 ## 2. Provider-Agnostic via LiteLLM
 
+You can use LlmConfig, to quickly configure multiple variations of LLMs and experiment with them to find the optimal one for your use case. You can read more about LlmConfig [here](/api/parameters).

+llmConfig = LlmConfig(provider="openai/gpt-4o-mini", api_token=os.getenv("OPENAI_API_KEY"))

 Crawl4AI uses a “provider string” (e.g., `"openai/gpt-4o"`, `"ollama/llama2.0"`, `"aws/titan"`) to identify your LLM. **Any** model that LiteLLM supports is fair game. You just provide:
 
 - **`provider`**: The `<provider>/<model_name>` identifier (e.g., `"openai/gpt-4"`, `"ollama/llama2"`, `"huggingface/google-flan"`, etc.).  
 - **`api_token`**: If needed (for OpenAI, HuggingFace, etc.); local models or Ollama might not require it.  
-- **`api_base`** (optional): If your provider has a custom endpoint.  
+- **`base_url`** (optional): If your provider has a custom endpoint.  
 
 This means you **aren’t locked** into a single LLM vendor. Switch or experiment easily.

 Below is an overview of important LLM extraction parameters. All are typically set inside `LLMExtractionStrategy(...)`. You then put that strategy in your `CrawlerRunConfig(..., extraction_strategy=...)`.
 
-1. **`provider`** (str): e.g., `"openai/gpt-4"`, `"ollama/llama2"`.  
-2. **`api_token`** (str): The API key or token for that model. May not be needed for local models.  
-3. **`schema`** (dict): A JSON schema describing the fields you want. Usually generated by `YourModel.model_json_schema()`.  
-4. **`extraction_type`** (str): `"schema"` or `"block"`.  
-5. **`instruction`** (str): Prompt text telling the LLM what you want extracted. E.g., “Extract these fields as a JSON array.”  
-6. **`chunk_token_threshold`** (int): Maximum tokens per chunk. If your content is huge, you can break it up for the LLM.  
-7. **`overlap_rate`** (float): Overlap ratio between adjacent chunks. E.g., `0.1` means 10% of each chunk is repeated to preserve context continuity.  
-8. **`apply_chunking`** (bool): Set `True` to chunk automatically. If you want a single pass, set `False`.
