OpenAI, the artificial intelligence research laboratory, has launched ChatGPT-4, an upgraded version of its popular chatbot. ChatGPT-4 is reportedly more powerful, private, and able to handle longer conversations than its predecessor. The chatbot uses a larger model and improved training techniques, allowing it to generate more nuanced and detailed responses. OpenAI also introduced a new feature called Instruct-1, a more precise way to guide the chatbot's responses, and a new interface for easier interaction with the AI.
LangChain has many advanced retrieval methods to help address these challenges. (1) Multi representation indexing: Create a document representation (like a summary) that is well-suited for retrieval (read about this using the Multi Vector Retriever in a blog post from last week). (2) Query transformation: in this post, we'll review a few approaches to transform humans questions in order to improve retrieval. (3) Query construction: convert human question into a particular query syntax or language, which will be covered in a future post
