A taste of what you will get

  • Your agent sends the same 6,000-token system prompt and tool definitions on every call. Which feature lowers cost and latency for that repeated prefix?

    • Raising temperature
    • Prompt caching
    • Model distillation only
    • Disabling streaming

    Answer: Prompt caching. Prompt caching reuses a stable prefix at a reduced rate and with lower latency on cache hits. Temperature and streaming do not change what you pay for repeated input.

  • A nightly job summarises 200,000 documents and nobody is waiting for results. Which option is typically cheapest?

    • Bedrock batch inference reading from S3
    • Provisioned Throughput with a six-month commitment
    • Streaming each response
    • On-demand calls in a tight loop

    Answer: Bedrock batch inference reading from S3. Batch inference processes prompts asynchronously at a discounted price versus on-demand for supported models. Provisioned Throughput pays for idle capacity and streaming adds nothing to an offline job.
