Design LLM Applications with AI

Building production LLM applications involves more than just calling an API. You need retrieval pipelines, vector databases, prompt management, guardrails, evaluation systems, and cost controls, all connected in the right architecture.

InfraSketch generates complete LLM application architectures from natural language. Whether you are building a RAG system, a production chatbot, or a multi-agent workflow, describe what you need and get an architecture diagram in seconds. InfraSketch is itself built on LangGraph and Claude, so it understands LLM architecture patterns from first-hand experience.

Features

🤖

LLM Application Architecture

Generate complete architectures for LLM-powered applications including RAG pipelines, chatbots, and AI agents from natural language.

🔍

RAG System Design

Design retrieval-augmented generation systems with document ingestion, embedding pipelines, vector databases, and generation layers.

🔗

Agent Architectures

Diagram multi-agent systems, tool-calling agents, and orchestration workflows with LangGraph, LangChain, or custom frameworks.

💬

Conversational Refinement

Refine your LLM architecture through chat. Add guardrails, caching layers, evaluation pipelines, or cost optimization strategies.

📄

Auto Design Documents

Generate detailed documentation covering system components, data flows, API contracts, prompt strategies, and scaling considerations.

📤

Export and Share

Export LLM architecture diagrams as PNG, PDF, or Markdown for design reviews, technical documentation, or presentations.

Use Cases

📚

RAG Applications

Design document Q&A systems, knowledge bases, and semantic search applications with vector databases and retrieval pipelines.

💬

Production Chatbots

Architect chatbot systems with conversation management, tool integration, guardrails, and observability for production deployment.

🧠

AI Agent Systems

Design agentic AI architectures with multi-agent orchestration, tool calling, state management, and human-in-the-loop patterns.

🏗️

LLM Infrastructure

Plan LLM serving infrastructure with prompt caching, model routing, cost management, and evaluation pipelines.

How It Works

1

Describe Your LLM Application

Write a description like "Design a customer support chatbot with RAG over our knowledge base, tool calling for order lookups, and conversation memory"

2

AI Generates Architecture

The AI creates a complete architecture showing your LLM orchestration, data pipelines, vector stores, tools, and infrastructure

3

Refine Through Chat

Ask the AI to add guardrails, caching, evaluation pipelines, or scale specific components. Your diagram updates in real-time.

4

Export Documentation

Generate comprehensive design docs with component details, data flows, API contracts, and deployment strategies

Example LLM Architecture Prompts

RAG Knowledge Base

"Design a RAG system for internal documentation search with PDF ingestion, semantic chunking, Pinecone vector store, and a chat interface with citation tracking"

AI Agent Platform

"Design a multi-agent system where a supervisor agent delegates to specialist agents for code generation, research, and data analysis, with shared memory and tool access"

Customer Support Bot

"Design a production chatbot for e-commerce support with order lookup tools, return processing, FAQ retrieval, human escalation, and conversation analytics"

Content Generation Pipeline

"Design an AI content pipeline with topic research, outline generation, draft writing, fact-checking, SEO optimization, and human review workflow"

Frequently Asked Questions

How do I design a RAG system architecture?

Describe your RAG use case in InfraSketch (e.g., 'Design a RAG system for customer support with document ingestion, vector search, and response generation'). The AI generates a complete architecture with ingestion pipelines, chunking, embedding generation, vector database, retrieval, re-ranking, and generation components. Refine through chat to add specific components like metadata filtering or hybrid search.

What is the best tool for LLM application architecture?

InfraSketch is purpose-built for designing AI system architectures. Unlike general diagramming tools, InfraSketch understands LLM-specific components like vector databases, embedding models, prompt chains, and agent orchestration. It generates architectures from natural language and lets you refine through conversation.

Can I diagram multi-agent AI systems?

Yes. InfraSketch can generate architectures for multi-agent systems including supervisor patterns, peer-to-peer agent collaboration, hierarchical agent teams, and tool-calling workflows. Describe your agent system, and the AI creates a diagram showing agent interactions, shared state, tool integrations, and communication patterns.

How do I design a production chatbot architecture?

Describe your chatbot requirements (e.g., 'Design a customer service chatbot with conversation memory, tool calling for order lookups, content moderation, and analytics'). InfraSketch generates the full architecture including the LLM layer, conversation management, tool integration, guardrails, and monitoring. Then refine through chat to handle edge cases.

Does InfraSketch support LangGraph and LangChain architectures?

Yes. InfraSketch is itself built on LangGraph, so it deeply understands graph-based LLM orchestration patterns. You can design LangGraph state machines, LangChain pipelines, and custom orchestration architectures. The AI generates appropriate components for nodes, edges, conditional routing, and tool execution.
