Cost field

usage.cost is the amount charged for this call (in USD); in streaming it arrives on the final chunk that carries usage. OpenAI SDKs ignore this extra field.

#프롬프트 캐싱

This model uses automatic (implicit) caching — repeated prompt prefixes are cached upstream automatically and billed at a lower rate, with no parameters needed (no cache_control). Keep long, stable context (system prompt, tools) at the start of your messages to get hits.

Automatic — nothing to do

Cache hits show up in the returned usage (cached tokens) and your cost drops automatically.

#사고

지원 모델에서는 reasoning_effort(low / medium / high)를 추가하세요. 사고 내용은 응답의 reasoning_content 필드로 반환되며, 사고 토큰은 출력 요금으로 청구됩니다.
