builder

public static GoogleAiGeminiChatModel.GoogleAiGeminiChatModelBuilder builder()

chat

public ChatResponse chat(ChatRequest chatRequest)

Description copied from interface: ChatLanguageModel

This is the main API to interact with the chat model. A temporary default implementation of this method is necessary until all ChatLanguageModel implementations adopt it. It should be removed once that occurs.

Specified by:

chat in interface ChatLanguageModel

Parameters:

chatRequest - a ChatRequest, containing all the inputs to the LLM

Returns:

a ChatResponse, containing all the outputs from the LLM

supportedCapabilities

public Set<Capability> supportedCapabilities()

Specified by:

supportedCapabilities in interface ChatLanguageModel

listeners

public List<ChatModelListener> listeners()

Specified by:

listeners in interface ChatLanguageModel

provider

public ModelProvider provider()

Specified by:

provider in interface ChatLanguageModel
