What is Generative AI on AWS?
Generative AI on AWS is the set of managed services that lets organizations build, deploy, and operate large language model (LLM) and foundation-model applications without managing GPU infrastructure. The stack centers on Amazon Bedrock for foundation models (Claude Fable 5.1 for long-horizon Covered Model jobs, Claude Opus 5.5 with ZDR default and 1M context, Claude Opus 5 as the prior Opus pin, Claude Sonnet 5, Claude Haiku 5.5 (Haiku 4.5 remains the prior pin), Amazon Nova 2 Lite, OpenAI GPT-6 Astra / Sol / Luna with GPT-5.6 as the prior pins, xAI Grok 4.6 with US Geo / Global CRIS, Grok 4.3, Llama, Mistral Large 3, Cohere, and marketplace models including GLM 5.3 (October 5, 2026 — eligible customers, US/Global CRIS, 1M context; GLM 5 remains the prior pin) and MiniMax M2.5), Amazon SageMaker AI / Unified Studio for custom training and hosting, and Amazon Q / Quick Suite for turnkey assistants — all integrated with VPC endpoints, IAM, KMS, and CloudTrail for data residency and audit-ready compliance.

The AWS Generative AI Stack
AWS provides the most complete enterprise-ready stack for generative AI — from managed model access to data pipelines, vector search, orchestration, and guardrails.
Bedrock vs SageMaker vs Amazon Q — Decision Matrix
The key services:
Amazon Bedrock
Amazon Bedrock is the starting point for most enterprise GenAI on AWS. It provides serverless access to foundation models from Anthropic (Claude), Meta (Llama), Mistral, Cohere, OpenAI, xAI, and Amazon (Nova, plus Titan embeddings) through a single API — without provisioning or managing any model infrastructure.
Bedrock includes:
- Model invocation — Single API for text generation, embeddings, image generation across all providers
- Bedrock Knowledge Bases — Managed RAG infrastructure with automatic chunking, embedding, and vector storage
- Bedrock Agents — Orchestration framework for multi-step AI agents that use tools and take actions
- Bedrock Guardrails — Content filtering, PII detection, topic restrictions, and grounding checks
- Model evaluation — Side-by-side comparison of models against your data before committing
- Bedrock Prompt Caching — Cuts input token costs 70–90% and latency 60–85% on workloads with stable system prompts or repeated knowledge-base context
- Bedrock Marketplace & Custom Model Import — 100+ models including third-party and your own fine-tuned weights, deployed on managed Bedrock infrastructure
- Bedrock Flows & AgentCore — Visual workflow builder plus a durable agent runtime. AgentCore Managed Harness (April 2026) handles deployment, scaling, and security for agentic workloads; Policy controls (GA March 2026) verify what actions agents can take before they reach tools or data
- Bedrock Managed Agents (OpenAI) — Limited-preview managed agents powered by OpenAI frontier models, combining GPT-5-class reasoning with AWS infrastructure and governance
Amazon SageMaker
SageMaker is the platform for teams that need to go beyond off-the-shelf foundation models:
- Fine-tuning — Domain-specific customization of foundation models on your data
- Model hosting — Deploy custom or fine-tuned models with auto-scaling endpoints
- SageMaker Pipelines — Automated ML workflows for training, evaluation, and deployment
- Feature Store — Centralized feature management for ML applications
- SageMaker Unified Studio — Single workspace for data preparation, model development, and GenAI app building with shared governance
Amazon Q
Amazon Q extends generative AI capabilities to specific AWS use cases:
- Amazon Q Business — Enterprise assistant connected to your internal knowledge base (SharePoint, Confluence, Salesforce, S3)
- Amazon Q Developer — AI coding assistant for AWS development tasks, integrated into IDEs and the CLI
- Amazon Q for QuickSight — Natural language interface for BI dashboards
- Amazon Q Apps — User-built workflows on top of Q Business (no-code, ACL-aware)
- Amazon Q in Connect — Real-time agent assistance for contact centers on Amazon Connect
What We Build
Internal Knowledge Assistants
Enterprise chatbots that answer questions from your internal documentation, Confluence, SharePoint, Slack archives, and database records. Powered by Bedrock Knowledge Bases with Kendra or OpenSearch as the retrieval layer.
Example: A healthcare company’s internal assistant answering clinical protocol questions from 50,000 pages of documentation — with citations and source links, deployed with HIPAA-compliant architecture on Bedrock.
Document Intelligence
Applications that read, extract, classify, and summarize large volumes of documents — contracts, medical records, financial reports, regulatory filings.
Components: Textract for extraction, Bedrock Claude for summarization and classification, S3 for storage, Lambda for orchestration.
Example: A fintech operations team automating SOC 2 evidence collection from 12,000 quarterly documents — Textract → Bedrock classification → S3 evidence locker, audit log every step. Replaced 3 FTE-weeks of manual review per quarter.
AI Customer Support
Customer-facing support automation that handles common inquiries, escalates complex cases, and provides agents with suggested responses — grounded in your product documentation and customer history.
Code Generation & Review Workflows
Developer tooling that accelerates code review, generates boilerplate, writes tests, and explains complex codebases — integrated with your CI/CD pipeline and built on Amazon Q Developer or Bedrock.
Predictive Analytics with GenAI
Combining SageMaker for predictive models with Bedrock for natural language explanation of predictions — enabling business users to understand model outputs without data science expertise.
Example: A retail operations team running a SageMaker demand-forecast model for 800 SKUs, with Bedrock generating plain-language explanations of week-over-week shifts (“inventory at risk at 12 stores due to promo cannibalization”) for store managers who do not read statistical output.
Our GenAI Delivery Process
Phase 1: Discovery (Week 1)
- Use case scoping and feasibility assessment
- Data audit — what private data exists, in what format, and how it must be protected
- Architecture selection — Bedrock vs. SageMaker, RAG vs. fine-tuning, vector store selection
- Compliance requirements mapping (HIPAA, SOC 2, PCI DSS if applicable)
Phase 2: Prototype (Weeks 2–3)
- Core application built with real data
- Model selection and evaluation
- RAG pipeline configuration and retrieval quality testing
- Initial guardrails implementation
Phase 3: Productionize (Weeks 4–8)
- Authentication and authorization integration
- Observability (CloudWatch metrics, request/response logging)
- Cost controls and model invocation budget alerts
- Guardrails hardening and adversarial testing
- Load testing and latency optimization
- CI/CD pipeline for model prompt versioning and deployment
Phase 4: Monitor & Improve
- Response quality monitoring
- Retrieval relevance tracking
- Model version upgrades as new foundation models release
- Continuous improvement based on user feedback
Security & Governance
Enterprise generative AI requires more than just good prompts:
- Data isolation — All components deployed within your VPC. No data leaves your AWS environment.
- Model access control — IAM policies restrict which roles and services can invoke models
- Audit logging — Every model invocation logged to CloudTrail with user identity and request context
- Guardrails — Bedrock Guardrails for content filtering, PII protection, and topic restrictions
- Prompt injection protection — Input validation and system prompt hardening
- Cost guardrails — Per-model and per-user invocation budgets with alerts
