Overview

GoFlow supports multiple Large Language Model providers out of the box.

GoFlow provides a unified interface for working with various Large Language Models (LLMs). You can easily switch between providers or use multiple providers simultaneously within the same agent or workflow.

Supported Providers

Configuration

Set your API keys before running your application. You can set these in your environment variables or in your .env file.

# OpenAI
export OPENAI_API_KEY="sk-..."
 
# Anthropic
export ANTHROPIC_API_KEY="sk-ant-..."
 
# Google Gemini (either works)
export GOOGLE_API_KEY="AIza..."
export GEMINI_API_KEY="AIza..."

Quick Start

Initialize a provider and start using it immediately:

import (
    "github.com/nuulab/goflow/pkg/llm/openai"
    "github.com/nuulab/goflow/pkg/llm/anthropic"
    "github.com/nuulab/goflow/pkg/llm/gemini"
)
 
func main() {
    // OpenAI - reads OPENAI_API_KEY from env
    llm1 := openai.New("")
 
    // Anthropic Claude - reads ANTHROPIC_API_KEY from env
    llm2 := anthropic.New("")
 
    // Google Gemini - reads GOOGLE_API_KEY from env
    llm3 := gemini.New("")
}

Using with Agents

Pass the initialized LLM to an agent:

import (
    "github.com/nuulab/goflow/pkg/agent"
    "github.com/nuulab/goflow/pkg/llm/openai"
    "github.com/nuulab/goflow/pkg/tools"
)
 
// Create LLM
llm := openai.New("")
 
// Create agent with LLM
myAgent := agent.New(llm, tools.BuiltinTools(),
    agent.WithMaxIterations(10),
    agent.WithSystemPrompt("You are a helpful coding assistant."),
)
 
// Run task
result, err := myAgent.Run(ctx, "Write a function to reverse a string in Go")
fmt.Println(result.Output)
