Frequently asked questions

How much does it cost to use OpenAI: GPT-5 Nano?

OpenAI: GPT-5 Nano is a Pro model: it costs 10 tokens per use (~$0.05 real cost for us). You need a Pro plan ($9/month → 15,000 tokens) or a one-shot pack. If you already have tokens in the free account, you can also spend them directly.

How many OpenAI: GPT-5 Nano uses are included in the Pro plan?

Pro ($9/month) gives you 15,000 recurring tokens. At 10 tokens per OpenAI: GPT-5 Nano use, that's ~1,500 full uses per cycle. If you run out, one-shot packs (5,000 / 25,000 / 80,000 tokens) add to the balance without expiring before one year.

What makes OpenAI: GPT-5 Nano special?

OpenAI is the lab behind ChatGPT; its models have broad world knowledge and polished outputs. Its specific strengths are: ultra-low latency, developer-optimized, and maximum energy efficiency. It accepts images as input (multimodal) as well as text — useful for describing captures, reading graphs, or solving problems from a photo.

How fast does OpenAI: GPT-5 Nano respond?

OpenAI: GPT-5 Nano has a balanced speed: 5-15 seconds per response — neither the fastest nor the slowest in the catalog. The actual time also depends on the length of the prompt and the load of the datacenter — models with huge context take longer when you enter very long texts.

How do I use OpenAI: GPT-5 Nano in ia.gratis?

You can use OpenAI: GPT-5 Nano from /chat/ by selecting OpenAI: GPT-5 Nano in the picker, or via the REST API with `model=gpt-5-nano` in the body of the POST. Quick summary: gPT-5 Nano: the fastest OpenAI model for developers and instant responses. The internal model identifier is `gpt-5-nano` — useful when integrating by API.
