🎯 Project Background

Business Challenges

In the process of implementing enterprise AI applications, we face the following core challenges:

1. High Inference Costs: LLM inference costs account for 60%-80% of the total AI application cost, severely restricting large-scale adoption.
2. Prominent Performance Bottlenecks: High inference latency (P95 > 5s) makes it difficult to meet real-time interaction demands.
3. Low Development Efficiency: Building an Agent from 0 to 1 takes 3-6 months due to a lack of standardized frameworks.
4. Data Security Risks: Risks of sensitive data (PII) leakage and a lack of privacy protection mechanisms.
5. Difficulty in Continuous Optimization: Lack of a feedback loop makes it impossible to continuously improve model performance.

Solutions

OpenEAAP (Open Enterprise AI Agent Platform) is an enterprise-grade AI Agent platform designed to solve the above pain points:

🚀 Quick Start

Prerequisites

• Go 1.24 or higher
• Docker and Docker Compose (for local development)
• Kubernetes 1.25+ (for production deployment)
• PostgreSQL 14+, Redis 7+, Milvus 2.3+ (can be started quickly via Docker Compose)

Local Development Environment Setup

1. Clone the Repository

git clone [https://github.com/openeeap/openeeap.git](https://github.com/openeeap/openeeap.git)
cd openeeap

2. Start Dependent Services

Use Docker Compose to quickly start dependent services like PostgreSQL, Redis, Milvus, and MinIO:

docker-compose up -d

3. Initialize Database

Run the database migration script to create table structures:

make migrate-up

4. Configure Environment Variables

Copy the configuration file template and modify it according to your actual environment:

cp configs/development.yaml.example configs/development.yaml
# Edit configs/development.yaml to configure DB connection, Redis, Milvus, etc.

5. Start Services

# Start HTTP Service
make run-server

# Or run directly using Go command
go run cmd/server/main.go --config configs/development.yaml

After the service starts, you can access it via the following addresses:

• HTTP API: http://localhost:8080
• gRPC API: localhost:9090
• Swagger UI: http://localhost:8080/swagger/index.html

6. Run Tests

# Run all tests
make test

# Run unit tests
make test-unit

# Run integration tests
make test-integration

# View test coverage
make test-coverage

💡 Usage Examples

Example 1: Create a Simple Agent

Create a GPT-4 based Customer Service Agent via HTTP API:

curl -X POST http://localhost:8080/api/v1/agents \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Customer Support Agent",
    "description": "Automatically answers common customer questions",
    "runtime_type": "native",
    "config": {
      "model": "gpt-4",
      "temperature": 0.7,
      "max_tokens": 500,
      "system_prompt": "You are a professional customer support assistant responsible for answering customer questions about the product."
    }
  }'

Response Example:

{
  "id": "agent-123456",
  "name": "Customer Support Agent",
  "status": "active",
  "created_at": "2026-01-15T10:30:00Z"
}

Example 2: Execute Agent Task

Send a request to the Agent to get an intelligent response:

curl -X POST http://localhost:8080/api/v1/agents/agent-123456/execute \
  -H "Content-Type: application/json" \
  -d '{
    "input": "What payment methods does your product support?",
    "context": {
      "user_id": "user-789",
      "session_id": "session-abc"
    }
  }'

Response Example:

{
  "output": "We support the following payment methods: 1. Alipay 2. WeChat Pay 3. Credit Cards (Visa, MasterCard) 4. Bank Transfer. You can choose the most convenient method at checkout.",
  "execution_time_ms": 1200,
  "cached": false,
  "trace_id": "trace-xyz789"
}

Example 3: Create Workflow

Define a multi-step Workflow (e.g., Document Analysis Flow):

# workflow.yaml
name: Document Analysis Workflow
description: Automatically analyze uploaded contract documents and extract key information
steps:
  - id: step1
    name: Document Parsing
    agent: document-parser
    input: "${workflow.input.document_url}"
  
  - id: step2
    name: Information Extraction
    agent: info-extractor
    input: "${step1.output.text}"
    depends_on:
      - step1
  
  - id: step3
    name: Risk Assessment
    agent: risk-analyzer
    input: "${step2.output.entities}"
    depends_on:
      - step2

trigger:
  type: manual

Create Workflow via CLI:

openeeap workflow create -f workflow.yaml

Run Workflow:

openeeap workflow run document-analysis-workflow \
  --input '{"document_url": "[https://example.com/contract.pdf](https://example.com/contract.pdf)"}'
