GPT-5 nano 是 GPT-5 系列中面向速度与成本的轻量选择,适合摘要、分类和常规信息提取。你可以用它整理消息要点、给用户反馈打标签、生成简短标题,或将内容转换成固定字段。任务规则清楚、结果容易检查时,更适合投入高频调用。
它支持文字与图片输入,输出文字。除了处理文章和对话,也可以根据截图提取可见信息,例如整理错误提示、识别表单缺失项或概括商品说明。对于细小文字、金额与编号,要求保留原文并允许标记不确定内容,有助于后续校验。
结构化输出与函数调用便于它融入应用。分类结果可以交给工单系统,提取字段可以交给表单校验,用户意图也可以转成查询工具的参数。实际查询与写入由业务程序执行,模型负责理解输入并组织结果。
设计批量任务时,应明确每个标签的边界和缺失值规则,并提供少量正反例。输出越精简,越方便程序处理与监测。复杂的跨文件排错、模糊决策或需要深入论证的分析,可以先由它归纳材料,再转交给更适合的处理流程。
怎样选择适合的任务? 优先考虑有固定规则、短输出和明确验收方式的工作,如分类、摘要与字段提取。
长文都放进去会更好吗? 应先说明要提取什么,按主题组织内容;无关材料可能增加成本,也让重点更难控制。
列明输出字段与允许的取值,避免不必要的解释。
将这条产品反馈整理为 JSON:topic、sentiment、summary、needs_followup。
topic 只选性能、价格、易用性、功能或其他;summary 不超过 25 字。
needs_followup 仅在用户明确提出待处理问题时为 true。
不要补充原文没有的产品信息。
反馈:{用户原文}
摘要任务规定长度和必须覆盖的主题;图片提取要求看不清的字段写 null。用真实边界样本检查分类与格式,设置复杂任务的转交规则,再扩大调用量。

Replace <YOUR_API_KEY> with the API key from your token settings.
All requests must include Authorization: Bearer <TOKEN> header. Anthropic-formatted endpoints accept the x-api-key header instead.
Generate tokens from the Tokens page; you can scope them to specific models, groups, IPs, and rate-limits.

Compare gpt-5-nano API pricing, supported endpoints, capabilities and access options on Modelsell.
Create an API key with access to gpt-5-nano, then use the exact model ID and a supported endpoint from the API access section. Request fields depend on the selected endpoint.
Pricing depends on the selected provider group and the model billing unit. The current input, output, request, or media prices are shown on this page before sign-up.
The model catalog lists a context window of 400000 tokens. Check the selected endpoint for request limits.
The model catalog lists a maximum output of 128000 tokens. Your request settings may set a lower limit.
Start with the use cases and prompting guidance on this page, then evaluate the model with representative inputs from your project.
