Arcjet Redact
Arcjet redact 集成允许您在将敏感用户信息发送到 LLM 之前从提示中编辑掉这些信息。
Arcjet Redact 完全在您自己的机器上运行,绝不会将数据发送到任何其他地方,从而确保一流的隐私和性能。
Arcjet Redact 对象本身不是 LLM,而是包装了一个 LLM。它编辑输入到其中的文本,然后在返回之前取消编辑包装的 LLM 的输出。

用法
import {
ArcjetRedact,
ArcjetSensitiveInfoType,
} from "@langchain/community/llms/arcjet";
import { OpenAI } from "@langchain/openai";
// Create an instance of another LLM for Arcjet to wrap
const openai = new OpenAI({
modelName: "gpt-3.5-turbo-instruct",
openAIApiKey: process.env.OPENAI_API_KEY,
});
const arcjetRedactOptions = {
// Specify a LLM that Arcjet Redact will call once it has redacted the input.
llm: openai,
// Specify the list of entities that should be redacted.
// If this isn't specified then all entities will be redacted.
entities: [
"email",
"phone-number",
"ip-address",
"credit-card",
] as ArcjetSensitiveInfoType[],
// You can provide a custom detect function to detect entities that we don't support yet.
// It takes a list of tokens and you return a list of identified types or undefined.
// The undefined types that you return should be added to the entities list if used.
detect: (tokens: string[]) => {
return tokens.map((t) =>
t === "some-sensitive-info" ? "custom-entity" : undefined
);
},
// The number of tokens to provide to the custom detect function. This defaults to 1.
// It can be used to provide additional context when detecting custom entity types.
contextWindowSize: 1,
// This allows you to provide custom replacements when redacting. Please ensure
// that the replacements are unique so that unredaction works as expected.
replace: (identifiedType: string) => {
return identifiedType === "email" ? "redacted@example.com" : undefined;
},
};
const arcjetRedact = new ArcjetRedact(arcjetRedactOptions);
const response = await arcjetRedact.invoke(
"My email address is test@example.com, here is some-sensitive-info"
);
