    Method●Since v0.1

    lookup

    Look up based on prompt and llm_string.

    A cache implementation is expected to generate a key from the 2-tuple of prompt and llm_string (e.g., by concatenating them with a delimiter).

    Copy
    lookup(
      self,
      prompt: str,
      llm_string: str
    ) -> RETURN_VAL_TYPE | None

    Parameters

    NameTypeDescription
    prompt*str

    A string representation of the prompt.

    In the case of a chat model, the prompt is a non-trivial serialization of the prompt into the language model.

    llm_string*str

    A string representation of the LLM configuration.

    This is used to capture the invocation parameters of the LLM (e.g., model name, temperature, stop tokens, max tokens, etc.).

    These invocation parameters are serialized into a string representation.
