Gochestra

Gochestra is a small Go library that wraps multiple LLM providers behind a single Agent interface. It lets you swap providers and models quickly while keeping the same invocation shape.

Features

• Unified Agent interface for chat-style calls.
• Providers: OpenAI, Anthropic, Gemini, Groq.
• Simple, stateless Invoke API.

Install

go get github.com/alokxcode/gochestra

Quick Start

package main

import (
	"context"
	"fmt"

	"github.com/alokxcode/gochestra/agent"
)

func main() {
	ag := agent.New(agent.OpenAi, "YOUR_API_KEY")

	cfg := &agent.ChatConfig{
		Model:        "gpt-4o-mini",
		SystemPrompt: "You are a helpful assistant.",
		MaxToken:     200,
	}

	prompt := agent.Prompt{Text: "Say hello in one sentence."}

	res, err := ag.Invoke(prompt, nil, cfg, context.Background())
	if err != nil {
		panic(err)
	}

	fmt.Println(res.Content.Openai.Choices[0].Message.Content)
}

Providers

Use the agent.Provider constants when creating an agent:

• agent.OpenAi
• agent.Anthropic
• agent.Gemini
• agent.Groq

Each provider requires a valid API key. You pass it directly to agent.New.

Configuration

agent.ChatConfig controls the request:

• Model - provider-specific model name
• SystemPrompt - system message sent before user content
• MaxToken - max output tokens

Notes

• The library is intentionally minimal and stateless.
