Direct API access to OpenAI's models for building custom AI features.
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.

選擇此等級：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.
表現良好之處
- 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
需要留意之處
- 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
以下情況可略過
- 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

- 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.
