Abstracting Seven LLM APIs Into a Single Streaming Contract

This approach solves a critical pain point in the AI developer experience: managing inconsistent APIs across multiple LLM providers. By abstracting each provider's streaming format into a unified contract, developers can support OpenAI, Claude, Gemini, and beyond without duplicating parsing logic on the client side. This pattern demonstrates how thoughtful API design can dramatically simplify multi-provider applications while maintaining user control over their API keys.
