OpenAI API 定价
面向技术团队OpenAI API 按使用量而非按月定价；每种选项的费率见下表。 已于 2026年11月10日 对照官方定价页面核对。
直接 API 访问 OpenAI 的模型，用于构建自定义 AI 功能。
The OpenAI API is the default choice for adding AI features to your own product: broad model range, mature tooling and several service tiers that trade speed for price. It is priced per token, so what it costs depends on your model choice and how much you cache.

选择这一档：API (pay-as-you-go)
There is one pay-as-you-go account; the saving comes from choosing the smallest model that does the job and using Batch or Flex for anything not user-facing.
优点
- Wide range of model sizes, from low-cost small models to flagships
- Batch and Flex tiers cut cost for work that can wait
- Large discount on cached input
- Mature tool calling and long-context support
注意事项
- Per-token pricing makes monthly cost hard to predict without testing
- Long prompts past the short-context threshold bill at higher rates
- Regional data-residency endpoints cost more
以下情况可跳过
- You want a chat app rather than an API
- Nobody on the team can write code
- You need the lowest possible cost per token above everything else

- Is the OpenAI API included with ChatGPT Plus?
- No. The API is billed separately, per token, on its own account. ChatGPT subscriptions do not include API usage.
- How can I lower OpenAI API costs?
- Use the smallest model that works, reuse prompts so cached-input pricing applies, and send non-urgent jobs through the Batch or Flex tiers, which OpenAI prices at roughly half of Standard.
