I got tired of switching AI SDKs every time I wanted to try a new model

Short summary

Developer spent a weekend refactoring code when switching from OpenAI to Anthropic due to incompatible SDKs, auth mechanisms, and response formats. Solution: build a unified abstraction layer using Python's abstract base class pattern, allowing provider swaps with minimal code changes. Works well for simple tasks; advanced features like streaming and tool use still require provider-specific implementations.

• •Different AI provider SDKs require completely different implementations (authentication, method calls, response handling)
• •Abstract base class pattern allows swapping providers via configuration without rewriting application code
• •Works well for simple tasks; advanced features like streaming and tool use still require provider-specific handling

Generated with AI, which can make mistakes.
