+# Amazon Bedrock Mantle
+
+[Amazon Bedrock Mantle](https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-mantle.html) is Amazon Bedrock's distributed inference engine (Project Mantle) that exposes an **OpenAI-compatible API** for Bedrock-hosted models.
+
+Use this provider to call Bedrock Mantle models with accurate **AWS Bedrock pricing** instead of OpenAI pricing.
+
+:::tip
+
+**We support ALL Bedrock Mantle models, just set `model=bedrock_mantle/<model-id>` as a prefix when sending litellm requests**
+
+:::
+
+## API Key
+
+```python
+# env variable
+os.environ['BEDROCK_MANTLE_API_KEY'] = "your-aws-bedrock-api-key"
+
+# optional: override region (defaults to us-east-1)
+os.environ['BEDROCK_MANTLE_REGION'] = "us-east-1"  # or use AWS_REGION
+```
+
+## Supported Models
+
+| Model | Context Window | Input (per 1M tokens) | Output (per 1M tokens) |
+|-------|---------------|----------------------|------------------------|
+| `openai.gpt-oss-120b` | 131K | $0.15 | $0.60 |
+| `openai.gpt-oss-20b` | 131K | $0.075 | $0.30 |
+| `openai.gpt-oss-safeguard-120b` | 131K | $0.15 | $0.60 |
+| `openai.gpt-oss-safeguard-20b` | 131K | $0.075 | $0.30 |

+
+response = completion(
+    model="bedrock_mantle/openai.gpt-oss-120b",

+import os
+
+os.environ['BEDROCK_MANTLE_API_KEY'] = "your-bedrock-api-key"
+
+response = completion(
+    model="bedrock_mantle/openai.gpt-oss-120b",
+    messages=[{"role": "user", "content": "hello from litellm"}],
+    stream=True,
+)
+
+for chunk in response:
+    print(chunk)
+```
+
+</TabItem>
+<TabItem value="async" label="Async">
+
+```python
+import asyncio
+from litellm import acompletion
+import os
+
+os.environ['BEDROCK_MANTLE_API_KEY'] = "your-bedrock-api-key"
+
+async def main():
+    response = await acompletion(
+        model="bedrock_mantle/openai.gpt-oss-120b",
+        messages=[{"role": "user", "content": "hello from litellm"}],
+    )
+    print(response)
+
+asyncio.run(main())
+```
+
+</TabItem>
+</Tabs>
+
+## Region Configuration
+
+The API base URL is `https://bedrock-mantle.{region}.api.aws/v1`. Region is resolved in this order:
+
+1. `BEDROCK_MANTLE_REGION` env var
+2. `AWS_REGION` env var
+3. Default: `us-east-1`
+
+**Supported regions:** `us-east-1`, `us-east-2`, `us-west-2`, `eu-west-1`, `eu-west-2`, `eu-central-1`, `eu-south-1`, `eu-north-1`, `ap-northeast-1`, `ap-south-1`, `ap-southeast-3`, `sa-east-1`
+
+```python
+import os
+os.environ['BEDROCK_MANTLE_REGION'] = "eu-west-1"
+
+# or pass api_base directly
+response = completion(
+    model="bedrock_mantle/openai.gpt-oss-120b",
+    messages=[{"role": "user", "content": "hello"}],
+    api_base="https://bedrock-mantle.eu-west-1.api.aws/v1",
+)
+```
+
+## Usage with LiteLLM Proxy
+
+### 1. Set Bedrock Mantle models on config.yaml
+
+```yaml
+model_list:
+  - model_name: gpt-oss-120b
+    litellm_params:
+      model: bedrock_mantle/openai.gpt-oss-120b
+      api_key: os.environ/BEDROCK_MANTLE_API_KEY
+      # optional region override:
+      api_base: "https://bedrock-mantle.us-east-1.api.aws/v1"
+
+  - model_name: gpt-oss-20b
+    litellm_params:
+      model: bedrock_mantle/openai.gpt-oss-20b
+      api_key: os.environ/BEDROCK_MANTLE_API_KEY
+```
+
+### 2. Start the proxy
+
+```shell
+litellm --config /path/to/config.yaml
+```
+
+### 3. Send a request
+
+```python
+import openai
+
+client = openai.OpenAI(
+    api_key="anything",
+    base_url="http://0.0.0.0:4000",
+)
+
+response = client.chat.completions.create(
+    model="gpt-oss-120b",
+    messages=[{"role": "user", "content": "hello from litellm"}],
+)
+print(response)
+```
