What Makes Forecast Powerful
Forecast Pricing & Free Tier
SageMaker: from ~$0.045/hour for ml.t3.medium instances. Bedrock: on-demand per-token pricing. Rekognition: $1 per 1,000 images (first 5,000 free).
Forecast Best Practices
- 1Start with pre-trained models (Bedrock, Rekognition) before training custom models
- 2Use SageMaker Experiments to track training runs, hyperparameters, and metrics
- 3Enable Model Monitor to detect data drift in production endpoints
- 4Set up cost allocation tags on training jobs — GPUs are expensive if left running
- 5Clean up unused endpoints — they incur hourly charges even with zero traffic
