@galdor/provider-bedrock

The Amazon Bedrock provider adapter for galdor, speaking the Bedrock Runtime Converse API. Implements the core Provider interface, so it drops into any graph, agent, or council. Also ships a Bedrock embedder (Amazon Titan / Cohere) for the memory stack.

Bundles the full AWS credential chain, SigV4 request signing, and an event-stream decoder — no AWS SDK client required. Covers generate + streaming, tool calling, vision, reasoning/thinking (with signature and redacted-thinking round-trips), the typed error taxonomy with Retry-After, and cancellation.

Install

bun add @galdor/provider-bedrock   # or: npm install @galdor/provider-bedrock

Credentials

Resolved by the AWS default provider chain (environment variables → shared ~/.aws config → ECS container credentials → EC2 IMDS / task role). Only region is required; static keys are optional.

Usage

import { newBedrock } from "@galdor/provider-bedrock";
import { userMessage, messageText } from "@galdor/core/schema";

const provider = newBedrock({ region: "us-east-1" }); // default AWS chain

const res = await provider.generate({
  model: "anthropic.claude-3-haiku-20240307-v1:0",
  messages: [userMessage("Explain MCP in one sentence.")],
});
console.log(messageText(res.message), res.usage);

Embeddings

import { newEmbedder } from "@galdor/provider-bedrock"; // re-exported from the package entry

const embedder = newEmbedder({ region: "us-east-1", model: "amazon.titan-embed-text-v2:0", dim: 1024 });
const [vec] = await embedder.embed(["quito ecuador capital"]);

Titan and Cohere embedding families are supported; unknown model ids are rejected at construction, and throttling/5xx responses are retried with backoff.
