  - Provides lower costs for requests in exchange for slower response times and occasional resource unavailability. Ideal for non-production or lower priority tasks.
  - Enterprise offerings
  - Contact our sales team to learn more about Data residency⁠(opens in a new window), Scale Tier⁠ andReserved Capacity⁠ designed for cutting-edge customers running larger workloads.
  - We recommend experimenting with all of these models in the Playground⁠⁠(opens in a new window) to explore which models provide the best price performance trade-off for your usage.
  - Do you offer an enterprise package or SLAs?
  - We offer different tiers of access to our enterprise customers that include SLAs, lower latency, and more. Please contact our sales team⁠ to learn more.
  - Yes, we treat Playground usage the same as regular API usage. You will be billed at the per-token input and output prices mentioned above.
  - How will I know how many tokens I’ve used each month?
  - A token is a mathematical representation of natural language. Log in to your account to view your usage tracking dashboard⁠(opens in a new window). This dashboard will show you how many tokens you’ve used during the current and past billing cycles.
  - You can set a monthly budget in your billing settings⁠⁠(opens in a new window), after which we’ll stop serving your requests. There may be a delay in enforcing the limit, and you are responsible for any overage incurred. You can also configure an email notification threshold to receive an email alert once you cross that threshold each month. We recommend checking your usage tracking dashboard⁠(opens in a new window) regularly to monitor your spend.
  - Is access to the API included in ChatGPT Plus, Business, Enterprise or Edu?
  - No, OpenAI APIs are billed separately from ChatGPT Plus, Business, Enterprise and Edu. ChatGPT subscription pricing can be found at openai.com/chatgpt/pricing/⁠.
  - Images are converted into tokens and charged per token. Text models price image tokens at standard text token rates, while GPT Image and gpt-realtime uses a separate image token rate. Models like gpt-4.1-mini, gpt-4.1-nano, and o4-mini convert images into tokens differently. Learn more in our docs⁠(opens in a new window).
