[Bug]: Grok response modifies input model name, affects completion_cost

[ming-jeng]

What happened?

Get this error Exception: This model isn't mapped yet. model=xai/grok-3-mini, custom_llm_provider=xai. Add it here - https://github.com/BerriAI/litellm/blob/main/model_prices_and_context_window.json.

Notice the model name changes from xai/grok-3-mini-beta to xai/grok-3-mini, which is not a model name currently in the model_prices_and_context_window.json.

Maybe it shouldn't modify the input model name?
