User input + base prompt = Prompt Template
Achieve a specific task by linking multiple components together.
Chains allow us to combine multiple components together to create a single, coherent application. For example, we can create a chain that takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM. We can build more complex chains by combining multiple chains together, or by combining chains with other components.
- Document loaders - extract text from the source documents
- Text splitters - split long pieces of text into chunks
- Embedding models - convert text to numbers, such that similar meaning texts are closer in numbers to each other
- Vector stores - numbers are stored in a database called Vector Database
