Prerequisites

1

Install Package

First, install PraisonAI Agents:

pip install "praisonaiagents[llm]"

praisonaiagents[llm] includes all Google Gemini dependencies. For No-Code implementation, also install: pip install langchain-google-genai

2

Set API Key

Set your Gemini API key:

export GEMINI_API_KEY=xxxxxxxxxxx
3

Code

from praisonaiagents import Agent

agent = Agent(
    instructions="You are a helpful assistant",
    llm="gemini/gemini-1.5-flash-8b",
    self_reflect=True,
    verbose=True
)

agent.start("Why sky is Blue?")

​
Code Implementation

​
Basic Usage

The simplest way to use Gemini with PraisonAI Agents:

from praisonaiagents import Agent

agent = Agent(
    instructions="You are a helpful assistant",
    llm="gemini/gemini-1.5-flash-8b",
    self_reflect=True,
    verbose=True
)

agent.start("Why sky is Blue?")

​
Multi-Agent Setup

Create multiple agents working together:

from praisonaiagents import Agent, Task, PraisonAIAgents

agent = Agent(
    instructions="You are a helpful assistant",
    llm="gemini/gemini-1.5-flash-8b",
    self_reflect=True,
    verbose=True
)

task = Task(
    description="Why sky is Blue?",
    agent=agent,
)

agents = PraisonAIAgents(
  agents=[agent],
  tasks=[task],
)

agents.start()

This uses Litellm to connect to Google Gemini.
