Agentic AI Terminology Explained: Frameworks, Workflows, Studios, and More

What Makes an AI System "Agentic"?

The majority of traditional AI systems have been reactive tools that produce preset outputs in response to particular inputs. On the other hand, when AI actively interacts with its surroundings, making its choices based on predetermined objectives, and acts with little human guidance, just like someone with autonomy, this is the phase where that AI becomes an agent. 

Three core characteristics can define an AI agent:

• Autonomy: The ability to operate independently
• Goal-directed behaviour: Working toward specific objectives
• Environmental interaction: Engaging with and manipulating its surroundings

The development of agentic systems has been expedited by the emergence of large language models (LLMs), which offer a versatile agentic AI framework for planning, reasoning, and natural language comprehension.

Foundational Terminology

Before discussing frameworks and architectures, it is important to make clear several basic differences:

• Agents vs. Models
  Claude or GPT-4 are examples of language models that are not necessarily agents. When a model is integrated into a system that can act on the model's outputs, it turns into an agent. The "thinking" is provided by the model, and the "doing" is provided by the agent framework.
• Task Planning vs. Execution
  While execution entails carrying out the measures that have been decided upon, planning entails deciding what steps to take. Advanced agents manage both, first deciding how to tackle an issue and then taking the appropriate action.
• Tools and Tool Use
  Tools are external functions that agents can use to carry out particular activities, such as running code, conducting online searches, or gaining access to specialised APIS. One important metric of an agent's capacity is its ability to choose and employ tools effectively.
• Reasoning Capabilities
  This is a reference to the way agents solve issues, make decisions, and process information. The ways in which different agent designs apply reasoning vary, ranging from straightforward prompt templates to intricate multi-step thought processes.

Popular Agentic AI Frameworks

In recent years, the agent framework ecosystem has grown significantly. Some of the most significant are as follows:

• LangChain
  By offering a modular architecture for creating agents with reasoning, tool access, and memory management capabilities, LangChain is arguably the most popular framework. Flexible agent construction across a range of use cases is made possible by its component-based methodology.
• AutoGPT
  AutoGPT, one of the first widely recognized autonomous agent systems, is designed to do long-term, goal-oriented tasks with little assistance from humans. It uses a self-prompting loop to enable ongoing operation in the direction of predetermined goals. 
• Semantic Kernel
  The focus of Microsoft's Semantic Kernel, their contribution to the agent ecosystem, is on integrating with current software engineering methodologies. It serves as a link between natural language support and conventional programming.
• BabyAGI
  Through recursive task creation and prioritization, BabyAGI, a simplified agent architecture centred on task management, shows how even simple agent designs may achieve complicated objectives.
• CrewAI
  By using a multi-agent strategy, CrewAI makes it possible to form specialized agent teams with clear roles and patterns of cooperation. In order to handle complex tasks, this framework mimics human organizational systems.

Although the flexibility, usability, and ideal use cases of these frameworks vary, they all offer architecture for transforming language models into agents with a purpose. 

Agent Architectures

Several architectural models for organising agent behaviour and reasoning have surfaced, going beyond particular frameworks:

• ReAct (Reasoning and Acting)
  Agents can reason about what they have seen, act on that reasoning, and then continuously observe the results thanks to this design, which interleaves thinking and action processes. ReAct works especially well for complicated, multi-step processes. 
• Plan-and-Solve
  This method involves agents creating a detailed plan before taking any action. When there is a requirement for flexibility, this architecture may not perform as well as it does in situations that call for a great deal of planning.
• Reflexion
  Self-reflection capabilities allow Reflexion agents to assess their performance and modify their tactics as necessary. This metacognitive method makes continual, experience-based development possible.
• Multi-agent systems
  Instead of depending on a single agent, these systems use specialized agents that work together to achieve common objectives. The division of labor enables more robust problem-solving and competence in specific disciplines.

Every architecture represents distinct trade-offs between relevant use cases, efficiency, and complexity. 

Agent Development Environments

There are now specialized development environments as agent technology advances. We will discuss a few of them:

• AI Agent Studios
  For the development, testing, and deployment of agents, platforms such as Fixie, Langchain Hub, and Superagent offer integrated environments. These studios lower the technical barriers to entry by frequently using visual interfaces for agent building.
• No-code/Low-code Agent Builders
  Through visual programming interfaces, tools like FlowiseAI and LangFlow let non-developers build agent processes using simple drag-and-drop interfaces.
• IDE Integrations
  Development environment extensions, such as VS Code, allow AI support within well-known developer tools by integrating agent capabilities straight into coding workflows.

Regarding who should be permitted to construct agents and how the development process should be organized, these environments reflect different viewpoints.

How do Workflows Work in Agentic AI Systems?

Workflows in Agentic AI Systems

Workflows in agentic systems are structured sequences of tasks that guide these autonomous AI agents to complete specific goals. They define the steps an agent should take, decision points, and success criteria. Workflows combine planning capabilities with execution, allowing agents to decompose complex problems, prioritize subtasks, and adapt to unexpected scenarios. They typically include perception (understanding the environment), reasoning (analyzing options), planning (mapping steps to achieve goals), and action (executing decisions). Well-designed workflows balance autonomy with guardrails, enabling agents to solve problems independently while remaining aligned with human intentions.

AI Agent Workflows

Internal processes that guide agent behaviour can be arranged in a variety of ways.

• Prompt-based Workflows
  The most straightforward method, wherein meticulously designed prompts predominantly direct agent behavior. This method, however simplistic, provides clarity and consistency.
• Chain-of-thought Workflows
  These workflows explicitly represent the reasoning process, breaking down difficult problems into intermediate parts. This strategy improves agent performance on tasks that require logical reasoning or multi-step planning.
• Function-calling Patterns
  These workflows are built around the agent's capacity to call particular functions and use defined tool interfaces to constrain and direct agent actions. This gives you more control and predictability than open-ended text generation.
• RAG-enabled Agents
  Using Retrieval Augmented Generation (RAG), these agents may access and exploit external knowledge bases, greatly boosting their effective knowledge without the need for larger underlying models.

The workflow decision has a considerable impact on an agent's capabilities, limits, and acceptable applications.

Evaluation and Benchmarking

Methodological approaches to agent evaluation have emerged as the area has progressed, including the following: 

AgentBench and Similar Frameworks

The agents are tested in these standardized evaluation environments across a variety of aspects, including their ability to reason, their proficiency in using tools, and their alignment with their goals.

Key Metrics

Agent evaluation typically considers multiple factors:

• Task completion rate
• Efficiency (steps or tokens required)
• Adherence to constraints
• Robustness to unexpected situations

Safety and Alignment Evaluation

Increasingly, agents are evaluated not just on their functional effectiveness but also on their compatibility with human values, their resistance to misuse, and their ability to avoid destructive behaviors.

Due to the open-ended nature of agent tasks and the complexity of defining "success" in many contexts, rigorous evaluation continues to be a tricky endeavour.

Real-world Applications

The application of agent-based artificial intelligence is already being utilized in a variety of fields: 

• Code Generation and Development
  It is possible to get assistance with coding tasks from agents such as GitHub Copilot and Amazon CodeWhisperer. These agents also suggest completions and generate implementations based on natural language descriptions.
• Research Assistants
  Elicit and Consensus are two examples of tools that assist researchers in exploring the literature, summarizing findings, and identifying linkages between different studies.
• Customer Service Agents
  Businesses are now deploying conversational agents. These agents are able to manage consumer inquiries, process requests, and escalate complex situations to human representatives.
• Data Analysis Agents
  In response to natural language queries, data may be analyzed, visualizations can be generated, and insights can be extracted using applications like Google Sheets and Microsoft Copilot for Excel.

Additionally, these applications illustrate the significance of human-AI collaboration while demonstrating the practical benefit of agentic systems.
