Grant Miller, a Distinguished Engineer at IBM, recently illuminated the intricate realm of AI agents, addressing pivotal considerations surrounding their development and deployment.
In a recent presentation, Miller delineated the present trajectory of AI agents, underscoring the imperative for meticulous oversight and comprehension of their functionalities.
He highlighted a significant evolution: the transition from agents executing singular, predetermined tasks to more advanced entities capable of collaborating, reasoning, and adapting to realize intricate objectives.
The crux of Miller’s argument rests on the premise that, despite the remarkable progress in the abilities and versatility of AI agents, their evolution must adhere to principles that guarantee safety, predictability, and alignment with human interests.
He juxtaposed the sensationalized Hollywood portrayal of omnipotent AI agents with the more pragmatic reality of creating functional and dependable systems.
Understanding AI Agent Agency
Miller commenced by expounding the prevalent notion of AI agents as all-powerful entities capable of executing any task. However, he rapidly transitioned to a more grounded viewpoint, elucidating that the genuine challenge resides in defining and managing the agency of these systems.
He articulated a dichotomy: agents may possess insufficient agency, rendering them mere tools, or conversely, excessive agency, leading to unforeseen and potentially adverse outcomes.

The essence of Miller’s discourse is that the design approach for agents should concentrate on minimizing two pivotal factors: super-agency and over-privilege.
Super agency pertains to an agent’s ability to undertake any action deemed necessary to fulfill its objectives, irrespective of its original programming or human oversight.
In contrast, over-privilege relates to the breadth of access and permissions allotted to an agent, which can exacerbate the ramifications of its actions.
“We don’t want a super agency,” Miller articulated, stressing that agents should not possess the autonomy to independently determine and execute actions they believe will satisfy their goals.
This underscores the pitfalls of the “one size fits all” paradigm; a singular approach to agency proves inadequate for the diverse spectrum of tasks and threats associated with AI agents.
The Risk-Capability Matrix
To facilitate a more coherent understanding and management of AI agents’ evolution, Miller introduced a thought-provoking framework: a 2×2 matrix juxtaposing capability against risk. This matrix serves to categorize varying agent behaviors and design considerations:
- Low Capability, Low Risk: These are simplistic, rule-based agents with narrow scope and negligible potential for adverse outcomes, executing well-defined tasks with predictable results.
- Low Capability, High Risk: This quadrant encompasses agents that, while not highly capable, still pose risks due to their access or contextual environment. An example includes an agent with broad access to sensitive information yet limited contextual comprehension.
- High Capability, Low Risk: Agents in this category are exceptionally proficient, capable of executing complex tasks, yet their actions remain constrained, substantially diminishing the likelihood of harm. This state is optimal for various applications.
- High Capability, High Risk: Many advanced AI agents currently operate within this quadrant, exhibiting significant capabilities but also incurring elevated risks due to their autonomous nature and potential for unforeseen actions.
Miller proposed that the objective for numerous applications should be to gravitate toward the “High Capability, Low Risk” quadrant. This entails designing agents that are both potent and secure, adept at handling intricate tasks without introducing undue risk.
Desired Agent Behaviors
Miller delineated the sought-after characteristics of effective AI agents, framing them within a balance of what should be avoided versus what should be desired:
- Avoid: Super agency and over-privilege.
- Desire: Minimization of actions, restricted access, and high cohesion.
He further elucidated these elements:
- Minimized Actions: Agents should execute only the essential actions required to meet their objectives, steering clear of unnecessary or unprompted behaviors.
- Minimized Access: Agents must only be granted access to the data and systems pertinent to their designated tasks, adhering to the principle of least privilege.
- High Cohesion & Collaboration: Agents should function effectively alongside other agents and systems, operating in a harmonized and coherent manner to achieve broader objectives. This necessity entails robust communication and inter-agent coordination strategies.
The notion of “one size fits all” is counterproductive, as it neglects the diverse levels of risk and capability inherent in various applications. Instead, a bespoke approach is imperative, wherein each agent’s agency and access are scrupulously defined according to its specific function and operational context.
The Future of AI Agents
Miller concluded by accentuating the ongoing transformation of AI agents and the significance of a methodical approach to their development.
He asserted that through a comprehensive understanding of the relationship between capability and risk, and by concentrating on minimizing adverse attributes such as super-agency and over-privilege, developers can forge agents that are not only powerful but also dependable and secure.
The ultimate aspiration is to cultivate agents capable of effective collaboration, functioning within delineated parameters, and positively impacting human endeavors.
