Add support Vertex AI Gemini uses a public image URL (#14949)
## What Since `langchain_google_genai.ChatGoogleGenerativeAI` supported A public image URL, we add to support it in `langchain.chat_models.ChatVertexAI` as well. ### Example ```py from langchain.chat_models.vertexai import ChatVertexAI from langchain_core.messages import HumanMessage llm = ChatVertexAI(model_name="gemini-pro-vision") image_message = { "type": "image_url", "image_url": { "url": "https://python.langchain.com/assets/images/cell-18-output-1-0c7fb8b94ff032d51bfe1880d8370104.png", }, } text_message = { "type": "text", "text": "What is shown in this image?", } message = HumanMessage(content=[text_message, image_message]) output = llm([message]) print(output.content) ``` ## Refs - https://python.langchain.com/docs/integrations/llms/google_vertex_ai_palm - https://python.langchain.com/docs/integrations/chat/google_generative_aipull/15078/head
