Esperanto is a powerful Python library that provides a unified interface for interacting with various Large Language Model (LLM) providers. It simplifies the process of working with different AI models (LLMs, Embedders, Transcribers, and TTS) APIs by offering a consistent interface while maintaining provider-specific optimizations.

Why Esperanto? 🚀

**🪶 Ultra-Lightweight Architecture**

• Direct HTTP Communication: All providers communicate directly via HTTP APIs using httpx - no bulky vendor SDKs required
• Minimal Dependencies: Unlike LangChain and similar frameworks, Esperanto has a tiny footprint with zero overhead layers
• Production-Ready Performance: Direct API calls mean faster response times and lower memory usage

**🔄 True Provider Flexibility**

• Standardized Responses: Switch between any provider (OpenAI ↔ Anthropic ↔ Google ↔ etc.) without changing a single line of code
• Consistent Interface: Same methods, same response objects, same patterns across all 15+ providers
• Future-Proof: Add new providers or change existing ones without refactoring your application

**⚡ Perfect for Production**

• Prototyping to Production: Start experimenting and deploy the same code to production
• No Vendor Lock-in: Test different providers, optimize costs, and maintain flexibility
• Enterprise-Ready: Direct HTTP calls, standardized error handling, and comprehensive async support
