BMW Group builds CLEAI, a generative AI assistant for cloud cost optimization on AWS
BMW Group· GermanyAmazon Bedrock · Amazon Bedrock Knowledge Bases · Amazon OpenSearch Serverless +4BMW Group's FinOps Center of Excellence, with AWS Professional Services, built CLEAI, a generative AI assistant inside its CLEA cloud cost tool. Users ask in natural language about cloud costs and metadata, get optimization recommendations drawn from AWS documentation and BMW's internal FinOps knowledge base (RAG with Amazon Bedrock Knowledge Bases), and get generated Terraform, CLI and Python code. The source states it supports more than five thousand users and speeds up analysis and implementation by up to 50%.

Inspect the highlighted sourceThe challenge
BMW Group's cloud environment grew from 4,500 AWS accounts in 2023 to over 10,000 in 2025. Navigating complex cloud environments to understand costs and resource usage can be a significant bottleneck.
The solution
BMW Group's FinOps Center of Excellence partnered with AWS Professional Services to build CLEAI, a generative AI assistant integrated into its CLEA cloud cost tool. It uses several specialized LLM chains (API, conversational, clarify and retrieval) behind an intent classifier. The retrieval chain runs RAG on an Amazon Bedrock Knowledge Bases setup with Amazon OpenSearch Serverless as vector store, populated with AWS best practices and BMW Group internal information. Users ask in natural language and also get generated Terraform, CLI commands and Python scripts.
Reported business value
The source states CLEAI supports more than five thousand BMW Group users and accelerates analysis and implementation of cloud infrastructure optimization by up to 50%.
