVoyager, Aime achieved an impressive 92.3% success rate, proving its resilience in dynamic web environments where fixed plans often fail.
This superior adaptability and task success rate position Aime as a more resilient and effective foundation for multi-agent collaboration. The framework represents a significant step towards building more intelligent and autonomous systems that can handle the complexities of real-world dynamic environments.
