AWS AgentCore deck generator sample: ~$0.04 and 70–90 seconds

An AWS reference build turns a 90-page report into a six-slide PowerPoint in 70–90 seconds for about $0.04, but reports no accuracy check.

Amazon Web Services published a technical how-to on 14 October 2026, written by three AWS Professional Services staff, for a system that generates client PowerPoint decks from enterprise documents. The authors use a financial-services team as the example, one that spends hours each week turning quarterly reports and compliance documents into slides. The post is vendor-published: AWS sells every service in the stack.

What is in the build

A single supervisor agent runs on Amazon Bedrock AgentCore runtime using the open source Strands Agents framework. It has two tools: one that generates a PowerPoint file and one that summarises the knowledge base. Documents sit in Amazon S3 and are chunked, embedded with Amazon Titan Text Embeddings v2 and stored in Amazon OpenSearch Serverless. Anthropic Claude Sonnet 4.6 writes the content, Claude Haiku 4.5 is the suggested model for parsing documents, and Stability AI Stable Image Inpaint makes slide images.

Around the agent sit a .NET 8 chat API on AWS Lambda, Amazon API Gateway, Amazon Cognito, AWS WAF, Amazon Bedrock Guardrails for input, output and personal-data handling, and a separate tenant role per customer. AWS provides the code as a public sample repository and a CDK deployment in three phases.

The numbers, from AWS's own test

  • Input: a 90-page Amazon 2024 annual report PDF.
  • Output: six slides, with two AI-generated images, speaker notes and corporate template formatting.
  • Time: 70–90 seconds end to end, which is longer than API Gateway's default 29-second limit, so the chat API runs asynchronously and the caller must stream or poll.
  • Cost: about $0.04 per generation in model invocation charges at time of writing in us-east-1, with image generation most of it. The post gives no figure for Lambda, OpenSearch Serverless or the other services.

What the post leaves out

It tests one document and reports no accuracy figure: no check that numbers on slides match the report, no hallucination rate and no count of slides a person had to fix. It says the retrieval design is meant to help reduce hallucinated content, which is a design intent, not a result. It also gives no always-on cost, and an OpenSearch Serverless collection bills while it exists.

One caveat is stated plainly. The OpenSearch Serverless collection's data plane must stay publicly reachable, because Bedrock Knowledge Bases connects from AWS-managed infrastructure; IAM data access policies protect it. A security review should read that note before approval.

What a team can take from it

Treat the $0.04 as a floor for one small deck, not a budget. If you try the pattern, run it on documents where you already know the right numbers, compare every figure on every slide, and measure the time your staff spend correcting a deck against the hours it replaced. That comparison is the number the post does not give.

If a model drafts client decks from your internal reports, what check would you require on the figures before a deck leaves the building?

The short version
  • AWS authors say a sample supervisor agent on Amazon Bedrock AgentCore, with Claude Sonnet 4.6 and a retrieval pipeline over your documents, builds a six-slide PowerPoint in 70–90 seconds.
  • In AWS's internal test on a 90-page Amazon 2024 annual report the model cost was about $0.04 per deck in us-east-1, most of it image generation, and ingesting a 1.3 MB PDF took under 2 minutes.
  • The post reports one test document and no measure of whether the slides are accurate, so check grounding on your own documents before any client sees a generated deck.

Questions this article answers

What does the AWS AgentCore PowerPoint generator sample do?

AWS says it uses a supervisor agent on Amazon Bedrock AgentCore with retrieval over uploaded documents to generate a PowerPoint deck, or a summary, grounded in those documents.

How much does it cost to generate a presentation with the AWS sample?

AWS reports about $0.04 per generation in model invocation costs in us-east-1 at the time of writing, mostly for image generation. It does not price the other AWS services.

How long does the AWS sample take to generate a deck?

In AWS's internal test on a 90-page annual report it took 70–90 seconds for a six-slide deck, so the API must run asynchronously.

Does the post measure whether the slides are accurate?

No. It reports timing and cost on one test document and says retrieval is designed to help reduce hallucinated content, but gives no accuracy result.
