# Vectara

> Vectara is a Palo Alto-based enterprise AI company building a trusted, end-to-end platform for retrieval-augmented generation (RAG) and AI agents. Founded in 2022 by former Google AI researchers, it lets companies embed grounded, citation-backed GenAI - conversational assistants, semantic search, and agents - into their products while actively detecting and correcting hallucinations at runtime. Its stack includes the Boomerang embedding model, the RAG-tuned Mockingbird LLM, the open-source Hughes Hallucination Evaluation Model (HHEM), and a Guardian Agent layer, positioning Vectara as a leader in factual, secure, compliance-ready enterprise AI.

- **Founded:** 2022

- **Products:** Vectara Platform (Enterprise Agent Platform), Boomerang, Mockingbird LLM, Hughes Hallucination Evaluation Model (HHEM), Factual Consistency Score
- **Notable:** Helped define and name the 'RAG-as-a-Service' category before RAG became mainstream terminology., Raised $53.5M total, including a $25M Series A in July 2024., Released Mockingbird, a RAG-purpose-built LLM reported to outperform GPT-4 by 26% on BERT-F1 for RAG outputs.

## Products & services

- **Vectara Platform (Enterprise Agent Platform)** — End-to-end RAG-as-a-Service platform that handles data ingestion, embeddings, retrieval, reranking, and grounded generation via API, enabling conversational assistants, semantic search, and AI agents.
- **Boomerang** — Vectara's proprietary neural vector embedding / retrieval model powering multilingual semantic and hybrid search.
- **Mockingbird LLM** — A large language model purpose-built and fine-tuned for RAG, optimized to stay grounded in source facts; Vectara reported it outperforming GPT-4 by 26% on BERT-F1 for RAG-style outputs.
- **Hughes Hallucination Evaluation Model (HHEM)** — Open-source model and public leaderboard for detecting and scoring hallucinations in LLM outputs, widely referenced across the industry.
- **Factual Consistency Score** — A production tool that scores how well a generated answer is supported by the retrieved source material.
- **Guardian Agent** — Runtime guardrail technology that actively detects and corrects hallucinations rather than merely flagging them, underpinning Vectara's agentic offerings.
