 3.⠀**`base_url`**:  
    - If your provider has a custom endpoint
 
-4.⠀**Retry/backoff controls** *(optional)*:  
-   - `backoff_base_delay` *(default `2` seconds)* – base delay inserted before the first retry when the provider returns a rate-limit response.  
-   - `backoff_max_attempts` *(default `3`)* – total number of attempts (initial call plus retries) before the request is surfaced as an error.  
-   - `backoff_exponential_factor` *(default `2`)* – growth rate for the retry delay (`delay = base_delay * factor^attempt`).  
-   - These values are forwarded to the shared `perform_completion_with_backoff` helper, ensuring every strategy that consumes your `LLMConfig` honors the same throttling policy.

 ```python
-llm_config = LLMConfig(
-    provider="openai/gpt-4o-mini",

-    backoff_exponential_factor=3, #optional
