+summary: "Use Amazon Bedrock (Converse API) models with Clawdbot"
+read_when:
+  - You want to use Amazon Bedrock models with Clawdbot
+  - You need AWS credential/region setup for model calls
+---
+# Amazon Bedrock
+
+Clawdbot can use **Amazon Bedrock** models via pi‑ai’s **Bedrock Converse**
+streaming provider. Bedrock auth uses the **AWS SDK default credential chain**,
+not an API key.
+
+## What pi‑ai supports
+
+- Provider: `amazon-bedrock`
+- API: `bedrock-converse-stream`
+- Auth: AWS credentials (env vars, shared config, or instance role)
+- Region: `AWS_REGION` or `AWS_DEFAULT_REGION` (default: `us-east-1`)
+
+## Setup (manual)
+
+1) Ensure AWS credentials are available on the **gateway host**:
+
+```bash
+export AWS_ACCESS_KEY_ID="AKIA..."
+export AWS_SECRET_ACCESS_KEY="..."
+export AWS_REGION="us-east-1"
+# Optional:
+export AWS_SESSION_TOKEN="..."
+export AWS_PROFILE="your-profile"
+```
+
+2) Add a Bedrock provider and model to your config:
+
+```json5
+{
+  models: {
+    providers: {
+      "amazon-bedrock": {
+        baseUrl: "https://bedrock-runtime.us-east-1.amazonaws.com",
+        api: "bedrock-converse-stream",
+        models: [
+          {
+            id: "anthropic.claude-3-7-sonnet-20250219-v1:0",
+            name: "Claude 3.7 Sonnet (Bedrock)",
+            reasoning: true,
+            input: ["text"],
+            cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
+            contextWindow: 200000,
+            maxTokens: 8192
+          }
+        ]
+      }
+    }
+  },
+  agents: {
+    defaults: {
+      model: { primary: "amazon-bedrock/anthropic.claude-3-7-sonnet-20250219-v1:0" }
+    }
+  }
+}
+```
+
+## Notes
+
+- Bedrock requires **model access** enabled in your AWS account/region.
+- If you use profiles, set `AWS_PROFILE` on the gateway host.
+- Reasoning support depends on the model; check the Bedrock model card for
+  current capabilities.
+- If you prefer a managed key flow, you can also place an OpenAI‑compatible
+  proxy in front of Bedrock and configure it as an OpenAI provider instead.
