GPT-5.1 可以根据任务需要选择是否进行额外推理。客服解释、文案调整和简单信息提取可以采用非推理设置;代码排错、条件判断和多步骤规划则可以增加推理强度。对于任务难度变化较大的助手应用,这种调节方式便于控制响应时间与分析深度。
它接受文本和图片,能够理解代码、业务文档、页面截图与图表,再输出文字、代码或结构化结果。比如,把接口报错与调用代码一起提供,要求找出参数处理的问题;把页面截图与设计要求对照,要求列出布局、文案和状态提示的差异。
它适合参与智能体流程,通过函数调用连接查询、文件处理和业务操作。使用 Responses API 并配置相应工具时,还可以结合检索、文件搜索和代码执行完成更具体的工作。调用端应提供清楚的工具说明,并让模型在拿到返回结果后再继续判断。
较大的上下文有助于保留项目资料与历史讨论。持续协作时,最好维护一份简短的任务状态:已经确认的事实、当前修改范围和尚待验证的问题。这样比反复发送无关历史更容易保持工作方向。需要稳定结果格式时,预先定义输出字段与缺失值处理方式。
推理强度可以怎样选? 支持 none、low、medium 和 high。先用代表任务比较响应与质量,再为不同类型请求选择合适设置。
能自动查到新资料吗? 接入并启用搜索或其他查询工具后才能获取外部信息;对于指定材料分析,可以要求只使用输入内容。
简单工作写清格式,复杂工作补充证据与验收标准。
请检查这个 CSV 导入接口为何会把合法的 0 值当成缺失。
材料包括 DTO、校验逻辑、数据库写入和失败样本。
沿字段流转顺序定位丢失位置,解释原因,给出最小修复与回归用例。
保留空值和显式 0 的区别,不改其他字段规则。
此类多环节排错可使用较高推理强度;只提取列名或改写提示语时可用 none。工具任务明确哪些操作允许执行,结束时要求报告真实结果和验证情况。

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-5.1 API pricing, supported endpoints, capabilities and access options on Modelsell.
Create an API key with access to gpt-5.1, 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.
