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.

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.

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.

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.

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.

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.

Setup guide

[TruLens](https://github.com/truera/trulens) is a powerful open source library for evaluating and tracking large language model-based applications. In this guide, we will show you how to use TruLens to evaluate applications built on top of a high performance Pinecone vector database.

[​](#why-trulens)

Why TruLens?

Systematic evaluation is needed to support reliable, non-hallucinatory LLM-based applications. TruLens contains instrumentation and evaluation tools for large language model (LLM)-based applications. For evaluation, TruLens provides a set of feedback functions, analogous to labeling functions, to programmatically score the input, output and intermediate text of an LLM app. Each LLM application request can be scored on its question-answer relevance, context relevance and groundedness. These feedback functions provide evidence that your LLM-application is non-hallucinatory.

In addition to the above, feedback functions also support the evaluation of ground truth agreement, sentiment, model agreement, language match, toxicity, and a full suite of moderation evaluations, including hate, violence and more. TruLens implements feedback functions as an extensible framework that can evaluate your custom needs as well.

During the development cycle, TruLens supports the iterative development of a wide range of LLM applications by wrapping your application to log cost, latency, key metadata and evaluations of each application run. This allows you to track and identify failure modes, pinpoint their root cause, and measure improvement across experiments.

For evaluation, TruLens provides a set of feedback functions, analogous to labeling functions, to programmatically score the input, output and intermediate text of an LLM app. Each LLM application request can be scored on its question-answer relevance, context relevance and groundedness. These feedback functions provide evidence that your LLM-application is non-hallucinatory.

In addition to the above, feedback functions also support the evaluation of ground truth agreement, sentiment, model agreement, language match, toxicity, and a full suite of moderation evaluations, including hate, violence and more. TruLens implements feedback functions as an extensible framework that can evaluate your custom needs as well.

During the development cycle, TruLens supports the iterative development of a wide range of LLM applications by wrapping your application to log cost, latency, key metadata and evaluations of each application run. This allows you to track and identify failure modes, pinpoint their root cause, and measure improvement across experiments.

[​](#why-trulens)

Why TruLens?

Systematic evaluation is needed to support reliable, non-hallucinatory LLM-based applications. TruLens contains instrumentation and evaluation tools for large language model (LLM)-based applications. For evaluation, TruLens provides a set of feedback functions, analogous to labeling functions, to programmatically score the input, output and intermediate text of an LLM app. Each LLM application request can be scored on its question-answer relevance, context relevance and groundedness. These feedback functions provide evidence that your LLM-application is non-hallucinatory.

In addition to the above, feedback functions also support the evaluation of ground truth agreement, sentiment, model agreement, language match, toxicity, and a full suite of moderation evaluations, including hate, violence and more. TruLens implements feedback functions as an extensible framework that can evaluate your custom needs as well.

During the development cycle, TruLens supports the iterative development of a wide range of LLM applications by wrapping your application to log cost, latency, key metadata and evaluations of each application run. This allows you to track and identify failure modes, pinpoint their root cause, and measure improvement across experiments.

Context: Using LlamaIndex and Pinecone to build semantic search and RAG applications

LlamaIndex is a framework for connecting data sources to LLMs, with its chief use case being the end-to-end development of retrieval augmented generation (RAG) applications. LlamaIndex provides the essential abstractions to more easily ingest, structure, and access private or domain-specific data in order to inject these safely and reliably into LLMs for more accurate text generation. It’s available in Python and Typescript.

Seamlessly integrate Pinecone vector database with LlamaIndex to build semantic search and RAG applications.

[LlamaIndex](https://www.llamaindex.ai/) is a framework for connecting data sources to LLMs, with its chief use case being the end-to-end development of [RAG applications](https://www.pinecone.io/learn/retrieval-augmented-generation/). Compared to other similar frameworks, LlamaIndex offers a wide variety of tools for pre- and post-processing your data.

This guide shows you how to use LlamaIndex and Pinecone to both perform traditional semantic search and build a RAG pipeline. Specifically, you will:

* Load, transform, and vectorize sample data with LlamaIndex
* Index and store the vectorized data in Pinecone
* Search the data in Pinecone and use the results to augment an LLM call
* Evaluate the answer you get back from the LLM

This guide demonstrates only one way out of many that you can use LlamaIndex as part of a RAG pipeline. See LlamaIndex’s section on [Advanced RAG](https://docs.llamaindex.ai/en/stable/optimizing/advanced%5Fretrieval/advanced%5Fretrieval.html) to learn more about what’s possible.

[LlamaIndex](https://www.llamaindex.ai/) is a framework for connecting data sources to LLMs, with its chief use case being the end-to-end development of [RAG applications](https://www.pinecone.io/learn/retrieval-augmented-generation/). Compared to other similar frameworks, LlamaIndex offers a wide variety of tools for pre- and post-processing your data.

This guide shows you how to use LlamaIndex and Pinecone to both perform traditional semantic search and build a RAG pipeline. Specifically, you will:

* Load, transform, and vectorize sample data with LlamaIndex
* Index and store the vectorized data in Pinecone
* Search the data in Pinecone and use the results to augment an LLM call
* Evaluate the answer you get back from the LLM

This guide demonstrates only one way out of many that you can use LlamaIndex as part of a RAG pipeline. See LlamaIndex’s section on [Advanced RAG](https://docs.llamaindex.ai/en/stable/optimizing/advanced%5Fretrieval/advanced%5Fretrieval.html) to learn more about what’s possible.

Context: Using LlamaIndex and Pinecone to build semantic search and RAG applications

LlamaIndex is a framework for connecting data sources to LLMs, with its chief use case being the end-to-end development of retrieval augmented generation (RAG) applications. LlamaIndex provides the essential abstractions to more easily ingest, structure, and access private or domain-specific data in order to inject these safely and reliably into LLMs for more accurate text generation. It’s available in Python and Typescript.

Seamlessly integrate Pinecone vector database with LlamaIndex to build semantic search and RAG applications.
