- The new functionality for defining and using OpenAiFunctionTool is introduced here, but there are no corresponding tests to verify its integration into the chat completion request. Please add test cases that exercise this functionality.

- [nitpick] The Javadoc comment includes extraneous text ('tool.getClass().getName()); }') that should be removed to improve clarity and professionalism.

You could put all of this into a convenience function of OpenAiChatCompletionResponse.
Because the client already has the reference to the OpenAiFunctionTool

OpenAiMessage.tool(currentWeather.toString(), functionCall.getId()) could also be a convenience so th customer doesn't have to build it.

The is no use-case for OpenAiFunctionTool to be immutable.
Also, is there ever going to be another OpenAiTool that is not OpenAiFunctionTool?
