Learn how to design a flexible architecture for integrating multiple LLMs using a single Go interface

intermediate Published 25 Jun 2026

Action Steps

Define a Provider interface in Go to abstract away LLM-specific details
Implement the Provider interface for each LLM, such as Claude, GPT, and Gemini
Use a factory function to create instances of the Provider interface for each LLM
Configure the transport classes to communicate with the LLMs
Test the integration with multiple LLMs using the single Provider interface

Who Needs to Know This

This article is relevant for software engineers, particularly those working with Go and LLMs, as it provides insights into designing a scalable architecture for integrating multiple LLMs.

Key Insight

💡 A well-designed interface can abstract away the complexities of integrating multiple LLMs, making it easier to add or remove providers
