Accesso API diretto ai modelli di OpenAI per creare funzionalità AI personalizzate.
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.

Pick this tier: 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.
What works
- 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
What to watch
- 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
Skip it if
- 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
