This vendor-neutral guide presents a three-agent system on AWS Bedrock AgentCore using Llama 4, a HIPAA-compliant fine-tuned model for document redaction, and Qwen 3.8 Max for case routing. Early pilot results from a mid-sized county show a 40% reduction in response time and 30% cost savings, with full FedRAMP and state data residency compliance.
As of May 22, 2026 Government IT leaders are increasingly turning to multi-agent systems to automate citizen services such as benefits inquiry, document processing, and case assignment. This article presents a vendor-neutral, three-agent architecture designed for public sector needs, deployed on AWS Bedrock AgentCore . The system uses Llama 4 for intent classification, a HIPAA-compliant fine-tuned model for secure document redaction, and Qwen 3.8 Max for intelligent case routing. Early pilot results from a mid-sized county show a 40% reduction in response time and 30% cost savings per transaction , while maintaining full compliance with FedRAMP and state data residency requirements. Why Multi-Agent Systems Are Transforming Citizen Services Citizen service centers face mounting pressure to reduce wait times, handle growing volumes of benefits inquiries, and ensure accuracy in document pro
cessing. Traditional rule-based systems struggle with the complexity and nuance of natural language requests. Multi-agent systems offer a scalable solution by breaking down end-to-end tasks into specialized, collaborating agents. Each agent handles a distinct function—intent recognition, sensitive data handling, or routing—allowing for faster, more reliable outcomes. For government leaders, this means not only operational efficiency but also improved citizen satisfaction and compliance with strict regulatory frameworks. The Three-Agent Architecture: Intent Classification, Redaction, and Routing The proposed architecture consists of three autonomous agents orchestrated by AWS Bedrock AgentCore: - Agent 1 – Intent Classifier : Receives incoming citizen requests (e.g., "I need to check my SNAP balance" or "I want to apply for Medicaid") and classifies them into predefined service categories
. Powered by Llama 4, this agent extracts key parameters and passes the request to the next stage. - Agent 2 – Document Redactor : Handles any documents or personally identifiable information (PII) attached to the request. It uses a fine-tuned model trained on HIPAA-compliant redaction rules to remove sensitive data (names, Social Security numbers, medical conditions) while preserving the document's utility for downstream processes. - Agent 3 – Case Router : Receives the redacted request and associated metadata, then determines the appropriate department or caseworker. Using Qwen 3.8 Max, it matches the request to the right queue based on skill, workload, and jurisdiction, and triggers a response or case creation. All communication between agents flows through Bedrock AgentCore’s message bus, ensuring traceability and audit readiness. Model Selection: Llama 4 for Intent, HIPAA-Compliant
Redaction, and Qwen 3.8 Max for Routing Llama 4 for Intent Classification Meta’s Llama 4 (released April 2026) brings significant improvements in natural language understanding and instruction following. Its small-footprint variants (3B and 8B parameters) are ideal for real-time classification tasks with low latency. In our pilot, Llama 4 8B achieved over 95% accuracy on a held-out set of 50 citizen service intent types. Deployment on AWS Bedrock with the Llama 4 model ID provides a managed inference endpoint with built-in scaling. HIPAA-Compliant Fine-Tuned Model for Document Redaction For document redaction, we fine-tuned a publicly available base model (e.g., Mixtral 8x7B) on a curated dataset of government correspondence annotated with redaction labels. The fine-tuned model is designed to comply with HIPAA Safe Harbor standards, automatically removing 18 identifiers (names, dates, ad
dresses, etc.) with a measured F1 score of 0.96. To ensure data privacy, the model is hosted on a dedicated Bedrock endpoint in a VPC with no internet access, and all inference logs are encrypted at rest and in transit. This agent does not retain any document content beyond the inference window. Qwen 3.8 Max for Case Routing Alibaba Cloud’s Qwen 3.8 Max (released May 2026) is a 38-billion-parameter model optimized for decision-making and structured output generation. It excels at understanding context and routing tasks based on complex rules. In our architecture, Qwen 3.8 Max processes the redacted request along with department availability data (from an internal API) to determine the optimal assignment. The model’s ability to provide confidence scores and alternative routing options allows human supervisors to override when necessary. Qwen 3.8 Max is available on AWS Marketplace via the
model ID . Step-by-Step Deployment on Managed Cloud Infrastructure Deploying the multi-agent system on AWS Bedrock AgentCore involves the following steps: 1. Set up the foundation : Create an AWS account with appropriate IAM roles, enable Bedrock, and request access to the desired models (Llama 4 8
