Summary

In conclusion, we note that exploring the downstream impact of some Pinecone configuration choices on response quality, cost and latency is an important part of the LLM app development process, ensuring that we make the choices that lead to the app performing the best. Overall, TruLens and Pinecone are the perfect combination for building reliable RAG-style applications. Pinecone provides a way to efficiently store and retrieve context used by LLM apps, and TruLens provides a way to track and evaluate each iteration of your application.

Pinecone provides a way to efficiently store and retrieve context used by LLM apps, and TruLens provides a way to track and evaluate each iteration of your application.

Summary

In conclusion, we note that exploring the downstream impact of some Pinecone configuration choices on response quality, cost and latency is an important part of the LLM app development process, ensuring that we make the choices that lead to the app performing the best. Overall, TruLens and Pinecone are the perfect combination for building reliable RAG-style applications. Pinecone provides a way to efficiently store and retrieve context used by LLM apps, and TruLens provides a way to track and evaluate each iteration of your application.

Why Pinecone?

Large language models alone have a hallucination problem. Several decades of machine learning research have optimized models, including modern LLMs, for generalization, while actively penalizing memorization. However, many of today’s applications require factual, grounded answers. LLMs are also expensive to train, and provided by third party APIs. This means the knowledge of an LLM is fixed. Retrieval-augmented generation (RAG) is a way to reliably ensure models are grounded, with Pinecone as the curated source of real world information, long term memory, application domain knowledge, or whitelisted data.

In the RAG paradigm, rather than just passing a user question directly to a language model, the system retrieves any documents that could be relevant in answering the question from the knowledge base, and then passes those documents (along with the original question) to the language model to generate the final response. The most popular method for RAG involves chaining together LLMs with vector databases, such as the widely used Pinecone vector DB.

In this process, a numerical vector (an embedding) is calculated for all documents, and those vectors are then stored in a database optimized for storing and querying vectors. Incoming queries are vectorized as well, typically using an encoder LLM to convert the query into an embedding. The query embedding is then matched via embedding similarity against the document embeddings in the vector database to retrieve the documents that are relevant to the query.

Pinecone makes it easy to build high-performance vector search applications, including retrieval-augmented question answering. Pinecone can easily handle very large scales of hundreds of millions and even billions of vector embeddings. Pinecone’s large scale allows it to handle long term memory or a large corpus of rich external and domain-appropriate data so that the LLM component of RAG application can focus on tasks like summarization, inference and planning. This setup is optimal for developing a non-hallucinatory application.  
In addition, Pinecone is fully managed, so it is easy to change configurations and components. Combined with the tracking and evaluation with TruLens, this is a powerful combination that enables fast iteration of your application.

The most popular method for RAG involves chaining together LLMs with vector databases, such as the widely used Pinecone vector DB.

In this process, a numerical vector (an embedding) is calculated for all documents, and those vectors are then stored in a database optimized for storing and querying vectors. Incoming queries are vectorized as well, typically using an encoder LLM to convert the query into an embedding. The query embedding is then matched via embedding similarity against the document embeddings in the vector database to retrieve the documents that are relevant to the query.

Pinecone makes it easy to build high-performance vector search applications, including retrieval-augmented question answering. Pinecone can easily handle very large scales of hundreds of millions and even billions of vector embeddings. Pinecone’s large scale allows it to handle long term memory or a large corpus of rich external and domain-appropriate data so that the LLM component of RAG application can focus on tasks like summarization, inference and planning. This setup is optimal for developing a non-hallucinatory application.  
In addition, Pinecone is fully managed, so it is easy to change configurations and components. Combined with the tracking and evaluation with TruLens, this is a powerful combination that enables fast iteration of your application.

Why Pinecone?

Large language models alone have a hallucination problem. Several decades of machine learning research have optimized models, including modern LLMs, for generalization, while actively penalizing memorization. However, many of today’s applications require factual, grounded answers. LLMs are also expensive to train, and provided by third party APIs. This means the knowledge of an LLM is fixed. Retrieval-augmented generation (RAG) is a way to reliably ensure models are grounded, with Pinecone as the curated source of real world information, long term memory, application domain knowledge, or whitelisted data.

In the RAG paradigm, rather than just passing a user question directly to a language model, the system retrieves any documents that could be relevant in answering the question from the knowledge base, and then passes those documents (along with the original question) to the language model to generate the final response.
