Available Models

Amazon Nova Reelpromptfooconfig.nova-reel.yamlus-east-16s - 2min
Luma Ray 2promptfooconfig.luma-ray.yamlus-west-2 only5s or 9s

Prerequisites

Video generation requires additional AWS setup beyond standard Bedrock access.

1. Enable Model Access

Visit the AWS Bedrock Model Access page and enable:

  • Nova Reel: amazon.nova-reel-v1:1 (us-east-1)
  • Luma Ray 2: luma.ray-v2:0 (us-west-2)

2. Create S3 Bucket

Video outputs are written to S3. Create a bucket in the same region as your model:

bash
# For Nova Reel (us-east-1)
aws s3 mb s3://your-bucket-nova-reel --region us-east-1

# For Luma Ray 2 (us-west-2)
aws s3 mb s3://your-bucket-luma-ray --region us-west-2

3. Configure IAM Permissions

json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["bedrock:InvokeModel", "bedrock:StartAsyncInvoke", "bedrock:GetAsyncInvoke"],
      "Resource": [
        "arn:aws:bedrock:*:*:model/amazon.nova-reel-v1:1",
        "arn:aws:bedrock:*:*:model/luma.ray-v2:0"
      ]
    },
    {
      "Effect": "Allow",
      "Action": ["s3:PutObject", "s3:GetObject"],
      "Resource": "arn:aws:s3:::your-bucket/*"
    }
  ]
}

4. Install Dependencies

bash
npm install @aws-sdk/client-bedrock-runtime @aws-sdk/client-s3

Usage

Update s3OutputUri in the config file, then run:

bash
# Nova Reel
npx promptfoo@latest eval -c promptfooconfig.nova-reel.yaml

# Luma Ray 2
npx promptfoo@latest eval -c promptfooconfig.luma-ray.yaml
