Model OpenAI di LangChain!

Model seri GPT dari OpenAI termasuk LLM berkinerja tertinggi saat ini. Model ini tersedia melalui API OpenAI, yang dapat Anda gunakan dengan mudah menggunakan LangChain.

Biasanya, menggunakan model OpenAI memerlukan kunci API pribadi untuk penagihan biaya model. Dalam kursus ini, Anda tidak perlu membuat atau memberikan kunci API OpenAI. Placeholder "<OPENAI_API_TOKEN>" akan mengirim permintaan yang valid ke API. Jika Anda membuat banyak permintaan dalam waktu singkat, Anda mungkin akan mengalami RateLimitError. Jika ini terjadi, harap jeda sejenak lalu coba lagi.

Welcome to the LangChain framework for building applications on LLMs! You'll learn about the main components of LangChain, including models, chains, agents, prompts, and parsers. You'll create chatbots using both open-source models from Hugging Face and proprietary models from OpenAI, create prompt templates, and integrate different chatbot memory strategies to manage context and resources during conversations.

Time to level up your LangChain chains! You'll learn to use the LangChain Expression Language (LCEL) for defining chains with greater flexibility. You'll create sequential chains, where inputs are passed between components to create more advanced applications. You'll also begin to integrate agents, which use LLMs for decision-making.

One limitation of LLMs is that they have a knowledge cut-off due to being trained on data up to a certain point. In this chapter, you'll learn to create applications that use Retrieval Augmented Generation (RAG) to integrate external data with LLMs. The RAG workflow contains a few different processes, including splitting data, creating and storing the embeddings using a vector database, and retrieving the most relevant information for use in the application. You'll learn to master the entire workflow!
