What challenges did Toyota face before AI implementation?

Rapid engineering changes and expanding vehicle complexity increased the number of items to be developed. Retiring engineers risked taking critical expertise and design knowledge with them.

What was the impact of the AI solution?

800 engineers have access to O-Beya. The system has been used hundreds of times a month. It makes information easier to find and helps transfer knowledge to the next generation.

Toyota deploys Microsoft Azure OpenAI Agent System 'O-Beya' to accelerate engineering innovation

Use case typeKnowledge managementUpdated Nov 19, 2024

Toyota is building a system of generative AI agents at headquarters in Toyota City to store and share internal expertise and help develop new vehicle models faster. The system, named O-Beya, combines specialized agents and uses Microsoft Azure OpenAI Service, GPT-4o, Azure Functions, and Azure Cosmos DB with Toyota’s engineering, design, and regulatory data.

Rapid engineering changes and expanding vehicle complexity increased the number of items to be developed.
Retiring engineers risked taking critical expertise and design knowledge with them.

Built a generative AI agent system called O-Beya with nine specialized agents.
Used Azure OpenAI Service, GPT-4o, Azure Functions, and Azure Cosmos DB for vector search, orchestration, and secure storage of conversation histories and human reviews.
Grounded the system in Toyota design reports, regulatory information, and handwritten documents from veteran engineers.

Architecture

O-Beya is a multi-agent system with nine specialized AI agents. It is built on Azure OpenAI Service and GPT-4o, with Azure Functions connecting the AI service to Azure Cosmos DB for vector search, secure conversation history storage, and human review feedback loops. The system uses Toyota design reports, regulatory documents, and handwritten engineer notes as grounded context, and future plans include adding non-text data such as technical drawings.
