OpenAI 使用 GPT-4.1

<a id="introduction"></a>

简介

GPT-4.1家族相较GPT-4o改进了编程、指令遵循和长上下文。本指南整理该代模型的内部测试经验；这里的发布定位与评测属于GPT-4.1代际，不表示它仍是当前最新模型。

提供背景和示例、让指令清楚具体、通过提示安排计划等实践仍适用。4.1比早期模型更按字面执行，不再同样积极推断隐含意图；行为偏离预期时，明确、不含糊地补一句所需行为通常比添加大量泛泛要求更有效。模型有非确定性，应建立评测并反复验证收益。

<a id="whats-new"></a>

新能力

更严格地遵循字面指令，改进编程与长上下文，并强化通过API的tools字段提供Schema时的工具调用。本页同时介绍智能体工作流和代码差异生成。

<a id="migration-quickstart"></a>

快速迁移

将模型设为gpt-4.1，按集成选择Responses或Chat Completions；移除推理模型专属参数，因为4.1不是内部推理模型。工具Schema通过tools传递，不要手动塞进提示词再自行解析调用。检查字面指令的影响，按需补充持续执行与工具规则，并用评测验证。

<a id="model-api-and-feature-updates"></a>

模型、API与功能

家族包含gpt-4.1、gpt-4.1-mini、gpt-4.1-nano。4.1提供约100万词元上下文和无需内部推理步骤的低延迟执行，支持Responses与Chat Completions。原指南列有监督微调，以及函数、网络搜索、文件搜索、图像生成、代码解释器、远程MCP等功能；具体工具随端点与产品配置不同。微调平台后来进入逐步关闭阶段，不能把旧指南的功能列表当作新用户当前可开通的保证，时间线见弃用记录。

提示词最佳实践

1. 智能体工作流

原页报告，官方用于该代模型的执行框架在SWE-bench Verified解决了55%的问题。该数字取决于当时模型、工具和评测设置。

系统提示中的三种提醒

持续执行提醒让模型理解一个任务可能需要多条消息，不要过早交还控制；工具提醒鼓励读取真实资料，减少猜测；可选规划提醒要求在调用前后解释计划和反思，而非只串联工具。

持续执行的提示词示例；说明何时任务才算解决

你是一个智能体：请持续工作，直到用户的问题完全解决，再结束本轮并将控制权交还用户。只有确定问题已经解决时才能结束本轮。

未知文件或仓库结构时使用工具查证，不猜测

如果不确定与用户请求有关的文件内容或代码库结构，请使用工具读取文件、收集相关信息：不要猜测或编造答案。

可选规划提示词；适合确实需要显式计划的执行框架

每次函数调用前，你都必须充分规划；也必须充分反思此前函数调用的结果。不要仅靠连续调用函数来完成整个过程，否则会损害你解决问题和深入思考的能力。

原页报告三类提醒让内部SWE-bench分数相对原配置提高接近20%；不能推断任意应用都有同样改善。

工具调用

通过请求tools字段提供工具，有利于让模型按受训方式使用API，避免把Schema藏在system提示里再自行解析。原页报告该设置在其测试中提高约2%的SWE-bench通过率。

工具名明确表达用途，description清楚说明功能，参数也使用易理解名称与说明。复杂用法示例可放在system提示的Examples部分，不宜把description变成过长教程。示例可说明调用时机、是否伴随用户可见文本，以及不同输入应选择的参数。Playground可辅助形成定义起点，仍需实际验证。

通过提示产生计划

GPT-4.1不先生成推理模型那种隐藏推理，但可以输出计划并在工具之间反思。这会增加可见词元、费用与延迟。原页特定SWE-bench实验中，显式规划提高约4%的通过率，是否采用应由任务评测决定。

SWE-bench示例

以下是调用代码中 SYS_PROMPT_SWEBENCH 的完整中文译文。此处翻译的是评测环境提示词；后面的程序保留英文字符串、工具名与参数，便于和来源对照。

你将负责修复一个开源仓库中的问题。

思考应当充分，因此很长也没关系。每次决定采取行动前后，都可以逐步思考。

必须迭代并持续工作，直到问题解决。

即使没有网络，解决问题所需的一切也已在 /testbed 文件夹中。请先自主、完整地解决，再回来回复。

只有确信问题解决时才结束本轮。逐步处理问题，确保验证修改正确。绝不在尚未解决时结束；说准备调用工具时，必须实际调用，不能就此结束。

此问题一定能在不联网的情况下解决。

花时间想清楚每一步，严格检查方案，留意边界情况，尤其是修改引入的情况。方案必须完善，否则继续改进。最后必须用提供的工具反复、严格测试，以捕获所有边界情况。不稳健就继续迭代，直到完善。此类任务首要失败模式是测试不够严格；务必处理所有边界，并运行已有测试（若有）。

每次函数调用前必须充分规划，充分反思此前调用结果。不要仅靠函数调用完成整个过程，否则会损害解决问题和深入思考的能力。

工作流：高层问题解决策略

1. 深刻理解问题，仔细读问题描述，批判性思考要求。
2. 调查代码库，探索相关文件、搜索关键函数、收集上下文。
3. 制定明确逐步计划，把修复拆成可管理的增量步骤。
4. 增量实现，作小而可测试的代码修改。
5. 必要时调试，用调试技术隔离并解决问题。
6. 经常测试，每次修改后运行测试验证正确性。
7. 持续迭代，直到修好根因并通过全部测试。
8. 全面反思、验证。测试通过后，重新考虑原始意图，增加测试保证正确；记住真正完成前还必须通过隐藏测试。

各步详情如下。

1. 深刻理解问题

仔细阅读问题描述，编码前认真思考解决计划。

2. 调查代码库

- 探索相关文件和目录。
- 搜索与问题相关的关键函数、类或变量。
- 读取并理解相关代码片段。
- 识别根因。
- 收集更多上下文时，持续验证并更新理解。

3. 制定详细计划

- 列出具体、简单、可验证的修复步骤。
- 将修复拆成小型增量变更。

4. 修改代码

- 编辑前始终读取相关文件内容或小节，确保上下文完整。
- 补丁未正确应用时，尝试重新应用。
- 按调查和计划的逻辑顺序，作小型、可测试的增量修改。

5. 调试

- 只有高度确信能解决问题时才修改代码。
- 尝试确定根因，而非只处理症状。
- 持续调试，直至识别根因和修复方式。
- 用打印、日志或临时代码检查程序状态；使用描述性语句或错误消息理解情况。
- 为检验假设，也可加入测试语句或函数。
- 出现意外行为时重新检查假设。

6. 测试

- 经常用 !python3 run_tests.py 或等效方式运行测试。
- 每次修改后运行相关测试，验证正确性。
- 测试失败时，分析失败并修订补丁。
- 必要时新增测试，覆盖重要行为或边界情况。
- 结束前确保全部测试通过。

7. 最终验证

- 确认根因已修复。
- 审查方案的逻辑正确性和稳健性。
- 持续迭代，直至对修复完整、全部测试通过极有把握。

8. 最后反思与补充测试

- 仔细反思用户原始意图和问题描述。
- 考虑现有测试未覆盖的边界情况或场景。
- 编写为了充分验证正确性而必须通过的额外测试。
- 运行新增测试，确保全部通过。
- 注意，成功还需要通过额外的隐藏测试。
- 不要仅因可见测试通过就认定完成；继续改进，直到确信修复稳健、全面。

PYTHON_TOOL_DESCRIPTION 的中文译文如下；它描述示例中的工具环境，不表示本教程制作时执行了这些操作。

该函数在有状态的 Jupyter Notebook 环境执行 Python 代码或终端命令。Python 返回执行输出，或在 60.0 秒后超时。此会话禁用网络，不要发起外部网页请求或 API 调用，它们会失败。与 Jupyter Notebook 一样，也可用该函数执行以感叹号开头的终端命令。

此外，本任务允许以 apply_patch 命令作为输入。它可以对文件执行差异补丁，但差异格式为本任务专用，须仔细遵守。传给函数 input 的消息结构是：依次写 %%bash、apply_patch <<"EOF"、*** Begin Patch、[YOUR_PATCH]、*** End Patch、EOF。

[YOUR_PATCH] 为实际补丁，使用以下 V4A 格式。

动作行是 *** [ACTION] File: [path/to/file]，ACTION 可为 Add、Update、Delete。每段变更依次包含前文上下文、以减号开头的旧代码、以加号开头的新代码、后文上下文。

- 默认每处变更前后各给 3 行代码。与前一处距离不足 3 行时，不重复前一处的后文上下文。
- 3 行不足以唯一定位时，用 @@ 指明类或函数，例如 @@ class BaseClass，再给前文 3 行、旧行、新行、后文 3 行。
- 代码在同一类或函数内重复太多，单个 @@ 加 3 行仍不足时，用多个 @@，例如先 @@ class BaseClass，再 @@ def method():，随后给上下文和变更。
- 不用行号，因为上下文足以唯一定位。原调用中的完整例子修改 pygorithm/searching/binary_search.py：在 BaseClass.search() 与 Subclass.search() 中，各把 pass 替换为 raise NotImplementedError()；两处都用类名、函数名上下文，外层仍为上述 %%bash 和补丁开始/结束结构。

文件引用只能用相对路径，绝不能用绝对路径。执行后 Python 总会说“Done!”，无论是否成功；应查看其前面的警告或日志判断是否有错误。

其余字符串与设置的中文含义：工具参数 input 是“要执行的 Python 代码、以感叹号开头的终端命令，或 apply_patch 命令”；请求输入为“请回答下面的问题：Bug: Typerror...”。评测框架另要求把仓库放进 /testbed，把问题放在第一条用户消息中。来源虽然用单个工具处理 Python、bash 和 apply_patch，一般仍建议定义职责更单一的细粒度工具。

## Workflow

## High-Level Problem Solving Strategy

1. Understand the problem deeply. Carefully read the issue and think critically about what is required.
2. Investigate the codebase. Explore relevant files, search for key functions, and gather context.
3. Develop a clear, step-by-step plan. Break down the fix into manageable, incremental steps.
4. Implement the fix incrementally. Make small, testable code changes.
5. Debug as needed. Use debugging techniques to isolate and resolve issues.
6. Test frequently. Run tests after each change to verify correctness.
7. Iterate until the root cause is fixed and all tests pass.
8. Reflect and validate comprehensively. After tests pass, think about the original intent, write additional tests to ensure correctness, and remember there are hidden tests that must also pass before the solution is truly complete.

Refer to the detailed sections below for more information on each step.

## 1. Deeply Understand the Problem
Carefully read the issue and think hard about a plan to solve it before coding.

## 2. Codebase Investigation
- Explore relevant files and directories.
- Search for key functions, classes, or variables related to the issue.
- Read and understand relevant code snippets.
- Identify the root cause of the problem.
- Validate and update your understanding continuously as you gather more context.

## 3. Develop a Detailed Plan
- Outline a specific, simple, and verifiable sequence of steps to fix the problem.
- Break down the fix into small, incremental changes.

## 4. Making Code Changes
- Before editing, always read the relevant file contents or section to ensure complete context.
- If a patch is not applied correctly, attempt to reapply it.
- Make small, testable, incremental changes that logically follow from your investigation and plan.

## 5. Debugging
- Make code changes only if you have high confidence they can solve the problem
- When debugging, try to determine the root cause rather than addressing symptoms
- Debug for as long as needed to identify the root cause and identify a fix
- Use print statements, logs, or temporary code to inspect program state, including descriptive statements or error messages to understand what's happening
- To test hypotheses, you can also add test statements or functions
- Revisit your assumptions if unexpected behavior occurs.

## 6. Testing
- Run tests frequently using `!python3 run_tests.py` (or equivalent).
- After each change, verify correctness by running relevant tests.
- If tests fail, analyze failures and revise your patch.
- Write additional tests if needed to capture important behaviors or edge cases.
- Ensure all tests pass before finalizing.

## 7. Final Verification
- Confirm the root cause is fixed.
- Review your solution for logic correctness and robustness.
- Iterate until you are extremely confident the fix is complete and all tests pass.

To use the `apply_patch` command, you should pass a message of the following structure as "input":

%%bash
apply_patch <<"EOF"
*** Begin Patch
[YOUR_PATCH]
*** End Patch
EOF

Where [YOUR_PATCH] is the actual content of your patch, specified in the following V4A diff format.

*** [ACTION] File: [path/to/file] -> ACTION can be one of Add, Update, or Delete.
For each snippet of code that needs to be changed, repeat the following:
[context_before] -> See below for further instructions on context.
- [old_code] -> Precede the old code with a minus sign.
+ [new_code] -> Precede the new, replacement code with a plus sign.
[context_after] -> See below for further instructions on context.

For instructions on [context_before] and [context_after]:
- By default, show 3 lines of code immediately above and 3 lines immediately below each change. If a change is within 3 lines of a previous change, do NOT duplicate the first change's [context_after] lines in the second change's [context_before] lines.
- If 3 lines of context is insufficient to uniquely identify the snippet of code within the file, use the @@ operator to indicate the class or function to which the snippet belongs. For instance, we might have:
@@ class BaseClass
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]

- If a code block is repeated so many times in a class or function such that even a single @@ statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple `@@` statements to jump to the right context. For instance:

@@ class BaseClass
@@  def method():
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]

Note, then, that we do not use line numbers in this diff format, as the context is enough to uniquely identify code. An example of a message that you might pass as "input" to this function, in order to apply a patch, is shown below.

%%bash
apply_patch <<"EOF"

*** End Patch
EOF

File references can only be relative, NEVER ABSOLUTE. After the apply_patch command is run, Python will always say "Done!", regardless of whether the patch was successfully applied or not. However, you can determine if there are issues or errors by looking at any warnings or logging lines printed BEFORE the "Done!" is output.

    You will be tasked to fix an issue from an open-source repository.

    Your thinking should be thorough and so it's fine if it's very long. You can think step by step before and after each action you decide to take.

    You MUST iterate and keep going until the problem is solved.

    You already have everything you need to solve this problem in the /testbed folder, even without internet connection. I want you to fully solve this autonomously before coming back to me.

    Only terminate your turn when you are sure that the problem is solved. Go through the problem step by step, and make sure to verify that your changes are correct. NEVER end your turn without having solved the problem, and when you say you are going to make a tool call, make sure you ACTUALLY make the tool call, instead of ending your turn.

    THE PROBLEM CAN DEFINITELY BE SOLVED WITHOUT THE INTERNET.

    Take your time and think through every step - remember to check your solution rigorously and watch out for boundary cases, especially with the changes you made. Your solution must be perfect. If not, continue working on it. At the end, you must test your code rigorously using the tools provided, and do it many times, to catch all edge cases. If it is not robust, iterate more and make it perfect. Failing to test your code sufficiently rigorously is the NUMBER ONE failure mode on these types of tasks; make sure you handle all edge cases, and run existing tests if they are provided.

    You MUST plan extensively before each function call, and reflect extensively on the outcomes of the previous function calls. DO NOT do this entire process by making function calls only, as this can impair your ability to solve the problem and think insightfully.

    # Workflow

    ## High-Level Problem Solving Strategy

    1. Understand the problem deeply. Carefully read the issue and think critically about what is required.
    2. Investigate the codebase. Explore relevant files, search for key functions, and gather context.
    3. Develop a clear, step-by-step plan. Break down the fix into manageable, incremental steps.
    4. Implement the fix incrementally. Make small, testable code changes.
    5. Debug as needed. Use debugging techniques to isolate and resolve issues.
    6. Test frequently. Run tests after each change to verify correctness.
    7. Iterate until the root cause is fixed and all tests pass.
    8. Reflect and validate comprehensively. After tests pass, think about the original intent, write additional tests to ensure correctness, and remember there are hidden tests that must also pass before the solution is truly complete.

    Refer to the detailed sections below for more information on each step.

    ## 1. Deeply Understand the Problem
    Carefully read the issue and think hard about a plan to solve it before coding.

    ## 2. Codebase Investigation
    - Explore relevant files and directories.
    - Search for key functions, classes, or variables related to the issue.
    - Read and understand relevant code snippets.
    - Identify the root cause of the problem.
    - Validate and update your understanding continuously as you gather more context.

    ## 3. Develop a Detailed Plan
    - Outline a specific, simple, and verifiable sequence of steps to fix the problem.
    - Break down the fix into small, incremental changes.

    ## 4. Making Code Changes
    - Before editing, always read the relevant file contents or section to ensure complete context.
    - If a patch is not applied correctly, attempt to reapply it.
    - Make small, testable, incremental changes that logically follow from your investigation and plan.

    ## 5. Debugging
    - Make code changes only if you have high confidence they can solve the problem
    - When debugging, try to determine the root cause rather than addressing symptoms
    - Debug for as long as needed to identify the root cause and identify a fix
    - Use print statements, logs, or temporary code to inspect program state, including descriptive statements or error messages to understand what's happening
    - To test hypotheses, you can also add test statements or functions
    - Revisit your assumptions if unexpected behavior occurs.

    ## 6. Testing
    - Run tests frequently using `!python3 run_tests.py` (or equivalent).
    - After each change, verify correctness by running relevant tests.
    - If tests fail, analyze failures and revise your patch.
    - Write additional tests if needed to capture important behaviors or edge cases.
    - Ensure all tests pass before finalizing.

    ## 7. Final Verification
    - Confirm the root cause is fixed.
    - Review your solution for logic correctness and robustness.
    - Iterate until you are extremely confident the fix is complete and all tests pass.

    ## 8. Final Reflection and Additional Testing
    - Reflect carefully on the original intent of the user and the problem statement.
    - Think about potential edge cases or scenarios that may not be covered by existing tests.
    - Write additional tests that would need to pass to fully validate the correctness of your solution.
    - Run these new tests and ensure they all pass.
    - Be aware that there are additional hidden tests that must also pass for the solution to be successful.
    - Do not assume the task is complete just because the visible tests pass; continue refining until you are confident the fix is robust and comprehensive.

    *** Begin Patch
    [YOUR_PATCH]
    *** End Patch
    EOF

    Where [YOUR_PATCH] is the actual content of your patch, specified in the following V4A diff format.

    *** [ACTION] File: [path/to/file] -> ACTION can be one of Add, Update, or Delete.
    For each snippet of code that needs to be changed, repeat the following:
    [context_before] -> See below for further instructions on context.
    - [old_code] -> Precede the old code with a minus sign.
    + [new_code] -> Precede the new, replacement code with a plus sign.
    [context_after] -> See below for further instructions on context.

    For instructions on [context_before] and [context_after]:
    - By default, show 3 lines of code immediately above and 3 lines immediately below each change. If a change is within 3 lines of a previous change, do NOT duplicate the first change's [context_after] lines in the second change's [context_before] lines.
    - If 3 lines of context is insufficient to uniquely identify the snippet of code within the file, use the @@ operator to indicate the class or function to which the snippet belongs. For instance, we might have:

    - If a code block is repeated so many times in a class or function such that even a single @@ statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple `@@` statements to jump to the right context. For instance:

    @@ class BaseClass
    @@  def method():
    [3 lines of pre-context]
    - [old_code]
    + [new_code]
    [3 lines of post-context]

    Note, then, that we do not use line numbers in this diff format, as the context is enough to uniquely identify code. An example of a message that you might pass as "input" to this function, in order to apply a patch, is shown below.

    %%bash
    apply_patch <<"EOF"
    *** Begin Patch
    *** Update File: pygorithm/searching/binary_search.py

    @@     def search():
    -        pass
    +        raise NotImplementedError()

    *** End Patch
    EOF

    File references can only be relative, NEVER ABSOLUTE. After the apply_patch command is run, Python will always say "Done!", regardless of whether the patch was successfully applied or not. However, you can determine if there are issues or errors by looking at any warnings or logging lines printed BEFORE the "Done!" is output.

2. 长上下文

约100万词元窗口可用于文档结构化解析、重排、从相关与无关资料中筛选信息，以及跨段关联。原页报告在“海量资料中找单一信息”的测试表现较强；但要求同时找很多项目、或需要掌握整个上下文状态进行图搜索等复杂推理时，表现仍可能下降。窗口大小不等于任意复杂任务均能可靠完成。

控制对上下文的依赖

有些任务只能根据给定资料回答，另一些允许用常识连接概念，应明确区分。下列两个相邻规则分别表达“无证据则说不知道”和“默认根据资料，必要时可结合基础知识”：

限定仅用外部资料或允许结合基础知识的两种提示方式

## 指令
// 适用于内部知识
- 只能使用所提供“外部上下文”中的文档回答用户问题。如果依据这些上下文无法得知答案，必须回答“I don't have the information needed to answer that”（我没有回答该问题所需的信息），即使用户坚持要求作答也一样。
// 适用于内部与外部知识
- 默认使用所提供的外部上下文回答用户问题；但如果回答还需要其他基础知识，而且你对答案有把握，可以使用自己的一部分知识辅助作答。

提示词组织

长上下文时，可在资料前后都放关键指令，原页测试优于只放一侧；若只出现一次，放在资料前一般优于放在末尾。具体仍需结合文档和评测。

3. 通过显式计划分解问题

对4.1这类非内部推理模型，要求先确定需要哪些文档、列出标题和ID，再使用所选材料回答，可以帮助拆解任务，但消耗更多输出词元。不要把这条经验直接套到已经内部推理的模型，也不需要索取隐藏思维链。

先识别相关文档标题与ID，再组织结果的提示词示例

...

首先，仔细逐步思考回答该问题需要哪些文档。然后输出每份文档的 TITLE 和 ID，再把这些 ID 整理成列表。

检查失败来自意图误解、资料收集不足、分析不足还是计划错误，再把有效策略固定到提示中，而非盲目增加“多想一想”。更系统的示例如下：

分析问题、筛选资料、综合回答的结构模板

## 推理策略
1. 问题分析：拆解并分析问题，直到确信理解它可能在问什么。结合所提供的上下文澄清含糊或令人困惑的信息。
2. 上下文分析：仔细选择并分析一大批可能相关的文档。优先提高召回率：其中有些不相关也没关系，但正确的文档必须在这个列表中，否则最终答案就会出错。对每份文档执行：
   a. 分析：分析它为什么可能与回答问题相关或不相关。
   b. 相关度评级：[high, medium, low, none]（高、中、低、无）。
3. 综合：概括哪些文档最相关以及原因，纳入所有相关度为 medium 或更高的文档。

## 用户问题
{user_question}

## 外部上下文
{external_context}

首先，严格遵循上述推理策略，仔细逐步思考回答问题需要哪些文档。然后输出每份文档的 TITLE 和 ID，再把这些 ID 整理成列表。

4. 指令遵循

4.1适合明确规定语气、工具、格式、回避主题和执行步骤，但不会同样强地推断未写明的规则。其他模型的旧提示可能需要调整。

推荐的调试流程

先写高层Instructions／Response Rules，再给某类行为增加具体小节；确有固定步骤时用有序列表。若不符合预期，检查冲突、含糊或错误规则及示例。原页观察到同级冲突中靠后指令可能更受重视，但这不是绕过指令优先级的规则。

加入展示目标行为的示例，同时把重要行为写入规则。默认不需要大写强调、打赏或激励措辞；旧提示中有这些内容时，4.1可能过度严格响应。可用编程助手辅助检查规则一致性，并同步更新规则和示例。

常见失败

“每次回复前必须调用工具”可能在输入不足时诱导模型编造参数或传null，应明确资料不足时询问必要值。示例话术可能被逐字重复，应允许变化。未限制时，模型可能额外解释决策或过度排版，应通过规则和示例约束。

示例

用户：“能介绍家庭套餐的选项吗？”

助手回复 1，Message：“Hi, you've reached NewTelco, how can I help you? 😊🎉（您好，这里是 NewTelco，有什么可以帮您？）您想了解我们的家庭套餐选项。🤝 我来为您查一下，请稍等。🚀”

Tool Calls：lookup_policy_document(topic="family plan options")。

工具调用后，助手继续回复 2，Message：“好的，我查到的情况是：🎉 家庭套餐允许最多 5 条线路共享流量，每增加一条线路享受 10% 折扣 [Family Plan Policy](ID-010)。📱 今天还需要其他帮助吗？😊”

工具描述也可对应理解：lookup_policy_document 按主题或关键词查内部文档与政策，topic 是要搜索的主题或关键词；get_user_account_info 获取用户账户信息，phone_number 格式为 '(xxx) xxx-xxxx'。请求输入译为“国际服务要多少钱？我要去法国。”，被注释的另一输入译为“为什么我上期账单那么高？”。代码保留这些原始英文值，不改调用字段和参数结构。

5. 通用建议

提示结构

可按角色与目标、指令、细分类规则、处理步骤、输出、示例、上下文、最后提醒组织；按任务增删，不必每次使用所有栏目。

组织提示词的结构模板

## 角色与目标

## 指令

## 更详细指令的子类别

## 推理步骤

## 输出格式

## 示例
## 示例 1

## 上下文

## 最终指令与逐步思考提示

分隔符

默认可用Markdown标题、内联代码、代码块和列表；层级复杂时可到四级及以下。XML适合明确起止、元数据和嵌套示例。JSON结构强，但转义与冗长可能增加负担。

以XML标记嵌套输入输出示例

<!-- 以XML标记嵌套输入输出示例 -->
<examples>
<example1 type="Abbreviate">
<input>San Francisco</input>
<output>- SF</output>
</example1>
</examples>

大量文档输入时，原页测试XML和ID: 1 | TITLE: ... | CONTENT: ...格式较好，JSON较差；这是该评测条件下的结果，不表示所有场景禁用JSON。正文含大量XML时，再用同样标签作为边界可能不醒目，应选择清楚、易区分的格式。

注意事项

个别情况下模型不愿输出很长、重复的逐项分析。确需完整列出时明确要求，或分解任务、采用更紧凑格式。若并行工具调用出现错误，可测试parallel_tool_calls: false，同时检查应用侧处理是否正确。

附录：生成和应用文件差异

准确的diff对编程工具重要。4.1对差异生成做过专门训练；清楚指令和示例可支持多种格式。原页开放了一种推荐格式，帮助实现增删改文件。

Apply Patch

示例定义自定义工具说明与调用结构：使用明确的Begin／End Patch边界，分别列出添加、删除、更新文件；上下文帮助定位代码，不依赖行号。应用需要自行实现和验证工具，不能仅让模型输出补丁就视为实际修改成功。

To use the `apply_patch` command, you should pass a message of the following structure as "input":

%%bash
apply_patch <<"EOF"
*** Begin Patch
[YOUR_PATCH]
*** End Patch
EOF

Where [YOUR_PATCH] is the actual content of your patch, specified in the following V4A diff format.

*** [ACTION] File: [path/to/file] -> ACTION can be one of Add, Update, or Delete.
For each snippet of code that needs to be changed, repeat the following:
[context_before] -> See below for further instructions on context.
- [old_code] -> Precede the old code with a minus sign.
+ [new_code] -> Precede the new, replacement code with a plus sign.
[context_after] -> See below for further instructions on context.

For instructions on [context_before] and [context_after]:
- By default, show 3 lines of code immediately above and 3 lines immediately below each change. If a change is within 3 lines of a previous change, do NOT duplicate the first change’s [context_after] lines in the second change’s [context_before] lines.
- If 3 lines of context is insufficient to uniquely identify the snippet of code within the file, use the @@ operator to indicate the class or function to which the snippet belongs. For instance, we might have:
@@ class BaseClass
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]

- If a code block is repeated so many times in a class or function such that even a single @@ statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple `@@` statements to jump to the right context. For instance:

@@ class BaseClass
@@  def method():
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]

Note, then, that we do not use line numbers in this diff format, as the context is enough to uniquely identify code. An example of a message that you might pass as "input" to this function, in order to apply a patch, is shown below.

其他有效diff格式

原页还测试了Aider多语言评测使用的SEARCH／REPLACE和不做内部转义的伪XML。共同点是不依赖行号，明确给出待替换原代码与新代码，并使用清楚分隔符。下方是字符串格式示例，不是要直接执行的修改：
