Package dev.langchain4j.model.openai

Class OpenAiStreamingLanguageModel

java.lang.Object

dev.langchain4j.model.openai.OpenAiStreamingLanguageModel

All Implemented Interfaces:

dev.langchain4j.model.language.StreamingLanguageModel, dev.langchain4j.model.language.TokenCountEstimator

public class OpenAiStreamingLanguageModel
extends Object
implements dev.langchain4j.model.language.StreamingLanguageModel, dev.langchain4j.model.language.TokenCountEstimator

Represents an OpenAI language model with a completion interface, such as gpt-3.5-turbo-instruct. The model's response is streamed token by token and should be handled with StreamingResponseHandler. However, it's recommended to use OpenAiStreamingChatModel instead, as it offers more advanced features like function calling, multi-turn conversations, etc.
