 The library follows the OpenAI client API design pattern, making it familiar to developers already using OpenAI and enabling easy migration for existing applications. **Simply change your import statements and instantly gain access to hundreds of models** across dozens of providers while maintaining your existing code structure.
 
-With support for 19 implemented providers (and more planned), OneLLM gives you access to approximately 300+ unique language models through a single, consistent interface - from the latest proprietary models to open-source alternatives, all accessible through familiar OpenAI-compatible patterns.
