I stopped hardcoding AI API calls. It creates a maintenance nightmare.

I started with OpenAI. Then a client wanted Claude. I had one function for OpenAI. Adding another provider meant copying code.

I tried environment variables. The code became a mess of if-else blocks. I needed a common interface.

I built an abstraction layer. I used the Strategy pattern.

It works like this:

  • Create a base class for providers.
  • Write a specific class for each API.
  • Let the app call the base class.

Your app ignores which backend runs.

Benefits:

  • Add new providers easily.
  • Test with mock providers.

Downsides:

  • It is overkill for one provider.
  • You lose unique API features.
  • Error mapping takes work.

My advice: Start with one concrete provider. Refactor when you add a second one.

This saved me from a full rewrite.

How do you handle multiple AI providers?
