Frequently asked
GPT-5 Nano is a lightweight language model from the GPT-5 family designed for rapid text generation with low latency and cost-effective performance, ideal for real-time applications.
GPT-5 Nano is optimized for high-speed text generation, making it exceptionally suited for applications such as chatbots and real-time content processing.
No, including an image URL is optional. The primary requirement is the `prompt` field, which drives the text generation process.
With a cost of $0.01 per generation, GPT-5 Nano offers one of the most affordable pricing options in the market while maintaining superior quality and performance.
Yes. Prompt Caching allows you to reuse frequently used text prompts at reduced rates. Cache hits (reusing previously cached tokens) are charged at 0.1x of the input cost. New cache creation (writing new tokens to cache for future reuse) is charged at 1.25x of the standard input cost.
