Pricing Modes

On-Demand

• Pay-as-you-go → no long-term commitment
  • great for unpredictable workloads
• ‼️ Works with Base Models only!
• Model charges:
  • Text Models – charged for every input/output token processed
  • Embedding Models – charged for every input token processed
  • Image Models – charged for every image generated

Batch

• Multiple predictions at a time, output is a single file in S3
• Discounts of up to 50%
• 💡 Answers to prompts are no longer in real time, but can get significant discounts

Provisioned Throughput

• Reserves throughput/capacity for a certain time (1 month, 6 months…)
• Throughput = max number of input/output tokens processed per minute
• ‼️ Required for Fine-tuned and Custom Models!
  • Base Models can also use provisioned throughput, but not required

Other cost considerations

• Number of input & output tokens → main driver of cost
• Model size → usually a smaller model is cheaper
  • Varies based on providers
  • Smaller models also have less capabilities and capacity
