        base_url: The base URL for the API. This is necessary for local LLMs. It is also used for Azure embeddings.
        api_version: The version of the API.
        embedding_model: The embedding model to use.
        embedding_base_url: The base URL for the embedding API.
        embedding_deployment_name: The name of the deployment for the embedding API. This is used for Azure OpenAI.

        aws_secret_access_key: The AWS secret access key.
        aws_region_name: The AWS region name.
        num_retries: The number of retries to attempt.
        retry_multiplier: The multiplier for the exponential backoff.
        retry_min_wait: The minimum time to wait between retries, in seconds. This is exponential backoff minimum. For models with very low limits, this can be set to 15-20.
        retry_max_wait: The maximum time to wait between retries, in seconds. This is exponential backoff maximum.
        timeout: The timeout for the API.
        max_message_chars: The approximate max number of characters in the content of an event included in the prompt to the LLM. Larger observations are truncated.
        temperature: The temperature for the API.
        top_p: The top p for the API.
        custom_llm_provider: The custom LLM provider to use. This is undocumented in openhands, and normally not used. It is documented on the litellm side.
        max_input_tokens: The maximum number of input tokens. Note that this is currently unused, and the value at runtime is actually the total tokens in OpenAI (e.g. 128,000 tokens for GPT-4).
        max_output_tokens: The maximum number of output tokens. This is sent to the LLM.
        input_cost_per_token: The cost per input token. This will available in logs for the user to check.
        output_cost_per_token: The cost per output token. This will available in logs for the user to check.
        ollama_base_url: The base URL for the OLLAMA API.
