About ChatGPT API pricing
ChatGPT API pricing is set by OpenAI and billed per million tokens processed. Input tokens (your prompt) and output tokens (the response) are priced separately. Cached input pricing applies when the same context is reused across requests, offering significant savings for repeated prompts. Batch pricing is available for non-real-time workloads and typically offers up to 50% savings over standard rates.
