Sources

1. Bedrock model card: https://us-east-2.console.aws.amazon.com/bedrock/home?region=us-east-2#/model-catalog/nvidia.nemotron-super-3-120b
2. Bedrock models-at-a-glance: https://docs.aws.amazon.com/bedrock/latest/userguide/models-at-a-glance.html (lists model under NVIDIA provider)
3. Bedrock pricing page: https://aws.amazon.com/bedrock/pricing/ (NVIDIA section not visible in page scrape due to truncation — pricing needs manual verification)

Verification checklist

• Model ID confirmed in ≥2 independent official sources (model card + models-at-a-glance)
• Model ID format matches Bedrock convention
• Not already present in model_list.json (confirmed via grep)
• Standard/on-demand tier confirmed (not custom-deployment-only)
• Pricing needs manual verification from Bedrock pricing page
