Solution overview

Cropwise AI is built on an AWS architecture designed to address these challenges through scalability, maintainability, and security. The architecture is divided into two main components: the agent architecture and knowledge base architecture. This solution is also deployed by using the AWS Cloud Development Kit (AWS CDK), which is an open-source software development framework that defines cloud infrastructure in modern programming languages and provisions it through AWS CloudFormation.

Agent architecture

The following diagram illustrates the serverless agent architecture with standard authorization and real-time interaction, and an LLM agent layer using Amazon Bedrock Agents for multi-knowledge base and backend orchestration using API or Python executors. Domain-scoped agents enable code reuse across multiple agents.

Amazon Bedrock Agents offers several key benefits for Syngenta compared to other solutions like LangGraph:

Flexible model selection – Syngenta can access multiple state-of-the-art foundation models (FMs) like Anthropic’s Claude 3.5 Haiku and Sonnet, Meta Llama 3.1, and others, and can switch between these models without changing code. They can select the model that is accurate enough for a specific workflow and yet cost-effective.
Ease of deployment – It is seamlessly integrated with other AWS services and has a unified development and deployment workflow.
Enterprise-grade security – With the robust security infrastructure of AWS, Amazon Bedrock is in scope for common compliance standards, including ISO, SOC, and CSA STAR Level 2; is HIPAA eligible; and you can use Amazon Bedrock in compliance with the GDPR.
Scalability and integration – It allows for straightforward API integration with existing systems and has built-in support for orchestrating multiple actions. This enables Syngenta to effortlessly build and scale their AI application.

The agent architecture handles user interactions and processes data to deliver accurate recommendations. It uses the following AWS services:

Serverless computing with AWS Lambda – The architecture begins with AWS Lambda, which provides serverless computing power, allowing for automatic scaling based on workload demands. When custom processing tasks are required, such as invoking the Amazon Bedrock agent or integrating with various data sources, the Lambda function is triggered to run these tasks efficiently.
Lambda-based action groups – The Amazon Bedrock agent directs user queries to functional actions which may use API-connections to gather data for use in workflows from various sources, model integrations to generate recommendations using the gathered data, or Python executions to extract specific pieces of information relevant to a user’s workflow and aid in product comparisons.
Secure user and data management – User authentication and authorization are managed centrally and securely through Amazon Cognito. This service makes sure user identities and access rights are handled effectively, maintaining the confidentiality and security of the system. The user identity gets propagated over a secure side channel (session attributes) to the agent and action groups. This allows them to access user-specific or restricted information, whereas each access can be authorized within the workflow. The session attributes aren’t shared with the LLM, making sure that authorization decisions are done on validated and tamper-proof data. For more information about this approach, see Implement effective data authorization mechanisms to secure your data used in generative AI applications.
Real-time data synchronization with AWS AppSync – To make sure that users always have access to the most up-to-date information, the solution uses AWS AppSync. It facilitates real-time data synchronization and updates by using GraphQL APIs, providing seamless and responsive user experiences.
Efficient metadata storage with Amazon DynamoDB – To support quick and efficient data retrieval, document metadata is stored in Amazon DynamoDB. This NoSQL database is optimized for rapid access, making sure the knowledge base remains responsive and searchable.
Centralized logging and monitoring with Amazon CloudWatch – To maintain operational excellence, Amazon CloudWatch is employed for centralized logging and monitoring. It provides deep operational insights, aiding in troubleshooting, performance tuning, and making sure the system runs smoothly.

The architecture is designed for flexibility and resilience. AWS Lambda enables the seamless execution of various tasks, including data processing and API integration, and AWS AppSync provides real-time interaction and data flow between the user and the system. By using Amazon Cognito for authentication, the agent maintains confidentiality, protecting sensitive user data.

Knowledge base architecture

The following diagram illustrates the knowledge base architecture.

The knowledge base architecture focuses on processing and storing agronomic data, providing quick and reliable access to critical information. Key components include:

Orchestrated document processing with AWS Step Functions – The document processing workflow begins with AWS Step Functions, which orchestrates each step in the process. From the initial ingestion of documents to their final storage, Step Functions makes sure that data handling is seamless and efficient.
Automated text extraction with Amazon Textract – As documents are uploaded to Amazon Simple Storage Service (Amazon S3), Amazon Textract is triggered to automatically extract text from these documents. This extracted text is then available for further analysis and the creation of metadata, adding layout-based structure and meaning to the raw data.
Primary data storage with Amazon S3 – The processed documents, along with their associated metadata, are securely stored in Amazon S3. This service acts as the primary storage solution, providing consistent access and organized data management for all stored content.
Efficient metadata storage with DynamoDB – To support quick and efficient data retrieval, document metadata is stored in DynamoDB.
Amazon Bedrock Knowledge Bases – The final textual content and metadata information gets ingested into Amazon Bedrock Knowledge Bases for efficient retrieval during the agentic workflow, backed by an Amazon OpenSearch Service vector store. Agents can use one or multiple knowledge bases, depending on the context in which they are used.

This architecture enables comprehensive data management and retrieval, supporting the agent’s ability to deliver precise recommendations. By integrating Step Functions with Amazon Textract, the system automates document processing, reducing manual intervention and improving efficiency.

Use cases

Cropwise AI addresses several critical use cases, providing tangible benefits to sales representatives and growers:

Product recommendation – A sales representative or grower seeks advice on the best seed choices for specific environmental conditions, such as “My region is very dry and windy. What corn hybrids do you suggest for my field?”. The agent uses natural language processing (NLP) to understand the query and uses underlying agronomy models to recommend optimal seed choices tailored to specific field conditions and agronomic needs. By integrating multiple data sources and explainable research results, including weather patterns and soil data, the agent delivers personalized and context-aware recommendations.
Querying agronomic models – A grower has questions about plant density or other agronomic factors affecting yield, such as “What are the yields I can expect with different seeding rates for corn hybrid G11V76?” The agent interprets the query, accesses the appropriate agronomy model, and provides a simple explanation that is straightforward for the grower to understand. This empowers growers to make informed decisions based on scientific insights, enhancing crop management strategies.
Integration of multiple data sources – A grower can ask for a recommendation that considers real-time data like current weather conditions or market prices, such as “Is it a good time to apply herbicides to my corn field?” The agent pulls data from various sources, integrates it with existing agronomy models, and provides a recommendation that accounts for current conditions. This holistic approach makes sure that recommendations are timely, relevant, and actionable.
