This article details how to implement access control and cost monitoring for Large Language Models (LLMs) on AWS Bedrock using IAM. The author explains how to create an IAM user with a specific policy that restricts access to only four designated LLM models, namely qwen.qwen3-vl-235b-a22b, google.gemma-3-4b-it, google.gemma-3-12b-it, and google.gemma-3-27b-it. Additionally, it covers setting up cost tracking by tagging the IAM user, which allows for cost allocation and grouping in AWS Cost Explorer, noting that the tag needs to be activated for billing data and is not retroactive.
