AutoAct

AutoAct is an automatic agent learning framework that enables language models to develop agentic capabilities from scratch without expensive annotated datasets or dependence on closed-source models like GPT-4. While most agent frameworks require either extensive human-labeled training data or access to proprietary models for learning, AutoAct addresses both constraints simultaneously through a self-planning approach. Developed as an ACL 2024 research project, the framework introduces a division-of-labor strategy where a single Meta-Agent automatically differentiates into specialized sub-agents for planning, tool usage, and reflection based on target task requirements. This architecture eliminates the traditional bottleneck of collecting high-quality agent trajectories, instead generating its own training data through self-instruction techniques. AutoAct demonstrates that effective agent systems can emerge from relatively modest foundations, requiring only a tool library and a base language model. The framework has proven competitive with stronger baselines across benchmarks like HotpotQA and ScienceQA while maintaining data independence, making it particularly valuable for research teams and organizations unable to access premium AI models or afford large-scale data annotation efforts.

How It Works

AutoAct operates through a two-stage process that bootstraps agent capabilities from minimal initial resources. In the first stage, the framework amplifies task data independently using self-instruction techniques, where the Meta-Agent generates diverse task scenarios, potential approaches, and expected outcomes without human supervision. This self-synthesis creates the training foundation without requiring expensive annotated datasets. In the second stage, AutoAct employs a division-of-labor strategy to differentiate the Meta-Agent into specialized sub-agents based on target task characteristics. Rather than using a single generalist model for all agent functions, the system creates dedicated plan agents that generate multi-step strategies, tool agents that select and execute appropriate functions from the tool library, and reflection agents that evaluate outcomes and adjust approaches. These specialized agents collaborate on task completion, with the Meta-Agent coordinating their interactions. The self-planning process occurs automatically as the Meta-Agent generates planning trajectories without human intervention, learning to decompose complex tasks, sequence tool usage, and recover from failures through experience rather than explicit programming.

Core Features

• •

  Data Independence eliminates the expensive annotated dataset requirement that constrains most agent learning systems. AutoAct generates its own training data through self-instruction techniques where the Meta-Agent creates task scenarios and learning trajectories autonomously, making agent development accessible to teams without resources for large-scale human annotation efforts.

• •

  Self-Synthesis Process enables the framework to amplify task data internally rather than depending on external sources. The Meta-Agent generates diverse task variations, explores alternative approaches, and creates its own learning examples, building a rich training foundation from minimal initial resources and adapting to new domains without starting from scratch.

• •

  Division-of-Labor Strategy automatically differentiates the Meta-Agent into specialized sub-agents optimized for specific functions. Rather than forcing a single model to handle planning, tool usage, and reflection simultaneously, AutoAct creates dedicated agents for each responsibility, improving performance through focused specialization while maintaining coordination across the agent system.

• •

  Meta-Agent Architecture provides a foundational model that orchestrates the entire agent system while serving as the source for specialized sub-agents. The Meta-Agent handles high-level coordination, generates self-instruction data, and spawns specialized agents as needed, creating a scalable architecture where capability expansion doesn't require retraining the entire system.

• •

  Self-Planning Process generates planning trajectories automatically without human demonstration or access to proprietary models. The Meta-Agent learns to decompose complex tasks into subtasks, sequence tool usage appropriately, handle dependencies between steps, and adapt plans when encountering obstacles, developing planning capabilities through experience rather than imitation.

• •

  Model Agnostic Design works with various open-source language models rather than depending on closed-source options like GPT-4. Organizations can use models they have access to or can run locally, maintaining independence from commercial AI providers while still achieving competitive agent performance on benchmark tasks.

Who This Is For

AutoAct serves research teams and organizations facing constraints around data annotation resources or access to premium AI models. It's particularly valuable for academic researchers studying agent learning mechanisms who need reproducible systems without expensive dependencies, and for companies in regulated industries or regions where GPT-4 and similar closed-source models aren't viable options. Teams building specialized agents for niche domains benefit from AutoAct's self-synthesis capabilities, which generate training data adapted to specific task distributions rather than relying on generic annotated datasets. Organizations with compute resources but limited annotation budgets can leverage AutoAct's data independence to develop capable agents through automated learning rather than human labeling. The framework also suits teams prioritizing model transparency and control over raw performance, as using open-source base models provides full visibility into agent behavior. However, organizations with access to GPT-4, ample annotation resources, and preference for maximum performance over independence may find specialized commercial agent platforms more immediately effective for production applications.
