 * ```typescript
 * const sessionId = randomUUID();

 * // Initialize ZepCloudMemory with session ID and API key
 * const memory = new ZepCloudMemory({
 *   sessionId,
 *   apiKey: "<zep api key>",
 * });

 * });
 *
 * // Create a ConversationChain with the model and memory
 * const chain = new ConversationChain({ llm: model, memory });
 *
 * // Example of calling the chain with an input
 * const res1 = await chain.call({ input: "Hi! I'm Jim." });
 * console.log({ res1 });
 *
 * // Follow-up call to the chain to demonstrate memory usage
 * const res2 = await chain.call({ input: "What did I just say my name was?" });
 * console.log({ res2 });
 *
 * // Output the session ID and the current state of memory
 * console.log("Session ID: ", sessionId);
 * console.log("Memory: ", await memory.loadMemoryVariables({}));
