    start_time = time.time()
    llm = AnyscaleLLM(api_key="esecret_*****")
    llm.load()

Thanks for the PR @davidberenstein1957!

LGTM, great work! Thanks for also removing the model defaults, feel free to merge core-refactor in your branch, delete the load method from AnyscaleLLM and then we can merge, thanks again!

Suggested change

	model: the model name to use for the LLM, e.g., `google/gemma-7b-it`. [Supported models](https://docs.endpoints.anyscale.com/text-generation/supported-models/google-gemma-7b-it).

Sadly this is not defined haha

No need to define this function, as there's already an update on core-refactor, so feel free to merge the changes from that branch and remove this function instead 👍🏻
