 == Function Calling
 
-WARNING: As of 30th of April 2023, the Vertex AI `Gemini Pro` model has significantly degraded the support for function calling! While the feature is still available, it is not recommended for production use.
-Apparently the Gemini Pro can not handle anymore the function name correctly.
-The parallel function calling is gone as well.
-
 You can register custom Java functions with the VertexAiGeminiChatModel and have the Gemini Pro model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions.
 This is a powerful technique to connect the LLM capabilities with external tools and APIs.
