VLLM Swarm Agents¶

Quick Summary

This guide demonstrates how to create a sophisticated multi-agent system using VLLM and Swarms for comprehensive stock market analysis. You'll learn how to configure and orchestrate multiple AI agents working together to provide deep market insights.

Overview¶

The example showcases how to build a stock analysis system with 5 specialized agents:

Technical Analysis Agent
Fundamental Analysis Agent
Market Sentiment Agent
Quantitative Strategy Agent
Portfolio Strategy Agent

Each agent has specific expertise and works collaboratively through a concurrent workflow.

Prerequisites¶

Requirements

Before starting, ensure you have:

Python 3.7 or higher
The Swarms package installed
Access to VLLM compatible models
Sufficient compute resources for running VLLM

Installation¶

Setup Steps

Install the Swarms package:
```
pip install swarms
```
Install VLLM dependencies (if not already installed):
```
pip install vllm
```

Basic Usage¶

Here's a complete example of setting up the stock analysis swarm:

from swarms import Agent, ConcurrentWorkflow
from swarms.utils.vllm_wrapper import VLLMWrapper

# Initialize the VLLM wrapper
vllm = VLLMWrapper(
    model_name="meta-llama/Llama-2-7b-chat-hf",
    system_prompt="You are a helpful assistant.",
)

Model Selection

The example uses Llama-2-7b-chat, but you can use any VLLM-compatible model. Make sure you have the necessary permissions and resources to run your chosen model.

Running the Swarm¶

To execute the swarm analysis:

swarm = ConcurrentWorkflow(
    name="Stock-Analysis-Swarm",
    description="A swarm of agents that analyze stocks and provide comprehensive analysis.",
    agents=stock_analysis_agents,
)

# Run the analysis
response = swarm.run("Analyze the best etfs for gold and other similar commodities in volatile markets")

Performance
- Problem: Slow response times
- Solution: Use proper batching and optimize model loading

FAQ¶

Can I use different models for different agents?

Yes, you can initialize multiple VLLM wrappers with different models for each agent. However, be mindful of memory usage.

How many agents can run concurrently?

The number depends on your hardware resources. Start with 3-5 agents and scale based on performance.
