GPT 5 Nano API Frequently Asked Questions
Find answers about the gpt 5 nano api, including pricing, performance, multimodal features, and how to integrate it into your production apps.
What is the typical latency of the gpt 5 nano api?
The gpt 5 nano api is built for speed, achieving a sub-100ms time-to-first-token. Internal benchmarks show it is 40% faster than the previous gpt 4o-mini tier, making it ideal for gpt-powered real-time applications.
Does gpt 5 nano support native audio processing?
Yes, unlike earlier small gpt models, gpt 5 nano processes audio inputs directly. This gpt 5 nano api capability preserves emotional prosody and ambient context without requiring an extra gpt transcription step.
How much does the gpt 5 nano api cost per token?
Pricing for the gpt 5 nano api is extremely competitive at $0.05 per 1M input tokens and $0.20 per 1M output tokens. This gpt tier also offers 50% discounts for cached gpt inputs and batch processing via our gpt API.
Is the gpt 5 nano api good for structured data?
The gpt 5 nano api is optimized for structured output, outperforming competitors like Llama in complex JSON extraction. It reliably triggers up to 10 parallel tool calls in a single gpt turn without losing accuracy.
What is the context window for gpt 5 nano?
This gpt 5 nano api provides a 128,000 token context window. While it handles large gpt prompts efficiently, it is most accurate when the gpt target information is clearly defined within the conversation flow.
How do I migrate my app to the gpt 5 nano api?
Migrating to the gpt 5 nano api is simple. Just update the model parameter to gpt-5-nano in your gpt code. The gpt 5 nano api is 100% backward compatible with existing gpt SDKs and schemas.
