Bedrock

Usage

import { BEDROCK_MODELS, Bedrock } from "@llamaindex/community";

Settings.llm = new Bedrock({
  model: BEDROCK_MODELS.ANTHROPIC_CLAUDE_3_HAIKU,
  region: "us-east-1", // can be provided via env AWS_REGION
  credentials: {
    accessKeyId: "...", // optional and can be provided via env AWS_ACCESS_KEY_ID
    secretAccessKey: "...", // optional and can be provided via env AWS_SECRET_ACCESS_KEY
  },
});

Currently only supports Anthropic and Meta models:

ANTHROPIC_CLAUDE_INSTANT_1 = "anthropic.claude-instant-v1";
ANTHROPIC_CLAUDE_2 = "anthropic.claude-v2";
ANTHROPIC_CLAUDE_2_1 = "anthropic.claude-v2:1";
ANTHROPIC_CLAUDE_3_SONNET = "anthropic.claude-3-sonnet-20240229-v1:0";
ANTHROPIC_CLAUDE_3_HAIKU = "anthropic.claude-3-haiku-20240307-v1:0";
ANTHROPIC_CLAUDE_3_OPUS = "anthropic.claude-3-opus-20240229-v1:0"; // available on us-west-2
ANTHROPIC_CLAUDE_3_5_SONNET = "anthropic.claude-3-5-sonnet-20240620-v1:0";
META_LLAMA2_13B_CHAT = "meta.llama2-13b-chat-v1";
META_LLAMA2_70B_CHAT = "meta.llama2-70b-chat-v1";
META_LLAMA3_8B_INSTRUCT = "meta.llama3-8b-instruct-v1:0";
META_LLAMA3_70B_INSTRUCT = "meta.llama3-70b-instruct-v1:0";
META_LLAMA3_1_8B_INSTRUCT = "meta.llama3-1-8b-instruct-v1:0"; // available on us-west-2
META_LLAMA3_1_70B_INSTRUCT = "meta.llama3-1-70b-instruct-v1:0"; // available on us-west-2
META_LLAMA3_1_405B_INSTRUCT = "meta.llama3-1-405b-instruct-v1:0"; // preview only, available on us-west-2, tool calling supported

Sonnet, Haiku and Opus are multimodal, image_url only supports base64 data url format, e.g. data:image/jpeg;base64,SGVsbG8sIFdvcmxkIQ==

Full Example

import { BEDROCK_MODELS, Bedrock } from "llamaindex";

Settings.llm = new Bedrock({
  model: BEDROCK_MODELS.ANTHROPIC_CLAUDE_3_HAIKU,
});

async function main() {
  const document = new Document({ text: essay, id_: "essay" });

  // Load and index documents
  const index = await VectorStoreIndex.fromDocuments([document]);

  // Create a query engine
  const queryEngine = index.asQueryEngine({
    retriever,
  });

  const query = "What is the meaning of life?";

  // Query
  const response = await queryEngine.query({
    query,
  });

  // Log the response
  console.log(response.response);
}
