GPT-5.5 适合需要同时理解大量材料、遵守多项约束并持续推进的任务。研发团队可以让它追踪跨文件故障、审查改动影响、制定迁移方案;产品和分析人员可以把需求、访谈、业务规则一起交给它,整理出有依据的决策建议。相比只问一个知识点,给它明确的完成目标与验收条件,更能发挥它在复杂专业工作中的作用。
它接受文本和图片,输出文字。你可以同时提供代码片段、错误日志和页面截图,让它把可见现象与实现逻辑联系起来;也可以让它检查流程图与方案说明是否一致。图片理解适合辅助分析,若要修改图片,需要另行接入相应的图像生成工具。
较大的上下文窗口便于放入长文档或较多代码,但材料仍应标明文件名、章节和优先级。要求它先建立证据索引,再执行分析,可以让结论更容易追溯。它还支持结构化输出与函数调用,适合把审核结果写成固定字段,或接入查询、计算、编辑等业务操作。
推理强度可按任务调整:简单整理可用较低强度,复杂排错、设计取舍可提高强度。联网检索、代码执行和文件操作需要在调用端配置工具与权限;如要自动处理任务,应明确哪些步骤可以执行、哪些结果需要人工复核。
适合整个仓库的修改吗? 可以参与跨文件分析与实现,建议提供目录、入口、相关测试和改动边界,并用实际测试验证结果。
怎样避免长材料中的结论混淆? 为每份材料编号,要求逐项列出结论对应的证据,未提供的事实单独标记为待确认。
提供目标、相关材料、允许的操作和完成标准。复杂工作可要求先列出依赖与待验证假设,随后逐步执行。
请审查这次订单幂等改造。材料包含接口代码、表结构、并发日志和现有测试。
目标:找出重复扣款仍可能发生的路径。
按触发条件、执行顺序、数据库状态和修复建议逐项说明;每项引用文件或日志位置。
最后给出最小修改方案和能复现问题的测试,不要改动结算规则。
如需程序消费结果,预先定义 JSON 字段与缺失值规则;如允许调用工具,写明可读写范围,并要求完成后报告执行结果和验证证据。

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-5.5 API pricing, supported endpoints, capabilities and access options on Modelsell.
Create an API key with access to gpt-5.5, 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.
