+`baseUrl` indicates the URL Meilisearch queries when users submit questions to your chat interface. This is mandatory for Azure OpenAI, vLLM, and AWS Bedrock Mantle sources.
 
 `prompts.system` gives the conversational search bot the baseline context of your users and their questions. [The `prompts` object accepts a few other fields](/reference/api/chats#prompts) that provide more information to improve how the agent uses the information it finds via Meilisearch. In real-life scenarios filling these fields would improve the quality of conversational search results.
 
+### Using AWS Bedrock Mantle
+
+AWS Bedrock Mantle provides OpenAI-compatible API endpoints for Amazon Bedrock models. To use it with Meilisearch, you'll need an [AWS Bedrock API key](https://docs.aws.amazon.com/bedrock/latest/userguide/getting-started-api-keys.html) and configure your workspace with the Mantle endpoint:
+
+```bash
+curl \
+  -X PATCH 'MEILISEARCH_URL/chats/WORKSPACE_NAME/settings' \
+  -H 'Authorization: Bearer MEILISEARCH_KEY' \
+  -H 'Content-Type: application/json' \
+  --data-binary '{
+    "source": "openAi",
+    "apiKey": "YOUR_AWS_BEDROCK_API_KEY",
+    "baseUrl": "https://bedrock-mantle.AWS_REGION.api.aws/v1",
+    "prompts": {
+      "system": "You are a helpful assistant. Answer questions based only on the provided context."
+    }
+  }'
+```
+
+Replace `AWS_REGION` with your preferred AWS region (e.g., `us-west-2`, `us-east-1`, `eu-west-1`). When making requests, use Bedrock Mantle model IDs like `openai.gpt-oss-120b`.
+
+<Note>
+AWS Bedrock API keys embed the region into the token. Ensure your API key is generated in the same region as the `baseUrl` endpoint you're using. For example, if using `https://bedrock-mantle.us-west-2.api.aws/v1`, generate your API key in the `us-west-2` region.
