🤖 Understanding the Role of Agents in Multi-Step Tasks
🧩 What Are Agents?
Agents are intelligent orchestrators that manage multi-step tasks by coordinating between:
- Foundation Models (LLMs)
- APIs
- External data sources (e.g., databases, knowledge bases)
- User inputs
They go beyond simple prompt-response interactions by understanding user intent, breaking it into sub-tasks, and performing actions to fulfill complex workflows.
🔄 Why Agents?
Foundation models (LLMs) are good at generating text or answering questions—but they cannot:
- Interact with APIs
- Retrieve real-time organizational data
- Make decisions based on current state or workflows
Agents bridge that gap by:
- Decomposing user requests into steps
- Calling APIs or retrieving knowledge
- Combining logic + LLM output to complete tasks
🧠 Agents for Amazon Bedrock – What It Does
Agents for Amazon Bedrock is a fully managed service that allows developers to:
- Build task-oriented assistants powered by LLMs
- Connect foundation models with real-time business systems
- Automate complex processes without retraining models
🏗️ How It Works (Step-by-Step)
- User Input (e.g., “Book me a scuba diving trip in Phuket next weekend.”)
- Agent Invocation:
The agent understands the intent and breaks it into steps:- Check available dates
- Find packages
- Collect preferences
- Process booking via API
- Foundation Model Guidance:
LLM interprets natural language and helps formulate intermediate questions or responses. - API Integration:
The agent securely calls external APIs or databases to complete actions. - Knowledge Base Augmentation:
The agent retrieves context from Amazon Bedrock’s knowledge base if needed. - Response Generation:
A final, context-aware response is returned to the user.
