> Last verified: 2026-05-18. 本表用于维护提示词工程中模型、API、上下文、成本、MCP 与 benchmark 的高波动事实。

| 类别        | 当前维护口径                                                       | 权威入口                                                                                                                                        | 编辑要求                              |
| --------- | ------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------- |
| OpenAI    | GPT-5.x、Responses API、Agents SDK、built-in tools 以官方 docs 为准。 | [OpenAI Models](https://developers.openai.com/api/docs/models/all/), [Responses API](https://developers.openai.com/api/reference/responses) | 新示例优先使用当前推荐 API；历史 API 标注 legacy。 |
| Anthropic | Claude 4.x、thinking、tool use、Claude Code 以官方文档为准。            | [Claude Models](https://platform.claude.com/docs/en/about-claude/models/overview), [Claude Code Docs](https://code.claude.com/docs/)        | 不预测未发布模型，不把 beta 当 GA。            |
| Gemini    | Gemini 3.x、实时多模态、Deep Think 以 Google AI docs 为准。             | [Gemini Models](https://ai.google.dev/gemini-api/docs/models)                                                                               | 同一书内只使用官方命名。                      |
| MCP       | MCP prompt/resource/tool/server 语义以规范为准。                     | [MCP Spec](https://modelcontextprotocol.io/specification)                                                                                   | token 节省等数字必须有来源或标为示意。            |
| 评估与成本     | PromptOps、A/B eval、token 成本、benchmark 只作为 dated snapshot。    | 官方 pricing、eval 工具文档、论文                                                                                                                     | 不能把示例数据写成通用收益。                    |

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://yeasy.gitbook.io/prompt_engineering_guide/fu-lu/h_volatile_facts.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
