RAG Pipelines

Ground your LLMs in real knowledge at billion-document scale.

Retrieval-augmented generation turns a general-purpose LLM into a precise, domain-specific expert by grounding every answer in your own data. CogniCloud's RAG stack combines GPU-accelerated vector indexing, hybrid BM25 + dense search, real-time ingestion, and a low-latency inference endpoint into a single coherent pipeline.

The Challenge

Why this is hard.

Enterprise RAG fails in production because the components don't talk to each other efficiently: embedding pipelines are slow, vector databases can't keep up with real-time document updates, and the end-to-end latency makes the product feel sluggish. You need all three layers — retrieval, context assembly, and generation — optimised as a unit.

How CogniCloud helps

Everything you need, built in.

Hybrid BM25 + dense search

Combine sparse keyword matching with dense semantic similarity in a single query. Reciprocal rank fusion merges results with configurable blend weights — catching both exact matches and semantic paraphrases.

GPU-accelerated HNSW indexing

Build a 100M-vector HNSW index in minutes using cuVS (RAPIDS). Nearest-neighbour search saturates GPU SIMD lanes instead of CPU cores — 20× faster than CPU-only implementations.

Real-time document ingestion

New and updated documents are embedded, indexed, and queryable within milliseconds of insertion. No batch ingestion jobs, no index rebuild downtime — your knowledge base is always current.

Prefix-cached context assembly

Long RAG context windows (system prompt + retrieved chunks) are cached at the KV layer. Only the user's question needs fresh computation — reducing cost per query by up to 80%.

Multi-tenant data isolation

Namespace-level isolation ensures complete data separation between tenants. A query from tenant A cannot surface documents from tenant B at any layer of the retrieval stack.

Re-ranking & filtering

Post-retrieval cross-encoder re-ranking and metadata pre-filtering ensure the most relevant chunks make it into context. Relevance scores are surfaced in the response for observability.

How it works

From zero to production in three steps.

01

Ingest your documents

Push documents to the ingestion API. CogniCloud chunks, embeds, and indexes them automatically using your chosen embedding model.

import { CogniCloud } from "@cognicloud/sdk";

const client = new CogniCloud();
await client.vectorStore.upsert({
  namespace: "my-knowledge-base",
  documents: [
    { id: "doc-1", text: "...", metadata: { source: "wiki" } },
    { id: "doc-2", text: "...", metadata: { source: "docs"  } },
  ],
  model: "text-embedding-3-large",
});
// Queryable in < 10ms
02

Retrieve relevant context

Run a hybrid search query. CogniCloud returns the top-k most relevant chunks with metadata and relevance scores.

const results = await client.vectorStore.query({
  namespace:  "my-knowledge-base",
  query:      userMessage,
  topK:       8,
  hybrid:     { alpha: 0.7 },   // 70% dense, 30% BM25
  filter:     { source: "docs" },
  rerank:     true,
});
// p99 latency: 0.8ms
03

Generate a grounded answer

Pass the retrieved chunks as context to the Inference Gateway. The KV-prefix cache makes repeated context nearly free.

const answer = await client.chat({
  model:    "meta-llama/Llama-3-70B-Instruct",
  messages: [
    { role: "system",  content: SYSTEM_PROMPT },
    { role: "user",    content: buildContext(results, userMessage) },
  ],
  stream: true,
});
// TTFT: 7.2ms (94% cache hit on context)
