const message = await client.messages.create({ model: "claude-opus-5-5", max_tokens: 1024, system: "Always respond in French, regardless of the language the user writes in.", messages: [{ role: "user", content: "How do I reset my password?" }] }); console.log(message.content); ``` ```csharp C# AnthropicClient client = new(); var parameters = new MessageCreateParams { Model = Model.ClaudeOpus5_5, MaxTokens = 1024, System = "Always respond in French, regardless of the language the user writes in.", Messages = [new UserMessageParam { Content = "How do I reset my password?" }] }; var message = await client.Messages.Create(parameters); Console.WriteLine(message); ``` ```go Go client := anthropic.NewClient() message, err := client.Messages.New(context.TODO(), anthropic.MessageNewParams{ Model: anthropic.ModelClaudeOpus5_5, MaxTokens: 1024, System: []anthropic.TextBlockParam{ {Text: "Always respond in French, regardless of the language the user writes in."}, }, Messages: []anthropic.MessageParam{ anthropic.NewUserMessage(anthropic.NewTextBlock("How do I reset my password?")), }, }) if err != nil { log.Fatal(err) } fmt.Println(message.Content) ``` ```java Java AnthropicClient client = AnthropicOkHttpClient.fromEnv(); MessageCreateParams params = MessageCreateParams.builder() .model(Model.CLAUDE_OPUS_5_5) .maxTokens(1024) .system("Always respond in French, regardless of the language the user writes in.") .addUserMessage("How do I reset my password?") .build(); Message message = client.messages().create(params); System.out.println(message.content()); ``` ```php PHP $client = new Client(); $message = $client->messages->create( maxTokens: 1024, messages: [ ['role' => 'user', 'content' => 'How do I reset my password?'] ], model: Model::CLAUDE_OPUS_5_5, system: 'Always respond in French, regardless of the language the user writes in.', ); echo json_encode($message->content, JSON_PRETTY_PRINT), PHP_EOL; ``` ```ruby Ruby client = Anthropic::Client.new message = client.messages.create( model: Anthropic::Model::CLAUDE_OPUS_5_5, max_tokens: 1024, system: "Always respond in French, regardless of the language the user writes in.", messages: [ { role: "user", content: "How do I reset my password?" } ] ) puts message.content ``` 如果您的应用允许用户在运行时选择语言，请将该选择插入到系统提示中，而不是依赖 Claude 从用户消息中推断。若要在两种特定语言之间进行翻译，请同时指明两种语言：`Translate the user's message from German to Korean. Respond with only the translation.` *** ## 最佳实践 处理多语言内容时： 1. **提供清晰的语言上下文：** 虽然 Claude 可以自动检测目标语言，但明确说明您想要的输入和输出语言可以提高可靠性。为了增强流畅度，您可以提示 Claude 使用"如同母语者般的地道表达"。 2. **使用原生文字：** 提交文本时请使用其原生文字而非音译，以获得最佳效果。 3. **考虑文化背景：** 有效的沟通通常需要超越纯粹翻译的文化和地区意识。 另请遵循[提示工程概述](https://platform.claude.com/docs/zh-CN/build-with-claude/prompt-engineering/overview)中的通用指导，以进一步提升输出质量。 *** ## 语言支持注意事项 * Claude 可以处理大多数使用标准 Unicode 字符的世界语言的输入并生成输出。 * 性能因语言而异，在广泛使用的语言中能力尤为突出。 * 即使在数字资源较少的语言中，Claude 仍保持有意义的能力。 ## 后续步骤 应用通用提示技巧以提升多语言输出质量。 构建一个客户支持聊天机器人。一个聊天机器人即可为使用多种语言的客户提供服务。 比较各模型层级，在多语言质量与成本和延迟之间取得平衡。 应用通用的评估方法来衡量您所支持的每种语言的输出质量。 ## 可用性 多语言支持在所有模型上可用。 ### API 支持 #### [Messages API](https://platform.claude.com/docs/zh-CN/build-with-claude/working-with-messages) * 可用性：始终开启 | 状态 | 云平台 | | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | 可用 | Claude API, [Claude Platform on AWS](https://platform.claude.com/docs/zh-CN/build-with-claude/claude-platform-on-aws), [Amazon Bedrock](https://platform.claude.com/docs/zh-CN/build-with-claude/claude-in-amazon-bedrock), [Amazon Bedrock (InvokeModel)](https://platform.claude.com/docs/zh-CN/build-with-claude/claude-on-amazon-bedrock-legacy), [Claude Models on Google Cloud (Google managed)](https://platform.claude.com/docs/zh-CN/build-with-claude/claude-models-on-google-cloud/google-managed), [Microsoft Foundry](https://platform.claude.com/docs/zh-CN/build-with-claude/claude-in-microsoft-foundry) | #### [Managed Agents](https://platform.claude.com/docs/zh-CN/managed-agents/overview) * 可用性：始终开启 | 状态 | 云平台 | | -- | --------------------------------------------------------------------------------------------------------------------- | | 可用 | Claude API, [Claude Platform on AWS](https://platform.claude.com/docs/zh-CN/build-with-claude/claude-platform-on-aws) |
