Organizations face the challenge to manage data, multiple artificial intelligence and machine learning (AI/ML) tools, and workflows across different environments, impacting productivity and governance. A unified development environment consolidates data processing, model development, and AI application deployment into a single system. This integration streamlines workflows, enhances collaboration, and accelerates AI solution development from concept to production.

The next generation of Amazon SageMaker is the center for your data, analytics, and AI. SageMaker brings together AWS AI/ML and analytics capabilities and delivers an integrated experience for analytics and AI with unified access to data. Amazon SageMaker Unified Studio is a single data and AI development environment where you can find and access your data and act on it using AWS analytics and AI/ML services, for SQL analytics, data processing, model development, and generative AI application development.

With SageMaker Unified Studio, you can efficiently build generative AI applications in a trusted and secure environment using Amazon Bedrock. You can choose from a selection of high-performing foundation models (FMs) and advanced customization and tooling such as Amazon Bedrock Knowledge Bases, Amazon Bedrock Guardrails, Amazon Bedrock Agents, and Amazon Bedrock Flows. You can rapidly tailor and deploy generative AI applications, and share with the built-in catalog for discovery.

In this post, we demonstrate how you can use SageMaker Unified Studio to create complex AI workflows using Amazon Bedrock Flows.

Solution overview

Consider FinAssist Corp, a leading financial institution developing a generative AI-powered agent support application. The solution offers the following key features:

  • Complaint reference system – An AI-powered system providing quick access to historical complaint data, enabling customer service representatives to efficiently handle customer follow-ups, support internal audits, and aid in training new staff.
  • Intelligent knowledge base – A comprehensive data source of resolved complaints that quickly retrieves relevant complaint details, resolution actions, and outcome summaries.
  • Streamlined workflow management – Enhanced consistency in customer communications through standardized access to past case information, supporting compliance checks and process improvement initiatives.
  • Flexible query capability – A straightforward interface supporting various query scenarios, from customer inquiries about past resolutions to internal reviews of complaint handling procedures.

Let’s explore how SageMaker Unified Studio and Amazon Bedrock Flows, integrated with Amazon Bedrock Knowledge Bases and Amazon Bedrock Agents, address these challenges by creating an AI-powered complaint reference system. The following diagram illustrates the solution architecture.

The solution uses the following key components:

  • SageMaker Unified Studio – Provides the development environment
  • Flow app – Orchestrates the workflow, including:
    • Knowledge base queries
    • Prompt-based classification
    • Conditional routing
    • Agent-based response generation

The workflow processes user queries through the following steps:

  1. A user submits a complaint-related question.
  2. The knowledge base provides relevant complaint information.
  3. The prompt classifies if the query is about resolution timing.
  4. Based on the classification using the condition, the application takes the following action:
    1. Routes the query to an AI agent for specific resolution responses.
    2. Returns general complaint information.
  5. The application generates an appropriate response for the user.

Prerequisites

For this example, you need the following:

  • Access to SageMaker Unified Studio. (You will need the SageMaker Unified Studio portal URL from your administrator). You can authenticate using either:
  • The IAM user or IAM Identity Center user must have appropriate permissions for:
    • SageMaker Unified Studio.
    • Amazon Bedrock (including Amazon Bedrock Flows, Amazon Bedrock Agents, Amazon Bedrock Prompt Management, and Amazon Bedrock Knowledge Bases).
    • For more information, refer to Identity-based policy examples.
  • Access to Amazon Bedrock FMs (make sure these are enabled for your account), for example:Anthropic’s Claude 3 Haiku (for the agent).
  • Configure access to your Amazon Bedrock serverless models for Amazon Bedrock in SageMaker Unified Studio projects.
  • Amazon Titan Embedding (for the knowledge base).
  • Sample complaint data prepared in CSV format for creating the knowledge base.

Prepare your data

We have created a sample dataset to use for Amazon Bedrock Knowledge Bases. This dataset has information of complaints received by customer service representatives and resolution information.The following is an example from the sample dataset:

T: If the input contains information about complaint resolution timing, response time, or processing timeline (whether timely or delayed)
F: For all other types of complaint information
Return only 'T' or 'F' based on whether the knowledge base response is about resolution timing. Do not add any additional text or explanation - respond with just the single letter 'T' or 'F'.

  1. Choose Save.

  1. Choose Create version.

Create a chat agent

Let’s create a chat agent to handle specific resolution responses. Complete the following steps:

  1. In SageMaker Unified Studio, on the Build menu, choose Chat agent under Machine Learning & Generative AI.
  2. Provide a name for the prompt.
  3. Choose the appropriate FM (for this example, we choose Claude 3 Haiku).
  4. For Enter a system prompt, we enter the following:
You are a Financial Complaints Assistant AI. You will receive complaint information from a knowledge base and questions about resolution timing.
When responding to resolution timing queries:
1. Use the provided complaint information to confirm if it was resolved within timeline
2. For timely resolutions, provide:
   - Confirmation of timely completion
   - Specific actions taken (from the provided complaint data)
   - Next steps that were completed
2. For delayed resolutions, provide:
   - Acknowledgment of delay
   - Standard compensation package:
     • $75 service credit
     • Priority Status upgrade for 6 months
     • Service fees waived for current billing cycle
   - Actions taken (from the provided complaint data)
   - Contact information for follow-up: Priority Line: **************

  1. Choose Save.

  1. After the agent is saved, choose Deploy.
  2. For Alias name, enter demoAlias.
  3. Choose Deploy.

Create a flow

Now that we have our prompt and agent ready, let’s create a flow that will orchestrate the complaint handling process:

  1. In SageMaker Unified Studio, on the Build menu, choose Flow under Machine Learning & Generative AI.

  1. Create a new flow called demo-flow.

Add a knowledge base to your flow application

Complete the following steps to add a knowledge base node to the flow:

  1. In the navigation pane, on the Nodes tab, choose Knowledge Base.
  2. On the Configure tab, provide the following information:
    1. For Node name, enter a name (for example, complaints_kb).
    2. Choose Create new Knowledge Base.
  3. In the Create Knowledge Base pane, enter the following information:
    1. For Name, enter a name (for example, complaints).
    2. For Description, enter a description (for example, user complaints information).
    3. For Add data sources, select Local file and upload the complaints.txt file.
    4. For Embeddings model, choose Titan Text Embeddings V2.
    5. For Vector store, choose OpenSearch Serverless.
    6. Choose Create.

  1. After you create the knowledge base, choose it in the flow.
  2. In the details name, provide the following information:
  3. For Response generation model, choose Claude 3 Haiku.
  4. Connect the output of the flow input node with the input of the knowledge base node.
  5. Connect the output of the knowledge base node with the input of the flow output node.

  1. Choose Save.

Add a prompt to your flow application

Now let’s add the prompt you created earlier to the flow:

  1. On the Nodes tab in the Flow app builder pane, add a prompt node.
  2. On the Configure tab for the prompt node, provide the following information:
  3. For Node name, enter a name (for example, demo_prompt).
  4. For Prompt, choose financeAssistantPrompt.
  5. For Version, choose 1.
  6. Connect the output of the knowledge base node with the input of the prompt node.
  7. Choose Save.

Add a condition to your flow application

The condition node determines how the flow handles different types of queries. It evaluates whether a query is about resolution timing or general complaint information, enabling the flow to route the query appropriately. When a query is about resolution timing, it will be directed to the chat agent for specialized handling; otherwise, it will receive a direct response from the knowledge base. Complete the following steps to add a condition:

  1. On the Nodes tab in the Flow app builder pane, add a condition node.
  2. On the Configure tab for the condition node, provide the following information:
    1. For Node name, enter a name (for example, demo_condition).
    2. Under Conditions, for Condition, enter conditionInput == "T".
    3. Connect the output of the prompt node with the input of the condition node.
  3. Choose Save.

Add a chat agent to your flow application

Now let’s add the chat agent you created earlier to the flow:

  1. On the Nodes tab in the Flow app builder pane, add the agent node.
  2. On the Configure tab for the agent node, provide the following information:
    1. For Node name, enter a name (for example, demo_agent).
    2. For Chat agent, choose DemoAgent.
    3. For Alias, choose demoAlias.
  3. Create the following node connections:
    1. Connect the input of the condition node (demo_condition) to the output of the prompt node (demo_prompt).
    2. Connect the output of the condition node:
      1. Set If condition is true to the agent node (demo_agent).
      2. Set If condition is false to the existing flow output node (FlowOutputNode).
    3. Connect the output of the knowledge base node (complaints_kb) to the input of the following:
      1. The agent node (demo_agent).
      2. The flow output node (FlowOutputNode).
    4. Connect the output of the agent node (demo_agent) to a new flow output node named FlowOutputNode_2.
  4. Choose Save.

Test the flow application

Now that the flow application is ready, let’s test it. On the right side of the page, choose the expand icon to open the Test pane.

In the Enter prompt text box, we can ask a few questions related to the dataset created earlier. The following screenshots show some examples.

Clean up

To clean up your resources, delete the flow, agent, prompt, knowledge base, and associated OpenSearch Serverless resources.
