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 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

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