GPT-5.4 Pro 面向需要反复推敲的工作,例如梳理跨服务故障、比较架构方案、检查算法边界,或从多份技术材料中找出相互矛盾的条件。它使用更多计算进行推理,接受文本和图片,输出文字分析与代码,适合对结论细节有较高要求的任务。
百万级上下文可以容纳较长的设计文档、日志片段、代码和讨论记录。材料较多时,先说明时间顺序、版本与各自用途,再要求模型把证据组成完整链条。图片可用于补充架构图、界面状态或图表,让文字描述与可见现象一起参与分析。
排障时可以要求按“触发条件、传播路径、可观察证据、修复与验证”展开,避免只得到常见原因清单。方案比较则应明确约束,例如延迟、可用性、改造范围和恢复成本,并要求检查失败情景与反例。资料不足的部分应列成待验证问题,后续补充结果再继续推理。
模型在 Responses 中支持函数调用、搜索、文件检索和计算机操作等工具协作。应用需要配置工具权限与执行环境,并传回实际结果,让后续分析基于新的观察。
本模型使用 Responses API,reasoning.effort 可选 medium、high 和 xhigh,默认 medium。困难请求可能需要数分钟,应安排足够的超时和任务状态管理;应用支持时可采用后台执行。适合需要深入分析的工作,使用前可先明确本轮最重要的判断与交付结果。
“结合调用链、错误日志、配置变更记录和架构图,重建这次超时发生的过程。检查哪些证据支持连接池耗尽,哪些现象还不能解释;比较临时缓解与长期修复方案,给出最小验证步骤及失败时的恢复条件。”
先标明时间范围与服务关系,保留关键上下游记录,说明哪些字段可关联同一请求,减少无关重复材料。
从 medium 开始,复杂且需要更深入分析的任务再考虑 high 或 xhigh,同时预留更长等待时间并检查实际结果。

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-5.4-pro API pricing, supported endpoints, capabilities and access options on Modelsell.
Create an API key with access to gpt-5.4-pro, 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 1050000 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.
