Struct OpenAIProvider 

pub struct OpenAIProvider { /* private fields */ }

OpenAI LLM provider using the Chat Completions API.

Also supports OpenAI-compatible APIs (Ollama, vLLM, Azure OpenAI, etc.) via the with_base_url constructor.

Implementations

impl OpenAIProvider

pub fn new(api_key: String, model: String) -> Self
