Background
The journey of language models from simple text generators to sophisticated tools capable of executing complex tasks has been marked by significant developments in both their architecture and application. Historically, the development of Large Language Models (LLMs) such as GPT has undergone various phases, starting from basic natural language processing tasks to now serving as core components in diverse applications through tool use.
Initially, LLMs were trained merely to predict the next word in a sequence, but the introduction of transformer architectures changed the landscape. This evolution allowed LLMs to scale to unprecedented sizes, ultimately leading to applications that leverage these models as intelligent agents capable of interfacing with external tools. This shift underpins the concept of tool use within LLM applications, where models are not isolated in their operation but are integrated into broader systems to perform complex tasks.
A critical advancement in this evolution is the development of frameworks like LangChain, AutoGen, and CrewAI, which facilitate the orchestration of LLMs with external tools and data sources. These frameworks provide the scaffolding necessary for integrating LLMs with vector databases such as Pinecone, Weaviate, and Chroma, essential for retrieval-augmented generation (RAG) architectures.
The architecture of RAG is pivotal, enabling LLMs to provide factual, domain-specific, and up-to-date responses. Here's a typical workflow: user query → embedding & vector search → context injection → LLM generation. This method relies on embedding queries into vector spaces and retrieving relevant information, which is injected into the model's context to generate informed responses.
