Capability · NLP, LLM & RAG

Grounded LLMs over your own knowledge.

Where SoftsensorX began — retrieval-augmented generation, NLP and conversational AI. RAG-Fusion and agentic retrieval, semantic search, and streaming chat that answers from your documents and data, not the model's memory — every response traceable to its source.

The challenge

LLMs that sound right but aren't.

Hallucination

A raw LLM invents plausible answers with no grounding — unacceptable over legal, financial, clinical or brand-critical content.

Knowledge trapped in text

Decades of documents, talks and articles that no one can actually query conversationally.

No traceability

Answers with no citation can't be trusted or audited — users need to see exactly where each one came from.

What we build

The full RAG & LLM stack.

Advanced retrieval, grounded generation and conversational AI — engineered for production.

01

RAG pipelines & RAG-Fusion

Grounded retrieval-augmented generation with multi-query RAG-Fusion, hybrid semantic + keyword search, metadata filtering and re-ranking for precise, source-linked answers.

02

Agentic RAG

Multi-step agent pipelines that plan, retrieve, compare-and-contrast and synthesize detailed answers across large corpora — reasoning, not just lookup.

03

Conversational & streaming chat

WebSocket streaming assistants with chat memory and multi-tenant namespaces — real-time conversational access to your knowledge base.

04

Semantic search & embeddings

Vector search on Pinecone with LlamaIndex and sentence-transformers — chunking, embedding and indexing strategies tuned to your content.

05

Fine-tuning, guardrails & evaluation

Prompt engineering, fine-tuning, guardrails and evaluation harnesses — provider-agnostic across OpenAI, GLM, DeepSeek and open models, cost-observed.

06

Multimodal & document chat

Chat over PDFs, images and mixed content with page-level grounding — pairs with Document AI and Computer Vision.

How it works

From corpus to grounded answer.

Retrieval-augmented generation pipeline: ingest and chunk content, embed into a vector store, RAG-Fusion retrieval and re-ranking, grounded LLM generation, and a source-traceable answer.

FAQ

Common questions.

What is RAG (retrieval-augmented generation) and why does it matter?

RAG grounds an LLM's answers in your own documents and data rather than its training memory — so responses are current, verifiable and traceable to a source. It's the reliable way to put LLMs over enterprise knowledge without hallucination.

What RAG and LLM techniques does Softsensor use?

RAG-Fusion multi-query retrieval, agentic RAG pipelines, hybrid semantic + keyword search with metadata filtering and re-ranking, streaming conversational chat with memory, and guardrails — built with LangChain, LlamaIndex, Pinecone, sentence-transformers and OpenAI or open models.

How do you prevent LLM hallucination?

Answers are generated strictly from retrieved, source-linked context, with re-ranking, confidence signals, guardrails and evaluation — every response traces back to the passage it came from.

Can you build a chatbot over our own content or documents?

Yes — we build conversational assistants and semantic search over document, web and multimodal corpora, with multi-tenant namespaces and streaming responses, deployed on your cloud.
