THEN Set the `rope_freq_base` parameter to 500000 (or recalculate for extended context) and ensure `rope_freq_scale` is not overridden by LangChain's hardcoded defaults. Pass these as `model_kwargs` to `LlamaCpp` or set them directly in the constructor if supported. Verify the model metadata shows the correct value.

llm = LlamaCpp(

    n_ctx=8192,
    model_kwargs={'rope_freq_base': 500000, 'rope_freq_scale': 1.0}
