Optimization Suggestions

General cost-saving tactics

  • Enable prompt caching for repeated system prompts / long context — can cut input costs by up to 90% on cache hits.
  • Use the Batch API for non-latency-sensitive workloads for roughly 50% off standard pricing.
  • Cap max_tokens and trim system prompts to reduce output-side overspend on chatty responses.
  • Route simple/classification tasks to a smaller model and reserve flagship models for complex reasoning.
  • Set hard spend alerts at 50% / 75% / 90% of budget so you catch drift before it compounds.
