Architecture Overview

​

System Components

​

Core Components

​

Agents

• AI-powered entities backed by large language models (LLMs)
• Execute tasks and interact with users
• Maintain persistent state and memory
• Can be extended with tools and integrations

​

Sessions

• Stateful interactions between agents and users
• Maintain context across multiple exchanges
• Support long-running conversations
• Handle context management automatically

​

Tasks

• Multi-step, programmatic workflows
• Support various step types:
  • Prompts and LLM interactions
  • Tool calls and integrations
  • Conditional logic and loops
  • Parallel execution

​

Tools

Four types of tool integrations:

1. User-defined Functions

   • Custom function signatures
   • Client-side execution
   • Flexible implementation

2. System Tools

   • Built-in platform capabilities
   • Direct access to Julep APIs
   • Automatic execution

3. Built-in Integrations

   • Pre-configured third-party tools
   • Server-side execution
   • Managed authentication

4. Direct API Calls

   • HTTP/REST endpoints
   • Custom API integration
   • Runtime parameter support

​

Infrastructure Components

​

Document Store

• Vector database for semantic search
• Document management system
• Support for various file types
• Automatic indexing and retrieval

​

Task Execution Engine

• Distributed task processing
• State management
• Error handling and retries
• Parallel execution support

​

API Layer

• RESTful API endpoints
• SDK support
• Authentication and authorization
• Rate limiting and quotas

​

Data Flow

1. Client Interaction

   • SDK or API calls initiate requests
   • Authentication and validation
   • Request routing

2. Task Processing

   • Task decomposition
   • Step execution
   • State management
   • Tool integration

3. Response Handling

   • Result aggregation
   • Error handling
   • Client notification
   • State persistence

​

Security Architecture

​

Authentication

• API key-based access
• Role-based permissions
• Session management
• Token validation

​

Data Protection

• Encryption at rest
• Secure communication
• Data isolation
• Access controls

​

Monitoring

• Audit logging
• Performance metrics
• Error tracking
• Usage analytics
