A Pinecone alternative that’s easier to use, more cost-effective, and provides better search relevance.

Vectara is a Pinecone alternative that enables organizations and developers to build or improve their website or application search functions while leveraging large language models to deliver fast, highly-relevant results without high costs and complex maintenance.

How Vectara Compares

Complete Search Pipeline

Vectara’s search-as-a-service platform provides a complete ML search pipeline. Its internally developed LLM architecture allows it to train data to provide a higher level of relevance. Vectara maintains the entire search pipeline.

Pinecone’s database-as-a-service does not provide everything required to build a full search functionality. You will need to use other technologies to build a full search function, and the burden is on the user to assemble, build, maintain, and operate the pipeline.

Overall Ease of Use

Using Vectara requires no specialized search engineering or AI/ML knowledge. You can index your first set of data and be up and running on using Vectara in 5 minutes.

Without experience in building a search pipeline, there is a steep learning curve associated with using Pinecone along with other necessary technologies to build search.

Set Up and Maintenance

  • Start instantly. Connect via simple REST or gRPC API endpoints.
  • No language configuration.
  • Vectara’s InstantIndex feature allows developers to ingest and process new data through a full service search pipeline in less than one second. Likewise, its File Upload API enables automated file extraction and processing.
  • Complex set-up. Setting up hosting and Integrating data flows between Pinecone, the ebedding provider, and the search interface requires substantial set up.
  • Using Pinecone also requires substantial maintenance as data changes or is updated.

Data Ingesting and Processing

Vectara’s InstantIndex makes content more discoverable and easily processed. Developers ingest and process new data through a full service search pipeline in < 1 second.

Once data is collected, it needs to be pre-processed, cleaned-up, and segmented appropriately before it is indexed.

Relevance

  • Vectara’s 100% neural ranking model using LLMs along with its relevance enhancing features enables more relevant search results.
  • Neural search is often more effective than vector search, particularly when dealing with complex queries and large collections of documents.

Embedding vectors are not part of the Pinecone product offering, and developers will need to use models from embedding providers. They must insure such models remain consistent with the intent of the application and with the embedding providers, or relevance will be affected negatively.

Cost

Vectara offers a generous free version of its service. 
Users can upload a 50 MB of data into their indexes and use 15,000 queries each month for free. Upgrading to the paid plan is inexpensive.

Pinecone also offers a free plan, but it is very limited (single pod, single project, single environment.) More importantly, Pinecone’s pricing represents only part of the cost of building a search function with its use. Fees paid for hosting and to an embedding provider have to be considered as well. The cost of higher development effort for set-up and maintenance should also be considered.

Build for the Future

Vectara’s LLM-powered platform that offers a complete, integrated information retrieval pipeline will enable you to take advantage of a continuously improving, fully integrated service.

To take advantage of features Pinecone adds in the future, users will have to build out and expand the other components of their search model as well.

What is Pinecone?

Pinecone.io is a cloud-based vector-database as-a-service that provides a database for inclusion within semantic search applications and data pipelines. Pinecone supports the storage of vector embeddings that are output from third party models such as those hosted at HuggingFace or delivered via APIs such as those offered by Cohere or OpenAI. At its core, the vector database provides fast and scalable approximate nearest neighbor search functionality (in the embedding space) that computes similarity scores between queries and relevant content.

Key Pinecone Features

Pinecone’s features include:

Who is Pinecone for?

Pinecone is designed for use by search and data engineers who wish to assemble their own search pipeline for use cases like similarity search and wish to select (or implement) each element of the search pipeline, like the vector database and the embeddings model, and build and maintain the end-to-end search solution. They can use embeddings providers like OpenAI or Cohere to create embeddings for queries and content, store those in the Pinecone platform, and use its scalable similarity search to build the application.

Developers without experience in developing similarity search applications are likely to face a steep learning curve. Users of Pinecone might also expect to invest in implementing other elements required to build the search function and invest substantial time and effort in ongoing maintenance to keep the search pipeline efficient and performing well as they add data or update their data over time.

Pinecone Use Cases

Some of the most common Pinecone search use cases are:

Challenges with Pinecone

Building an end-to-end LLM-powered application is often more complex than it initially appears.  Pinecone is just one component of the overall architecture, and the developer building the search application will have to pay careful attention to the integration of all the components (and their respective APIs) and how they interact with each other. Furthermore, after the initial build, maintaining that application and hosting it requires additional resources 
and investment.

A typical architecture using Pinecone is shown in figure 1 below:

There are multiple steps that need to be built into any search application using the Pinecone database:

01

Documents and/or other content need to be converted into embedding vectors. This is done for each document in turn (using an embedding model provider from HuggingFace, Cohere or OpenAI), and the embedding vectors are then stored in Pinecone along with the documents they represent.

02

When a query is presented by the user, it is converted into a query embedding vector (using the same embedding provider); subsequently a similarity search is performed by Pinecone to match the query embedding to the closest document embedding using nearest-neighbor search algorithms.

03

Once the top results are identified by Pinecone in step 2, the result-set is sent back to the user for presentation, and potentially additional generative processing like summarization.

Pinecone.io provides a fast and scalable database for use in building similarity search, however the developer using Pinecone must ensure that all the other components work in harmony both from a systems engineering perspective as well as from a modeling perspective.

A few key potential hurdles to keep in mind are:

Pinecone Summary

In summary, setting up and using Pinecone in itself is not trivial and requires learning the platform and gaining real world experience with using it; on top of that, designing and implementing the interaction with the embeddings provider, implementing document parsing and segmentation, connecting with the user interface and taking care of hosting everything on the cloud make this a non-trivial task.

Cost is another consideration; its pay-as-you-go pricing model can become surprisingly expensive as you scale up, especially as you introduce multiple collections (document indexes). In addition, when you use the Pinecone database, you need to factor the additional cost of development, maintenance, hosting, operation and per-token, per-API or hosted-inference cost of using the embeddings provider like OpenAI or Cohere.

Finally, Pinecone is still an early stage company, and their technology infrastructure has been prone to outages. In March of 2023, Pinecone experienced a partial database outage that affected some of their customers’ indexes.

What is Vectara?

Vectara is LLM-powered search-as-a-service. The platform provides a complete ML search pipeline that includes extract, encode, index, retrieve, rerank, and calibrate functions. The platform is API-addressable. Developers can efficiently embed an NLP model for app and site search. It is a cloud-native, LLM-powered search platform built to serve developers at companies of all sizes and enable them build or improve search functions in their sites and applications that will operate at market leading speeds. Using advanced research in AI, Vectara applies large language models to perform information retrieval (rather than using keywords) and deliver highly relevant results.

Key Vectara Features

Vectara’s features include:

Proprietary LLM Architecture

Vectara uses Zero-shot models in LLM-powered search, a multi-model, neural network-based information retrieval pipeline built using Vectara-created LLMs for fast, cost-effective retrieval with high precision and recall.

API First

Vectara is API-first. It features quick set-up and easy-to-use APIs in a platform that enables developers to easily build, debug and test applications of semantic search. This is a unified API set with associated documentation and playground that allows full control over the entire pipeline, not just the database element or the embeddings element or the reranker or the text extractor, etc.

API-based features include:

  • Confidence Scores: In order to provide feedback on the search results, Vectara provides AI-calculated confidence scores which allow users to get direct access to the ranking scores assigned by the platform.
  • Custom Dimensions:Vectara allows users to then customize their search results using its custom dimensions feature which allows them to prioritize search results by customer-defined measures of relevance.
  • Metadata Annotation: Users can define annotation labels to data or use platform automated annotation. Annotation data can be stored next to your documents instead of referring to external databases.

Instant Index

Vectara’s InstantIndex feature allows developers to ingest and process new data through a full service search pipeline in sub-second time. Likewise, its File Upload API enables automated file extraction and processing.

Processes Most Document Formats

Vectara can index most types of files and data.  Vectara automatically extracts text from documents of nearly any type, with auto-detection of file formats and multi-stage extraction routines. Vectara can accurately extract text, index it, and create vector embeddings from documents in formats including PDF, Microsoft Word, Microsoft Powerpoint, Open Office, HTML, JSON, XML, email in RFC822, text, RTF, ePUB, or CommonMark. Vectara extracts text from tables, images and other document elements automatically.

LLM-powered Re-ranking

Vectara’s LLM-powered re-ranking is a embedded feature. It is a part of Vectara’s multi-model AI architecture and allows users to re-rank retrieved documents for further precision around a given query.

Rules-based AI

Another customization feature, Rules-based AI, allows you to define and control the responses you provide to users.

Generative AI Features

Vectara also provides generative AI features like its LLM-powered summarization.

  • Summarization: This feature generates compelling summaries of search results, with references, to deliver a verifiable, single answer to any question.
  • Related Content: This feature helps your users discover new ideas and content by providing visibility to other relevant topics.
  • Suggested Responses: This feature delivers accurate responses to questions (no matter how they are asked) from your organization’s data.

Language Agnostic

Vectara is language agnostic. It enables multi-language search and cross-language search. A user on the same site can search in multiple languages to find results in each of those languages. Developers can also use Vectara to provide users with the ability to search in one language for content written in another language.

Security Features

Vectara security features extend across the entirety of the full pipeline at all times.

Security features include:

  • Encryption at Rest and In Transit: This protects data while stored and when moved between two services.
  • Client-managed Encryption Keys: These provide customers with ownership of the encryption keys that protect their data.
  • Client-Configurable (Textless) Data Retention: This provides the option to maximize privacy by processing data into vector embeddings and meta data and then discarding the original documents and text data so that they do not persist in the Vectara system.

Admin Console

Finally, Vectara’s admin console UI provides users and administrators with access to manage user accounts, API keys, corpora, index data, and queries. An administrator has visibility to all the elements, users, and activities across all components of the pipeline within a single UI.
