Advances and challenges in Foundation Agents
FROM BRAIN-INSPIRED INTELLIGENCE TO EVOLUTIONARY, COLLABORATIVE, AND SAFE SYSTEMS
A massive paper just landed today! A group of researchers from 20 universities and AI labs (incl. Stanford University, Yale University, CIFAR, Google DeepMind, Microsoft Research, MetaGPT and many more) released a 264-page technical survey (or should I say book?) on the next evolution of LLMs. It’s what they call “𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻 𝗔𝗴𝗲𝗻𝘁𝘀.”

Definition of Foundation Agent
A Foundation Agent is an autonomous, adaptive intelligent system designed to actively perceive diverse signals from its environment, continuously learn from experiences to refine and update structured internal states (such as memory, world models, goals, emotional states, and reward signals), and reason about purposeful actions—both external and internal—to autonomously navigate toward complex, evolving objectives.
More concretely, a Foundation Agent possesses the following core capabilities:
- Active and Multimodal Perception: It continuously and selectively perceives environmental data from multiple modalities (textual, visual, embodied, or virtual).
- Dynamic Cognitive Adaptation: It maintains and autonomously optimizes a rich internal mental state (memory, goals, emotional states, reward mechanisms, and comprehensive world models) through learning that integrates new observations and experiences.
- Autonomous Reasoning and Goal-Directed Planning: It proactively engages in sophisticated reasoning processes, including long-term planning and decision-making, to drive goal-aligned strategies.
- Purposeful Action Generation: It autonomously generates and executes purposeful actions, which can be external (physical movements, digital interaction, communication with other agents or humans) or internal (reflection, reasoning, self-reflection, optimization) or creative structures, systematically shaping its environment and future cognition to fulfil complex objectives.
- Collaborative Multi-Agent Structure: It can operate within multi-agent or agent society structures, coordinating through shared communication and collective reasoning to accomplish complex tasks and goals beyond individual capabilities.
The definition blends three essential pillars distinguishing Foundation Agents:
- sustained autonomy (operating independently toward long-term goals without step-by-step human intervention),
- adaptive learning (evolving internal representations continually over diverse experiences),
- and purposeful reasoning (generating actions that provide minimal sufficient control of the world).
Foundation Agents represent a fundamental shift from traditional agents by integrating deep cognitive structures, multimodal processing capabilities, and advanced reasoning systems—enabling them to function competently across a wide range of environments and domains.
