In January 2026, John Moul contributed to the aws-samples/amazon-nova-samples repository by enhancing the Reinforcement Fine-Tuning (RFT) evaluation pipeline for Amazon Nova models. He developed a notebook-driven workflow for RFT evaluation, refining the rft_eval recipe and improving configuration management to increase automation and reliability. John also implemented an AWS Lambda function leveraging Amazon Bedrock to automate response similarity scoring, streamlining the RFTEvalInvoker process. His work involved Python, AWS Lambda, and Boto3, with careful attention to JSON handling and documentation cleanup. These contributions deepened the evaluation pipeline’s robustness and consistency, supporting more reliable model assessment and deployment practices.
