AI Engineering AI Workflows

Production AI architecture: RAG, agentic systems, graph RAG, hybrid search, evals and MCP.

Overview

AI engineering workflows are the building blocks every other department depends on — retrieval, planning, evaluation, observability and protocol-level interop. The patterns below are graph-linked to the architecture, prompt, agent and tool registries so you can compose them confidently.

Workflows in this category

  • Retrieval-Augmented Generation — Retrieval-Augmented Generation grounds an LLM in private knowledge by retrieving relevant context from a vector database before generation.
  • Agentic Systems — Agentic systems give an LLM the ability to plan, call tools, and execute multi-step tasks autonomously.
  • Research Assistant — A research assistant decomposes complex questions, retrieves grounded sources, reasons across them and synthesises cited answers.
  • Multimodal Assistant — A multimodal assistant accepts images, audio and text and produces grounded answers, edits or generations.
  • Agentic RAG — Agentic RAG upgrades a standard single-shot retrieval pipeline with a planning agent that can reformulate queries, switch retrieval strategies, validate the retrieved evidence against the question and iterate until the answer meets a confidence threshold.
  • Graph RAG — Use a knowledge graph alongside vector retrieval to ground LLM answers in entity-rich, relationship-aware context.
  • Hybrid Search — Blend lexical (BM25) and semantic retrieval with reranking for state-of-the-art recall and precision.
  • Evaluation Pipeline — Continuous offline and online evaluation harness with regression detection, dataset versioning and dashboards.
  • MCP Workflow — Expose enterprise systems to LLMs via the Model Context Protocol with auth, scope control and audit logs.
  • Multi-Agent Orchestration — Plan, route and supervise multi-agent workflows with typed message contracts and budget circuit-breakers.
  • RAG Evaluation — Continuous evaluation harness for RAG pipelines with groundedness, faithfulness and answer-relevance scoring.
  • Guardrails Pipeline — Composable pre/post-generation guardrail layer covering PII, toxicity, jailbreaks and policy violations.
  • Model Routing — Dynamic model routing across providers and tiers based on intent, cost ceiling and latency SLA.
  • Synthetic Data Generation — Generate, evaluate and govern synthetic datasets for evals, fine-tuning and offline testing.
  • Fine-Tuning Pipeline — End-to-end fine-tuning pipeline with data prep, eval, training and deploy stages plus rollback gates.
  • Prompt Management — Versioned prompt registry with diff review, eval-gated promotion and per-environment rollout.
  • Vector Index Management — Operational playbook for vector-index lifecycle: schema, chunking, reindex, freshness and tiered storage.
  • Semantic Cache — Production semantic caching layer with similarity gating, TTL policy and cache-quality monitoring.
  • LLM Observability — End-to-end observability stack for LLM apps: traces, evals, cost, drift and incident response.
  • Benchmark Bot — Benchmark Bot is a conversational RAG application over the ModelRefs canonical benchmark graph.
